Renesas Debuts New Group in Popular RA0 Series with Best-in-Class Power Consumption and Extended Temperature Range
  Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today introduced the RA0E2 microcontroller (MCU) Group based on the Arm® Cortex®-M23 processor. The new, cost-competitive devices offer extremely low power consumption, extended temperature range, and a wide variety of peripheral functions and safety features.  Renesas introduced the RA0 MCU series in 2024 and it has quickly become very popular with a wide range of customers due to its affordability and low power consumption. RA0E1 devices have already been adopted in consumer electronics, appliance and white goods, power tools, industrial monitoring and other applications.  RA0E2 MCUs are fully compatible with RA0E1 devices, offering pin-expansion while maintaining the same peripherals and ultra-low power. This compatibility lets customers re-use existing software assets. The new devices deliver industry-leading power consumption of only 2.8mA current in active mode, and 0.89 mA in sleep mode. In addition, an integrated High-speed On-Chip Oscillator (HOCO) enables the fastest wake-up time for this class of microcontroller. The fast wake-up enables the RA0 MCUs to stay in Software Standby mode more of the time, where power consumption drops to a minuscule 0.25 µA.  Renesas’ RA0E1 and RA0E2 ultra-low power MCUs deliver an ideal solution for battery-operated consumer electronics devices, small appliances, industrial system control and building automation application.  Feature Set Optimized for Low Cost  The RA0E2 devices have a feature set optimized for cost-sensitive applications. They offer a wide operating voltage range of 1.6V to 5.5V so customers don’t need a level shifter/regulator in 5V systems. The RA0 MCUs also integrate timers, serial communications, analog functions, safety functions and security functionality to reduce customer BOM cost. A wide range of packaging options is also available, including a tiny 5mm x 5mm 32-lead QFN.  In addition, the new MCU’s high-precision (±1.0%) HOCO improves baud rate accuracy and enables designers to forego a standalone oscillator. Unlike other HOCOs in the industry, it maintains this precision in environments from -40°C to 125°C. This wide temperature range enables customers to avoid costly and time-consuming “trimming,” even after the reflow process.  “The market reception for our RA0 Series has exceeded even our own high expectations,” said Daryl Khoo, Vice President of the Embedded Processing Marketing Division at Renesas. “The RA0E2 Group MCUs deliver the same ultra-low power and price point that have been so popular with our customers. The addition of extended temperature range and more memory opens up even more applications and use cases. We plan to further expand the RA0 product lineup, delivering optimal solutions for 8-16 bit MCU users transitioning to 32-bit MCUs.”  Key Features of the RA0E2 Group MCUs  Core: 32MHz Arm Cortex-M23  Memory: Up to 128KB integrated Code Flash memory and 16KB SRAM  Extended Temperature Range: Ta -40°C to 125°C  Timers: Timer array unit (16b x 8 channels), 32-bit interval timer (8b x 4 channels), RTC  Communications Peripherals: 3 UARTs, 2 Async UART, 6 Simplified SPIs, 2 I2C, 6 Simplified I2Cs  Analog Peripherals: 12-bit ADC, temperature sensor, internal reference voltage  Safety: SRAM parity check, invalid memory access detection, frequency detection, A/D test, output level detection, CRC calculator, register write protection  Security: Unique ID, TRNG, AES libraries, Flash read protection  Packages: 32- and 48-lead QFNs, 32-, 48-, and 64-pin LQFP  The new RA0E2 Group MCUs are supported by Renesas’ Flexible Software Package (FSP).

ROHM Develops New High Power Density SiC Power Modules Compact high heat dissipation design sets a new standard for OBCs
  ROHM has developed the new 4-in-1 and 6-in-1 SiC molded modules in the HSDIP20 package optimized for PFC and LLC converters in onboard chargers (OBC) for xEVs (electric vehicles). The lineup includes six models rated at 750V (BSTxxx1P4K01) and seven products rated at 1200V (BSTxxx2P4K01). All basic circuits required for power conversion in various high-power applications are integrated into a compact module package, reducing the design workload for manufacturers and enabling the miniaturization of power conversion circuits in OBCs and other applications.  In recent years, the rapid electrification of cars is driving efforts to achieve a decarbonized society. Electric vehicles are seeing higher battery voltages to extend the cruising range and improve charging speed, creating a demand for higher output from OBCs and DC-DC converters. At the same time, there is an increasing need in the market for greater miniaturization and lighter weight for these applications, requiring technological breakthroughs to improve power density - a key factor - while enhancing heat dissipation characteristics that could otherwise hinder progress. ROHM’s HSDIP20 package addresses these technical challenges that were previously becoming difficult to overcome with discrete configurations, contributing to both higher output and the downsizing of electric powertrains.  The HSDIP20 features an insulating substrate with excellent heat dissipation properties that suppresses the chip temperature rise even during high power operation. When comparing a typical OBC PFC circuit utilizing six discrete SiC MOSFETs with top-side heat dissipation to ROHM’s 6-in-1 module under the same conditions, the HSDIP20 package was verified to be approx. 38°C cooler (at 25W operation). This high heat dissipation performance supports high currents even in a compact package, achieving industry-leading power density more than three times higher than top-side cooled discretes and over 1.4 times that of similar DIP type modules. As a result, in the PFC circuit mentioned above, the HSDIP20 can reduce mounting area by approx. 52% compared to top-side cooled discrete configurations, greatly contributing to the miniaturization of power conversion circuits in applications such as OBCs.  Going forward, ROHM will continue to advance the development of SiC modules that balance miniaturization with high efficiency while also focusing on the development of automotive SiC IPMs that provide higher reliability in a smaller form factor.  Product Lineup  *1: Tc=25°C VGS=18V *2: Combines chips with different ON resistances  *3: Q1, Q4 pins *4: Q2, Q3, Q5, Q6 pins  Application Examples  Power conversion circuits like PFC and LLC converters are commonly used in the primary side circuits of industrial equipment, allowing the HSDIP20 to also contribute to the miniaturization of applications in both the industrial and consumer electronics fields.  ◇ Automotive systems  Onboard chargers, electric compressors and more.  ◇ Industrial equipment  EV charging stations, V2X systems, AC servos, server power supplies, PV inverters, power conditioners, etc.  Sales Information  Pricing: $100/unit (samples, excluding tax)  Availability: OEM quantities (April 2025)  Supporting Information  ROHM is committed to providing application-level support, including the use of in-house motor testing equipment. A variety of supporting materials are also offered such as simulations and thermal designs that enable quick evaluation and adoption of HSDIP20 products. Two evaluation kits are available as well, one for double-pulse testing and the other for 3-phase full bridge applications, enabling evaluation under close to actual circuit conditions.  For more information, please contact AMEYA360 or visit the contact page on ROHM’s website.  EcoSiC™ Brand  EcoSiC™ is a brand of devices that utilize silicon carbide, which is attracting attention in the power device field for performance that surpasses silicon. ROHM independently develops technologies essential for the advancement of SiC, from wafer fabrication and production processes to packaging, and quality control methods. At the same time, we have established an integrated production system throughout the manufacturing process, solidifying our position as a leading SiC supplier.  ・EcoSIC™ is a trademark or registered trademark of ROHM Co., Ltd.  Terminology  Power Factor Correction (PFC)  A circuit that enhances the power factor by shaping the waveform of input power in the power supply circuit. By using a PFC circuit, the input power is made closer to a sine wave (power factor = 1), improving power conversion efficiency. While PFC circuits typically rely on diode rectification, OBCs often employ active bridge rectification using MOSFETs or bridgeless PFC. This approach is favored because MOSFETs offer lower switching losses, and especially in high power PFCs, using SiC MOSFETs reduces heat generation and power losses.  LLC Converter  A type of resonant DC-DC converter known for its high efficiency with low noise power conversion. The name LLC comes from its basic configuration, which combines two inductors (L) and a capacitor (C) in the circuit. By forming a resonant circuit, switching losses are significantly reduced, making it ideal for applications requiring high efficiency, such as OBCs, power supplies for industrial equipment, and server power supplies.

GigaDevice's GD5F1GM9 Series High-Speed QSPI NAND Flash Sets New Benchmark with Breakthrough Read Speeds for Accelerated Application Startup
  GigaDevice, a leading semiconductor company specializing in Flash Memory, 32-bit Microcontrollers (MCUs), Sensors, Analog products and solutions, announces the launch of its GD5F1GM9 high-speed QSPI NAND Flash, which features breakthrough read speeds and innovative Bad Block Management (BBM) functionality.  The GD5F1GM9 series combines the high-speed read performance of NOR Flash with the large capacity and cost-effectiveness of NAND Flash. These innovations address key industry challenges of slow response times and vulnerability to bad block interference associated with traditional SPI NAND Flash. The GD51GM9 launch will open new growth opportunities for SPI NAND Flash, making it the ideal choice for fast-boot applications in sectors such as security, industrial, and IoT.  The GD5F1GM9 series high-speed QSPI NAND Flash is built on a 24nm process node. The series supports both 3V and 1.8V operating voltages as well as high-speed read modes including Continuous Read, Cache Read, and Auto Load Next Page. Continuous Read and Auto Load Next Page modes are newer read features added on this series, offering users versatile read options to further accelerate code and data fetch. These read modes utilize the new parallel computation approach for its ECC (Error Correction Code) design, replacing the previous serial computation method. This innovation significantly reduces the calculation time for the built-in ECC.  The 3V version of the series achieves a continuous read rate of up to 83MB/s in Continuous Read mode, operating at a maximum clock frequency of 166MHz. The 1.8V version has a continuous read rate of up to 66MB/s and supports a maximum clock frequency of 133MHz. The results in GD5F1GM9’s read speeds are up to 3 times faster than traditional SPI NAND products at the same frequency. These design advantages improve data access throughput, reduce system boot time, and lower overall system power consumption.  As bad blocks from the factory are inherent issues in NAND Flash, the GD5F1GM9 incorporates an on-chip Advanced Bad Block Management (BBM) to ensure comprehensive functionality of Continuous Read mode. Continuous Read allows read access of the full memory array with a single Read command in aid of the executed BBM that link bad block addresses to good block addresses. Read access will then automatically skip the bad block due to the established link access to the remap and linked good physical block address.  From the factory, the GD5F1GM9 series guarantees the first 256 blocks are good blocks. While there will be bad blocks from the factory and possible new bad blocks may arise during usage that needs to be managed, the BBM feature can create a logical block address to the physical block address link, allowing users to swap and replace bad blocks and the associated access will be on a good block once the BBM link is setup.  The device can support up to 20 Look Up Table BBM Links to further compliment Continuous Read mode functionality. This not only significantly improves resource utilization but also simplifies system design.  “Currently, the generally slow read speed of SPI NAND Flash has become a major bottleneck in enhancing boot performance of key applications,” said Ruwei Su, GigaDevice vice president and general manager of Flash BU, "The launch of GD5F1GM9 series high-speed QSPI NAND Flash sets a new performance benchmark in the market. This series effectively addresses the read speed limitations of traditional SPI NAND Flash and offers a new solution for bad block management, making it an ideal alternative for NOR Flash users with growing capacity needs. In the future, GigaDevice will continue to refine its underlying technologies to provide customers with more efficient and reliable storage solutions."  The GD5F1GM9 series offers 1Gb capacity with 3V/1.8V voltage options and supports WSON8 8x6mm, WSON8 6x5mm, and BGA24 (5×5 ball array) 5x5 ball package options.

ROHM Develops Class-Leading* Low ON-Resistance, High-Power MOSFETs for High-Performance Enterprise and AI Servers
  ROHM has developed N-channel power MOSFETs featuring industry-leading* low ON-resistance and wide SOA capability. They are designed for power supplies inside high-performance enterprise and AI servers.  The advancement of high-level data processing technologies and the acceleration of digital transformation have increased the demand for data center servers. At the same time, the number of servers equipped with advanced computing capabilities for AI processing is on the rise and is expected to continue to grow. These servers operate 24 hours a day, 7 days a week – ensuring continuous operation. As a result, conduction losses caused by the ON-resistance of multiple MOSFETs in the power block have a significant impact on system performance and energy efficiency. This becomes particularly evident in AC-DC conversion circuits, where conduction losses make up a substantial portion of total power loss – driving the need for low ON-resistance MOSFETs.  Additionally, servers equipped with a standard hot-swap function, which allow for the replacement and maintenance of internal boards and storage devices while powered ON, experience a high inrush current during component exchanges. Therefore, to protect server components and MOSFETs from damage, a wide Safe Operating Area (SOA) tolerance is essential.  To address these challenges, ROHM has developed its new DFN5060-8S package that supports the packaging of a larger die compared to conventional designs, resulting in a lineup of power MOSFETs that achieve industry-leading* low ON-resistance along with wide SOA capability. These new products significantly contribute to improving efficiency and enhancing reliability in server power circuits.  The new lineup includes three products. The RS7E200BG (30V) is optimized for both secondary-side AC-DC conversion circuits and hot-swap controller (HSC) circuits in 12V power supplies used in high-performance enterprise servers. The RS7N200BH (80V) and RS7N160BH (80V) are ideal for secondary AC-DC conversion circuits in 48V AI server power supplies.  All three models feature the newly developed DFN5060-8S package (5.0mm × 6.0mm). The package increases the internal die size area by approximately 65% compared to the conventional HSOP8 package (5.0mm × 6.0mm). As a result, the RS7E200BG (30V) and RS7N200BH (80V) achieve ON-resistances of 0.53mΩ and 1.7mΩ (at VGS = 10V), respectively – both of which rank among the best in the industry in the 5.0mm × 6.0mm class, significantly contributing to higher efficiency in server power circuits.  Moreover, ROHM has optimized the internal clip design to enhance heat dissipation, further improving SOA tolerance, which contributes to ensuring application reliability. Notably, the RS7E200BG (30V) achieves an SOA tolerance of over 70A at a pulse width of 1ms and VDS = 12V, which is twice that of the conventional HSOP8 package MOSFETs under the same conditions, ensuring industry-leading SOA performance in a 5.0mm × 6.0mm footprint.  Going forward, ROHM plans to gradually begin mass production of power MOSFETs compatible with hot-swap controller circuits for AI servers in 2025, continuing to expand its lineup that contributes to greater efficiency and reliability across a wide range of applications.  Product Lineup  EcoMOS™ Brand  EcoMOS™ is ROHM's brand of silicon power MOSFETs designed for energy-efficient applications in the power device sector.  Widely utilized in applications such as home appliances, industrial equipment, and automotive systems, EcoMOS™ provides a diverse lineup that enables product selection based on key parameters such as noise performance and switching characteristics to meet specific requirements.  EcoMOS™ is a trademark or registered trademark of ROHM Co., Ltd.  Application Examples  ・AC-DC conversion and HSC circuits for 12V high-performance enterprise server power supplies  ・AC-DC conversion circuits for 48V AI server power supplies  ・48V industrial equipment power supplies (i.e. fan motors)  Terminology  Low ON-Resistance (RDS(on))  The resistance value between the Drain and Source of a MOSFET during operation. A smaller RDS(on) results in lower power loss during operation.  SOA (Safe Operating Area) Tolerance  The range of voltage and current within which a device can operate safely without damage. Exceeding this range can lead to thermal runaway or device failure, making SOA tolerance a critical factor, especially in applications prone to inrush current or overcurrent.  Power MOSFET  A type of MOSFET used for power conversion and switching applications. N-channel MOSFETs are the mainstream choice, as they become conductive when a positive voltage is applied to the gate relative to the source, offering lower ON-resistance and higher efficiency than P-channel variants. Due to their low loss and high-speed switching capabilities, power MOSFETs are widely used in power circuits, motor drive circuits, and inverters.  Hot-Swap Controller (HSC)  A specialized integrated circuit (IC) that enables hot-swap functionality, allowing components to be inserted or removed while the power supply system remains active. It plays a crucial role in managing inrush current that occurs during component insertion, protecting both the system and connected components from damage.  Inrush Current  A sudden surge of current that momentarily exceeds the rated value when an electronic device is powered ON. Proper control of this current reduces stress on power circuit components, helping to prevent device failure and stabilize the system.

Renesas Introduces Low-Power Bluetooth Low Energy SoC for Automotive Applications
  Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today introduced a new industry-leading Bluetooth chip that combines a radio transceiver, an Arm® M0+ microcontroller, memory, peripherals and security features in a compact SoC design. The DA14533, the first automotive-qualified device in the company’s Bluetooth® Low Energy system-on-chip (SoC) family, includes advanced power management features to simplify system integration and reduce power consumption. With its software stack qualified against Bluetooth Core 5.3 and support for extended temperatures, developers can jump-start projects in applications from tire pressure monitoring and keyless entry to wireless sensors and battery management systems.  Optimized Design to Deliver Unparalleled Power Efficiency  Building on Renesas’ leadership in Bluetooth LE SoCs (SmartBond Tiny Family) with industry-leading low power consumption, the new DA14533 includes some of the most advanced power management features in the industry. The device includes an integrated DC-DC buck converter, which accurately adjusts the output voltage according to system requirements. Active system power consumption is lower than comparable devices in the market, requiring only 3.1mA during transmission and 2.5mA during reception. In hibernation mode, the current drops to 500nA. These power management and power-saving features help extend the operational life of small-capacity battery-powered systems and meet the stringent power requirements of tire pressure monitoring systems’ mission profile.  Auto-Grade AEC-Q100 Qualified and Up-to-Date Security Features  The DA14533 is an AEC-Q100 Grade 2 qualified device, which means the device has passed strict testing to sustain quality and reliability in harsh automotive environments. Moreover, the device’s extended temperature range (-40 to +105°C) ensures reliable performance in demanding conditions, making it ideal for automotive and industrial systems where stability and durability are essential. Qualified against Bluetooth Core 5.3 specifications, the device contains the latest security features to safeguard connected devices from various threats.  “Our SmartBond Tiny SoC family has seen remarkable success in the industrial market, with over 100 million units shipped to date,” said Chandana Pairla, VP of Connectivity Solutions Division at Renesas. “This new automotive-grade device will enable a new class of Bluetooth LE applications that demand high power efficiency, a small footprint and broader temperature tolerance for next-generation battery-powered automotive and industrial systems.”  Lower Bill-of-Materials Reduces Costs and Simplifies Development  Similar to other Bluetooth LE SoC devices in the SmartBond Tiny family, the DA14533 only requires 6 external components, offering a best-in-class engineering bill of materials (eBOM).  A single external crystal oscillator (XTAL) is used for both active and sleep modes, eliminating the need for a separate oscillator for sleep mode. Its ultra-compact design – available in a WFFCQFN 22-pin 3.5 x 3.5 mm package – makes the device the smallest automotive Bluetooth LE SoC on the market. With its compact design and low eBOM, the device integrates seamlessly into space-constrained systems, reducing overall system costs and accelerating time-to-market for customers.  Key Features of the DA14533  Arm® Cortex®-M0+ microcontroller – Standalone application processor or data pump in hosted systems  64KB RAM and 12KB One-Time Programmable (OTP) memory  2.4 GHz radio transceiver  Integrated low IQ buck DC-DC converter  External SPI flash  Single XTAL operation (single crystal oscillator)  Software stack qualified against Bluetooth Core 5.3  AEC-Q100 Grade 2-qualified with wide operating temperature range support (-40 to +105°C)  WFFCQFN 22-pin 3.5 x 3.5 mm package
