　　Renesas Electronics has announced the sample shipment of the industry's first on-chip flash memory microcontroller (MCU) that uses a 28nm process technology.

　　The RH850/E2x Series MCU incorporates up to six 400MHz CPU cores, making it the first on-chip flash memory automotive MCU to achieve the industry's highest processing performance of 9600 MIPS. The series also features a built-in flash memory of up to 16MB as well as enhanced security functions and functional safety.

　　Renesas is describing the 28nm-generation automotive control MCU as a breakthrough product featuring next-generation technology that's intended to support complex automotive control. OEMs and Tier 1 manufacturers in the automotive space have started to adopt the new 28nm MCU,

　　According to the company as the automotive industry looks to develop environmentally-friendly vehicles, next-generation fuel-efficient engines will require much higher processing performance in order to allow the implementation of new fuel combustion systems. High processing performance and high integration densities will be required to achieve miniaturisation and higher efficiency in the motors and inverters used in electric vehicles (EV) and plug-in hybrid electric vehicles (PHEV).

　　Looking to address these requirements, and when compared to the earlier 40nm MCUs, the RH850/E2x Series of MCUs are able to achieve approximately three times the performance at the same power level. The RH850/E2x also includes enhanced sensor interfaces which are necessary for precise automotive control functions.

　　The RH850/E2x Series is also equipped with up to 16MB of flash ROM and it is possible to only update certain arbitrary areas during program operation. The RH850/E2x Series comes with improved serial interfaces, including up to ten channels of CAN FD and one Ethernet channel. Security functions that support Evita Medium enable the MCUs to support safe and rapid OTA updating of the software.

　　Targeting ASIL-D, the highest level of the ISO 26262 functional safety standard for automotive E/E systems, the RH850/E2x Series has adopted the dual core lock step CPU structure that is able to guarantee that the calculations performed by two CPU cores are identical. The RH850/E2x also provides up to four sets of CPU pairs, and features a variety of hardware functional safety improvements.

　　In applications where a system malfunction could lead to life-endangering accidents, these features immediately detect faults should a malfunction occur and allow system safety to be maintained.

　　Renesas will provide safety analysis tools that can flexibly support a wide range of use cases to implement safe systems.

　　To assure scalability in the RH850/E2x Series, in addition to the 28nm flash memory MCU, Renesas has also launched a 40nm process MCU.

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.

Renesas Introduces Industry’s First Complete Memory Interface Chipset Solutions for Second-Generation DDR5 Server MRDIMMs

　　Renesas Electronics Corporation (TSE: 6723), a premier supplier of advanced semiconductor solutions, today announced that it has delivered the industry’s first complete memory interface chipset solutions for the second-generation DDR5 Multi-Capacity Rank Dual In-Line Memory Modules (MRDIMMs).　　The new DDR5 MRDIMMs are needed to keep pace with the ever-increasing memory bandwidth demands of Artificial Intelligence (AI), High-Performance Compute (HPC) and other data center applications. They deliver operating speeds up to 12,800 Mega Transfers Per Second (MT/s), a 1.35x improvement in memory bandwidth over first-generation solutions. Renesas has been instrumental in the design, development and deployment of the new MRDIMMs, collaborating with industry leaders including CPU and memory providers, along with end customers.　　Renesas has designed and executed three new critical components: the RRG50120 second-generation Multiplexed Registered Clock Driver (MRCD), the RRG51020 second-generation Multiplexed Data Buffer (MDB), and the RRG53220 second-generation Power Management Integrated Circuit (PMIC). Renesas also offers temperature sensor (TS), and serial presence detect (SPD) hub solutions in mass production, making it the only memory interface company that offers the complete chipset solutions for industry standard next-generation MRDIMMs as well as all other server and client DIMMs.　　“The demand for higher performance systems driven by AI and HPC applications is relentless,” said Davin Lee, Senior Vice President and General Manager of Analog & Connectivity and Embedded Processing. “Renesas is at the forefront of this trend, working with industry leaders to develop next-generation technology and specifications. These companies depend on Renesas to deliver the technical know-how and the production capabilities they require to meet unprecedented demand. Our latest chipset solutions for second-generation DDR5 MRDIMMs showcase our leadership in this market.”　　Renesas’ RRG50120 second-generation MRCD is used on the MRDIMMs to buffer the Command/Address (CA) bus, chip selects and the clocks between the host controller and DRAMs. It consumes 45% less power compared to the first-generation device, a critical specification for heat management in very high-speed systems. The RRG51020 Gen2 MDB is the other key device used in the MRDIMMs to buffer data from the host CPU to DRAMs. Both the new Renesas MRCD and MDB support speeds up to 12.8 Gigabytes per Second (GB/s). Additionally, Renesas’ RRG53220 next-generation PMIC offers best-in-class electrical-over-stress protection and superior power efficiency and is optimized for high-current and low-voltage operation.　　Availability　　Renesas is sampling the RRG50120 MRCD, the RRG51020 MDB, and the RRG53220 PMIC now, and expects the new products to be available for production in the first half of 2025.
