Macronix OctaBus™ Flash Memory Selected for Renesas VC4 Automotive Computing Development Platform

Macronix OctaBus MX25UW51245G NOR Flash Offers Boot Memory to Renesas R-CAR S4 SoC Based VC4 Vehicle Computer Reference Designs

TAIPEI, July 7, 2022 /PRNewswire/ — Macronix International Co., Ltd. (TSE: 2337), a leading integrated device manufacturer in the non-volatile memory (NVM) market, today announced that its MX25UW51245G Serial NOR Flash memory has been selected by Renesas Electronics Corporation for reference designs based on the Vehicle Computer Generation 4 (VC4) chipset. The powerful MX25UW51245G will provide the VC4 platform, based on the Renesas R-Car S4 system on a chip (SoC), with critical memory that enables fast boot times in automotive computer designs.

Fast, reliable flash memory is essential for quickly booting VC4-based systems to meet real-time computing requirements. Capable of achieving up to 400MB/s read speed and low random latency, the MX25UW51245G provides VC4 reference boards with the flash storage required for the initial start-up of the R-Car S4 SoC.

“Macronix and Renesas continue to enjoy a collaborative relationship and we are once again joining forces to bring together our respective technologies and provide designers with advanced automotive electronics solutions,” said Macronix Vice President of Marketing FL Ni† “The VC4 evaluation platform with our MX25UW51245G will help unleash the power of the R-Car S4 SoC and VC4 in next-generation automotive systems.”

“The Renesas VC4 evaluation platform streamlines the development of automotive gateway and zone controller systems that can take advantage of the performance and safety features in both R-Car S4 SoC and MX25UW51245G,” said Takashi Yasumasu, Vice President of Automotive Core Technology Development Division at Renesas .

A core member of Macronix’s highly efficient NOR flash memory line with its OctaBus™ interface, the MX25UW51245G has a density of 512 Mb, an Automotive Grade 1 temperature range from -40 to +125 ℃ and offers functional safety up to Automotive Safety Integrity Level D (ASIL D). Memory quality and performance are greatly enhanced by Macronix’s highly efficient technology and know-how.

The VC4 system is based on a complete Renesas chipset, centered on the R-Car S4 featuring 8x Cortex®A55 cores with 8MB of SRAM, advanced cybersecurity and a rich selection of automotive interfaces. The VC4 offers functional safety up to ASIL D, along with the ability to simulate a wide range of in-vehicle connectivity, providing developers with a rich environment for rapid prototyping. It provides a three-port Gigabit Ethernet switch with integrated RH850 MCU functionality, which dramatically reduces the customer’s bill of materials.

Macronix and Renesas have a rich history of complementary products and evaluation solutions. Macronix is ​​also a member of the Renesas RZ Partner Ecosystem Solutions program and the R-Car Consortium, and a wide variety of its flash memory products are represented on several Renesas RZ evaluation boards, including the OctaBus, ArmorFlash™ and e.MMC ™ families.
