Renesas Selects Macronix MX25UW51245G Serial NOR Flash Memory for Vehicle Computer Gen 4 (VC4) Chipset

Macronix International Co., Ltd. announced that its MX25UW51245G Serial NOR flash memory has been selected by Renesas Electronics Corp. for reference designs based on the Vehicle Computer Generation 4 (VC4) chipset.

The performance MX25UW51245G will provide the VC4 platform, based on Renesas R-Car S4 SoC, with critical memory that enables fast boot-up times in automotive-computing designs.

Fast, reliable flash memory is essential to rapidly booting VC4-based systems, allowing them to adhere to real-time computing requirements. The MX25UW51245G, which can achieve up to 400MB/s read throughput and features low random latency, provides VC4 reference boards the flash storage needed for initial boot of the R-Car S4 SoC.

“Macronix and Renesas continue to enjoy a collaborative relationship, and we’re once again joining forces to bring our respective technologies together and empowering designers with advance automotive-electronics solutions,” said F.L. Ni, VP marketing, Macronix. “The VC4 evaluation platform featuring 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 leverage the performance and safety features in both R-Car S4 SoC and MX25UW51245G,” said Takashi Yasumasu, VP, automotive core technology development division, Renesas.

A core member of the company’s NOR flash memory line featuring its OctaBus interface, the MX25UW51245G features 512Mb density, an Automotive Grade 1 temperature range of -40 ℃ to +125 ℃ and provides functional safety up to Automotive Safety Integrity Level D (ASIL D). The memory’s quality and performance are enhanced substantially by the firm’s technology and know how.

The VC4 system is based on a complete Renesas chipset, the centerpiece of which is the R-Car S4 with 8x Cortex A55 cores which features 8MB of SRAM, cybersecurity and a rich selection of automotive interfaces. It provides functional safety up to ASIL D, along with the capability for simulating a range of connectivity inside the vehicle thereby allowing developers a rich environment for rapid prototyping. It offers an 3-port GEt switch and an integrated RH850 MCU functionality, which reduces the customer’s BoM.

The 2 companies have a history of complementary products and evaluation solutions. Macronix is also a member of Renesas RZ Partner Ecosystem Solutions program and the R-Car Consortium, and a range of its flash memory products are represented in several Renesas RZ evaluation boards, including the OctaBus, ArmorFlash and e.MMC families.
