Macronix OctaBusTMFlash Memory Selected for Renesas VC4 Automotive Computing Development Platform

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

TAIPEI, Taiwan –  06 July, 2022 — 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 high-performance MX25UW51245G will provide the VC4 platform, based on Renesas R-Car S4 system on a chip (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 Macronix Vice President of Marketing F.L. Ni. “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, Vice President of Automotive Core Technology Development Division at Renesas.

A core member of Macronix’s highly efficient NOR flash memory line
featuring its OctaBus™ interface, the MX25UW51245G features 512Mb
density, an Automotive Grade 1 temperature range of -40 0C to +125 0C
and provides functional safety up to Automotive Safety Integrity Level
D  (ASIL D). The memory’s quality and performance are enhanced
substantially by Macronix’s high efficient 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, advanced cybersecurity and a rich selection of automotive
interfaces. The VC4 provides functional safety up to ASIL D, along with
the capability for simulating a wide range of connectivity inside the
vehicle thereby allowing developers a rich environment for rapid
prototyping. It offers an three-port Gigabit Ethernet switch and an
integrated RH850 MCU functionality, which drastically reduces the
customer’s bill of material.

Macronix and Renesas have a rich 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 broad range
of its flash memory products are represented in several Renesas RZ
evaluation boards, including the OctaBus, ArmorFlash™ and e.MMC™ families.
