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

TAIPEI, Taiwan – July 06, 2022 — Macronix International Co., Ltd.
(TSE: 2337), a leading manufacturer of integrated devices in the
market for non-volatile memory (NVM), 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 fast VC4-based booting
systems, enabling them to meet real-time computing requirements.
Capable of a read speed of up to 400MB/s and low random latency, the MX25UW51245G provides VC4 reference boards with the flash
storage space required to start up the R-Car S4 SoC.

“Macronix and Renesas still have a collaborative relationship,
and we join forces again to bring our respective technologies
together and empowering designers with advanced automotive electronics
solutions,” said Macronix Vice President Marketing FL Ni. “The VC4”
evaluation platform with our MX25UW51245G will help to make 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 utilize 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 512Mb
density, an Automotive Grade 1 temperature range from -40 0C to +125 0C
and provides functional safety up to Automotive Safety Integrity Level
D (ASIL D). Memory quality and performance have been improved
substantially due to Macronix’s highly efficient technology and know-how.

The VC4 system is based on a complete Renesas chipset, the centerpiece
of which the R-Car S4 with 8x Cortex®A55 cores with 8MB of
SRAM, advanced cybersecurity and a rich selection of automotive
interfaces. The VC4 provides functional safety up to ASIL D along with:
the ability to have a wide range of connectivity within the
vehicle giving developers a rich environment for fast
prototypes. It provides a Gigabit Ethernet switch with three ports and a
integrated RH850 MCU functionality, which
customer’s bill of materials.

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