Macronix Octaflash UW Series Memory Provides High-Density Flash Solutions for NXP S32Z and S32E Real-Time Processors

TAIPEI, Taiwan – June 28, 2022 — Macronix International Co., Ltd. (TSE:
2337) today announced that Macronix’s MX25UW high efficiency octaflash
flash memory family has been selected for NXP® Semiconductor’s S32Z and S32E real-time processors for safe integration of real-time
applications. The selection marks the companies’ next step in deploying
Macronix OctaBus Memory technology in NXP’s S32 Automotive Platform,
whose MCUs and processors are designed to address vehicles’
connectivity, security and safety challenges. This development also
reflects the growing need for performance, flexibility and temperature
tolerance in both processors and flash memory used in demanding
automotive applications.

Macronix’s MX25UW high efficiency octaflash flash memory family offers
devices with densities ranging from 64Mb (8MB) to 2Gb (256MB) in
Automotive Grade 1 (-40 0C to +125 0C). It supports built-in
error-correction code (ECC) for single-error correcting and double-error
detecting (SECDED), and Automotive Safety Integrity Level D (ASIL
D)-certified – the highest classification and the most stringent safety
level within the ISO 26262 automotive functional safety standard. The
memory features a single- or Octal-I/O interface, low power (1.7V to 2V)
and Double Transfer Rate (DTR) mode operation for fast data transfer of
up to 400 MHz – the fastest serial flash in the industry. The MX25UW
flash memory family provides a multiple-bank structure that allows high
efficiency operation. It’s an ideal solution for over-the-air (OTA)
update applications, which are becoming more prevalent in the “connected
car” market and enable a fast, efficient method of providing them with
up-to-date data.

The NXP S32Z and S32E real-time processors are designed for safe,
multi-application integration to support new domain and zonal vehicle
E/E architectures and software-defined vehicles. The S32Z processors are
ideal for safety processing and domain and zonal control, while the S32E
processors are ideal for electric vehicle (xEV) control and smart
actuation. They feature eight split-lock Arm® Cortex®-R52 cores running
up to 1 GHz, a Cortex-M33 lock-step pair of cores (system manager) and a
DSP/ML processor for advanced predictive control and machine learning
applications. They additionally include a CAN communications accelerator
(FlexLLCE), integrated Ethernet switch (NETC3) and hardware security
engine (HSE) that support public key infrastructure (PKI).  The S32Z and
S32E processors are certified for ISO/SAE 21434 cyber security and ISO
26262:2018 functional safety. They are AEC-Q100 Automotive Grade 1
compliant, supporting ambient temperatures between -40 0C to +125 0C.

NXP is the world’s largest supplier of automotive processors. Macronix
is a leading integrated device manufacturer in the non-volatile memory
(NVM) market, including flash memory solutions for the automotive market.

“Safety is a top priority in automotive electronic systems that use our
S32Z and S32E processors for real-time applications,” said Andy Birnie,
NXP Senior Director of Solutions & Applications for Automotive
Processors. “Macronix shares that same approach to automotive safety,
making the selection of the MX25UW flash memory family for our S32Z and
S32E processors straightforward.”

“Macronix has long emphasized quality, reliability and performance in
our flash memory solutions, especially for applications such as
automotive electronics, we’ve enhanced our product offerings for
automotive market by adding safety to the equation,” said Macronix Vice
President of Marketing F.L. Ni. “Our MX25UW high efficiency memory, with
its ASIL D certification, is the ideal complement to NXP’s S32Z and S32E
real-time processors in automotive electronic systems prioritizing the
safety of drivers, passengers and the general public.”

The NXP GreenBox 3 hardware platform integrates the S32E288 processor
with 32 MB of Macronix MX25UW25645G flash memory for evaluation and is supported by the NXP S32 Flash Tool.  For additional information on
