Product details
Overview
M10162040108X0PSAR from Renesas is a 16Mb serial STT-MRAM non-volatile memory IC with QSPI interface, 108MHz SDR clock rate, 1.71–2.0V supply, and industrial-plus (−40°C to +105°C) operation. It delivers SRAM-compatible read/write timing, zero write latency, and persistent data retention without backup power-ideal for real-time industrial control logging.
For engineers reviewing the M10162040108X0PSAR datasheet, M10162040108X0PSAR pinout, M10162040108X0PSAR application, or M10162040108X0PSAR equivalent, key selection criteria include its 108MHz SDR QSPI performance, hardware/software write protection, 256-byte augmented storage array, JEDEC reset support, and dual-temperature-grade availability in 8-pin SOIC.
Technical Context
The M10162040108X0PSAR implements a 40nm pMTJ spin-transfer torque MRAM array with quad SPI (4-4-4) interface supporting both SDR (108MHz) and DDR (54MHz) modes. Its architecture includes dedicated command/address/data paths, eXecute-In-Place (XIP) capability, and dual low-power states (Deep Power Down and Hibernate) with full configuration retention.
It integrates hardware-based write protection via WP# pin and software-based protection through configurable status and block-protection registers. The 256-byte Augmented Storage Array is segmented into eight 32-byte user-programmable, individually protectable sections-separate from main memory addressing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial non-volatile memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress Semiconductors FM25V16-G | 16Mb F-RAM; 3.3V only; 40MHz max SPI clock; no QSPI or XIP support | Limited to lower-bandwidth logging; lacks quad interface and execute-in-place capability | Select when 3.3V supply and moderate speed suffice, and QSPI/XIP are not required |
| Winbond W25Q16JW-QI | 16Mb Quad SPI NOR Flash; 1.65–1.95V; requires erase-before-write; 100k-cycle endurance | Needs erase management firmware; unsuitable for frequent small writes or real-time logging | Select only for code storage where infrequent updates and erase tolerance are acceptable |
Compared with FM25V16-G and W25Q16JW-QI, the M10162040108X0PSAR uniquely combines 108MHz QSPI speed, true random write without erase, and industrial-plus temperature rating-making it the only option for high-frequency, mission-critical data capture in thermally demanding environments.

FAQ
What is the operating voltage range for the M10162040108X0PSAR?
The M10162040108X0PSAR operates from 1.71V to 2.00V. This 1.8V nominal supply range ensures compatibility with modern low-power microcontrollers and FPGA I/O banks, while maintaining full functionality across the entire industrial-plus temperature range (−40°C to +105°C). The device does not support 3.0V operation-only the '1' suffix variants (e.g., M10162040108X0PSA3) are rated for 2.7–3.6V.
Does the M10162040108X0PSAR support Quad SPI (QPI) mode?
Yes, the M10162040108X0PSAR supports full QPI (4-4-4) mode with command, address, and data transferred simultaneously across four I/O lines. This mode enables maximum throughput at 108MHz SDR, delivering up to 432 MB/s effective bandwidth. QPI mode is enabled via configuration register settings and requires proper initialization sequence per the datasheet.
How is write protection implemented on the M10162040108X0PSAR?
The M10162040108X0PSAR implements dual-layer write protection: hardware-based via the WP# pin (active-low, disables status register writes when asserted), and software-based via configurable bits in the Status Register (BPSEL[2:0], TBSEL, SNPEN). Both mechanisms can be used independently or concurrently to protect main memory, augmented storage, and serial number fields against unintended modification.
What is the purpose of the Augmented Storage Array in the M10162040108X0PSAR?
The 256-byte Augmented Storage Array in the M10162040108X0PSAR is a physically separate, user-programmable memory region divided into eight 32-byte sections. Each section can be individually write-protected-enabling secure storage of calibration data, cryptographic keys, or device-specific identifiers without risking corruption of the main memory array.
Is the M10162040108X0PSAR pin-compatible with standard SPI NOR flash devices?
Yes, the M10162040108X0PSAR in 8-pin SOIC package uses identical pinout and footprint as industry-standard SPI NOR flash (e.g., Winbond W25Q series), including CS#, SO/IO1, WP#/IO2, GND, VCC, HOLD#/IO3, CLK, and SI/IO0. This allows drop-in replacement in existing designs-provided firmware supports MRAM-specific commands and timing.
