Product details
Overview
M30042040108X0ISAR from Renesas is a 4Mb serial STT-MRAM non-volatile memory IC with QSPI interface, 108MHz SDR operation, 1.71–2.0V supply, and industrial temperature range (−40°C to +85°C), deployed in factory automation controllers for real-time parameter retention during power loss.
For engineers reviewing the M30042040108X0ISAR datasheet, M30042040108X0ISAR pinout, M30042040108X0ISAR application, or M30042040108X0ISAR equivalent, key selection considerations include its persistent SRAM timing compatibility, hardware/software write protection, 256-byte augmented storage array, and dual-package support (8-pin SOIC/8-pad WSON) for legacy footprint reuse.
Technical Context
The M30042040108X0ISAR implements a 40nm pMTJ spin-transfer torque MRAM array with true random access, enabling byte-level reads/writes without erase cycles. It supports Quad SPI (4-4-4) and Single Data Rate mode at 108MHz, with clock-edge-triggered transfers on rising edge for command/address and falling edge for data output.
It integrates hardware-based write protection via WP# pin and software-configurable block protection through Status Register bits (BPSEL[2:0], TBSEL), plus an independent 256-byte Augmented Storage Array with per-section write lock. Power management includes Deep Power Down (3µs entry, 400µs exit) and Hibernate modes preserving configuration and data.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 4Mbit (512KB); enables compact firmware logging and configuration storage without flash wear-out. |
| Interface | QSPI (4-4-4); supports high-throughput burst reads up to 108MB/s in SDR mode for real-time data capture. |

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 FM25V04-G | 4Mb F-RAM; 3.0V only (2.7–3.6V); max 40MHz SPI; no QSPI or DDR support. | Limited to lower-bandwidth control logging; lacks augmented storage and hibernate mode. | Select when cost sensitivity outweighs speed and feature requirements; verify voltage compatibility. |
| Infineon Technologies CY14B104N-ZSP25XI | 4Mb nvSRAM; 3.0V only; requires external capacitor for auto-store; 25ns access time but volatile-first architecture. | Suitable for legacy SRAM-drop-in designs; higher standby current and finite endurance (~1M cycles). | Choose only for direct SRAM pinout replacement where capacitor-based store/restore is acceptable. |
Compared with FM25V04-G and CY14B104N-ZSP25XI, the M30042040108X0ISAR delivers 2.7× higher interface bandwidth, eliminates external backup components, and guarantees infinite endurance-making it optimal for high-write industrial firmware and real-time data capture.

FAQ
What is the operating voltage range for M30042040108X0ISAR?
The M30042040108X0ISAR operates from 1.71V to 2.00V. This 1.8V nominal supply range is optimized for low-power industrial microcontrollers and eliminates the need for voltage translation when interfacing with 1.8V logic families. Operation outside this range is not guaranteed, and the device enters reset below VCC_RST (≤0.2V).
Does M30042040108X0ISAR support Quad SPI mode?
Yes, the M30042040108X0ISAR fully supports Quad SPI (4-4-4) mode with 108MHz SDR operation. In this mode, IO[3:0] carry command, address, and data simultaneously, enabling peak throughput of 108MB/s-critical for high-speed firmware updates and real-time data streaming in industrial edge devices.
How does the Augmented Storage Array in M30042040108X0ISAR function?
The M30042040108X0ISAR includes a dedicated 256-byte Augmented Storage Array, divided into eight 32-byte sections. Each section can be individually programmed and write-protected via configuration bits, making it ideal for storing immutable calibration data, device serial numbers, or cryptographic keys without risking corruption of main memory contents.
What power-saving modes does M30042040108X0ISAR offer?
The M30042040108X0ISAR provides two ultra-low-power states: Deep Power Down (IDPD ≤10µA) and Hibernate (IHBN ≤15µA). Both retain full memory and register contents, resume in ≤450µs, and require no reinitialization-enabling energy-efficient operation in battery-backed or intermittently powered industrial sensors and portable medical equipment.
Is M30042040108X0ISAR pin-compatible with standard SPI NOR flash devices?
The M30042040108X0ISAR uses an industry-standard 8-pin SOIC package with identical pinout (CS#, WP#/IO[2], SI/IO[0], CLK, IO[3], SO/IO[1], VCC, VSS) to common SPI NOR flash devices. While electrical timing and command sets differ, the physical footprint allows direct PCB replacement in many legacy designs-subject to firmware driver updates for MRAM-specific instructions and protection registers.
