Product details
Overview
M10082040054X0PWAR from Renesas is an 8Mb serial STT-MRAM non-volatile memory IC with QSPI interface, 54MHz DDR timing, industrial-plus temperature rating (−40°C to +105°C), and 1.71–2.0V or 2.7–3.6V dual-voltage operation. It delivers SRAM-compatible read/write latency, unlimited endurance, and data retention for real-time data logging in factory automation controllers.
For engineers reviewing the M10082040054X0PWAR datasheet, M10082040054X0PWAR pinout, M10082040054X0PWAR application, or M10082040054X0PWAR equivalent, key selection criteria include its 8-pad DFN (WSON) package, hardware/software write protection, 256-byte augmented storage array, JEDEC reset support, and compatibility with SPI Mode 0/3 across SDR/DDR modes.
Technical Context
The M10082040054X0PWAR implements a 40nm pMTJ spin-transfer torque MRAM core with quad-SPI (4-4-4) interface supporting both Single Data Rate (SDR) and Double Data Rate (DDR) protocols. Its architecture includes dedicated command/address/data paths, on-die voltage regulation, and independent 256-byte augmented storage array with per-section write protection.
It operates in three power states - active, standby, and low-power hibernate/deep power-down - with full configuration retention during state transitions. All instructions are executed via an 8-bit instruction register, and XIP (eXecute-In-Place) mode reduces command overhead for sequential access patterns.
Key Specifications

| VCC | Power Supply | Single supply for core and I/O; supports 1.8V or 3.3V operation with internal regulation |
| VSS | Ground | Common reference for core and I/O; requires local 100nF decoupling adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|

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 FM25V05 | 512Kb F-RAM; 40MHz SPI; 2.7–3.6V only; no DDR mode; no augmented storage array | Limited density and voltage flexibility; lower endurance than MRAM but faster write cycle time | Prefer for cost-sensitive, low-density (<1Mb), 3.3V-only designs where ultra-fast single-byte writes dominate |
| Infineon Technologies CY14V108N | 8Mb nvSRAM; 100MHz parallel interface; requires external VCAP capacitor; 3.3V only | Parallel bus increases PCB routing complexity and pin count; capacitor dependency adds BOM cost and reliability risk | Prefer only when legacy parallel interface is mandated and board space allows VCAP placement |
Compared with FM25V05 and CY14V108N, the M10082040054X0PWAR offers higher density in serial form factor, dual-voltage operation, DDR timing headroom, and integrated hardware/software protection - making it optimal for new industrial designs prioritizing footprint, flexibility, and long-term data integrity.

FAQ
What is the operating voltage range supported by the M10082040054X0PWAR?
The M10082040054X0PWAR supports two distinct VCC ranges: 1.71V to 2.00V for 1.8V systems, and 2.70V to 3.60V for 3.3V systems. It does not operate across the entire 1.71–3.60V span - users must select one voltage domain during design and ensure stable rail regulation within the chosen range. Both ranges are fully specified for all performance parameters including 54MHz DDR timing and −40°C to +105°C operation.
Does the M10082040054X0PWAR require an external capacitor for non-volatility like nvSRAM devices?
No, the M10082040054X0PWAR does not require any external capacitor. As a true MRAM device, it retains data inherently through magnetic tunnel junctions - eliminating the need for backup capacitors, batteries, or charge pumps. This simplifies BOM, improves long-term reliability, and removes capacitor aging and leakage concerns present in nvSRAM solutions such as the CY14V108N.
How is write protection implemented on the M10082040054X0PWAR?
The M10082040054X0PWAR implements dual-layer write protection: hardware-based via the WP# pin (active-low, disables status register writes when enabled), and software-based via configuration bits in the Status Register (BPSEL[2:0], TBSEL, SNPEN). These mechanisms can be used independently or concurrently to protect main memory, augmented storage array, and serial number registers against accidental or malicious modification.
What package type is used for the M10082040054X0PWAR, and is it pin-compatible with other serial memories?
The M10082040054X0PWAR uses an 8-pad DFN (WSON) package measuring 5.0mm × 6.0mm with 0.5mm pitch. Its pinout matches industry-standard serial NOR Flash and FRAM devices in the same footprint (e.g., SOIC-8 pin-compatible layout), enabling drop-in replacement in many existing designs - provided voltage, timing, and instruction set compatibility are verified per the datasheet.
Can the M10082040054X0PWAR be used in DDR mode at 54MHz while operating at 1.8V?
Yes, the M10082040054X0PWAR is fully specified for Double Data Rate (DDR) operation at 54MHz across both voltage ranges - including 1.71–2.00V. The 0054 performance grade in the part number explicitly denotes DDR-54MHz capability, and electrical characteristics in Tables 14–15 of the datasheet confirm timing compliance at 1.8V with tV < 9.26ns setup/hold margins under industrial-plus conditions.
