Product details
Overview
M10042040054X0PWAY from Renesas is a 4Mb serial STT-MRAM non-volatile memory IC with Quad SPI interface, 54MHz DDR timing, industrial-plus temperature rating (−40°C to +105°C), and 8-pad DFN (WSON) package. It delivers SRAM-compatible random read/write performance with persistent data retention, targeting real-time data logging in factory automation controllers.
For engineers reviewing the M10042040054X0PWAY datasheet, M10042040054X0PWAY pinout, M10042040054X0PWAY application, or M10042040054X0PWAY equivalent, key selection criteria include its 1.71–2.0V/2.7–3.6V dual-voltage support, hardware/software write protection, 256-byte augmented storage array, and JEDEC Reset compliance - all critical for industrial embedded systems requiring deterministic non-volatility.
Technical Context
The M10042040054X0PWAY implements a 40nm pMTJ spin-transfer torque MRAM core with Quad SPI (4-4-4) interface supporting both SDR and DDR modes. Its architecture includes dedicated command/address/data paths, on-die voltage regulation, and dual low-power states (Deep Power Down and Hibernate) with full configuration retention.
It features a 24-bit address space mapping 4Mb (0x000000–0x07FFFF), a separate 256-byte Augmented Storage Array with per-section write protection, and register-based control of block protection (BPSEL[2:0]), top/bottom selection (TBSEL), and WP# enable (WP#EN) - enabling fine-grained data security without external logic.
Key Specifications

| 3: SI / IO[0] | Serial Input / Bidirectional Data 0 | Command/address/data input in SPI mode; bidirectional in DPI/QPI; no internal pull-up |
| 4: CLK | Clock Input | Synchronous timing source; rising edge latches command in DDR/SDR; both edges used for data in DDR |
| 5: IO[3] | Bidirectional Data 3 | Quad-mode data path; must be tied to VCC if unused in lower-pin-count configurations |
| 6: SO / IO[1] | Serial Output / Bidirectional Data 1 | Data output in SPI mode; bidirectional in DPI/QPI; always drives on falling clock edge (SDR & DDR) |
| 7: VCC | Power Supply | Core and I/O supply; requires local 100nF decoupling; supports 1.8V or 3.0V nominal rails |
| 8: VSS | Ground | Common reference for core and I/O; low-inductance connection required for noise immunity |
Key Features

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; 1.8V only; max 40MHz SPI; no DDR mode; no Augmented Storage Array | Limited to 1.8V systems; lacks quad I/O and hibernate mode; lower endurance than MRAM but faster single-byte writes | Select for cost-sensitive 1.8V-only designs where DDR bandwidth and extended temp range are not required |
| Infineon Technologies CY14B104N-ZSP25XI | 4Mb nvSRAM; 3V only; parallel interface; built-in lithium battery backup; no SPI interface | Requires PCB space for backup battery; incompatible with SPI-based microcontrollers; higher board-level BOM cost | Select only when legacy parallel bus architecture exists and battery-backed retention is mandated by system spec |
Compared with FM25V04-G and CY14B104N-ZSP25XI, the M10042040054X0PWAY provides broader voltage flexibility (1.8V/3.0V), higher bandwidth via DDR Quad SPI, integrated hibernate mode, and a dedicated 256-byte protected storage region - making it optimal for new industrial designs prioritizing compactness, thermal robustness, and firmware security.

FAQ
What is the operating voltage range supported by the M10042040054X0PWAY?
The M10042040054X0PWAY supports two independent voltage ranges: 1.71V to 2.00V and 2.70V to 3.60V. This dual-rail capability allows direct integration into both 1.8V and 3.3V system designs without level-shifting circuitry. The device automatically adapts to the applied VCC and maintains full functionality across either range, as verified in Renesas' Electrical Specifications table (Page 39).
Does the M10042040054X0PWAY require an external backup power source?
No, the M10042040054X0PWAY does not require any external backup power source. Its STT-MRAM technology provides true non-volatility: data is retained indefinitely upon power removal, with >20-year retention at 105°C. Unlike nvSRAM or battery-backed SRAM, the M10042040054X0PWAY eliminates batteries, supercapacitors, and associated failure modes while maintaining SRAM-like write performance.
How is write protection implemented on the M10042040054X0PWAY?
The M10042040054X0PWAY implements dual-layer write protection: hardware-based via the WP# pin (active-low, disables status register writes when asserted), and software-based via configuration bits in the Status Register (WP#EN, BPSEL[2:0], TBSEL). These controls independently protect the main memory array and the 256-byte Augmented Storage Array, allowing granular security without external components.
What package type is used for the M10042040054X0PWAY?
The M10042040054X0PWAY uses an 8-pad DFN (WSON) package measuring 5.0mm × 6.0mm. This small-footprint, leadless package features wettable flanks for reliable solder-joint inspection and is RoHS/REACH compliant. Pinout matches industry-standard 8-pin SOIC for layout compatibility, though the physical form factor differs.
Can the M10042040054X0PWAY operate in Deep Power Down mode while preserving configuration data?
Yes, the M10042040054X0PWAY retains all register configurations, memory contents, and Augmented Storage Array data during Deep Power Down mode. Entry requires the EDP command (B9h); exit uses EXDPD (ABh). Total wake-up time is ≤400µs (tEXDPD), and current draw drops below 1µA - enabling ultra-low-power operation in battery-powered industrial sensors without data loss or reinitialization.
