Product details
Overview
M10042040108X0PWAY from Renesas is a 4Mbit serial STT-MRAM non-volatile memory with QSPI interface, 108MHz SDR clock speed, 1.71–2.0V supply, and industrial-plus temperature range (−40°C to +105°C). It delivers SRAM-compatible read/write timing, zero write latency, and persistent data retention-ideal for real-time data logging in factory automation controllers.
For engineers reviewing the M10042040108X0PWAY datasheet, M10042040108X0PWAY pinout, M10042040108X0PWAY application, or M10042040108X0PWAY 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 in SDR mode.
Technical Context
The M10042040108X0PWAY implements a 40nm pMTJ spin-transfer torque MRAM core with true random access, enabling byte-level reads/writes without erase cycles. Its QSPI interface supports 1-4-4 command-address-data nomenclature and executes instructions on rising clock edges in SDR mode.
It integrates dual power domains (1.8V core/I/O), hardware write protection via WP# pin, software-configurable block protection (BP[2:0]), and two low-power states-Deep Power Down (3µs entry, 400µs exit) and Hibernate (3µs entry, 450µs exit)-with full configuration retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 4 Mbit (512 KB); enables compact firmware storage and parameter logging without flash wear-out. |
| Interface | QSPI (1-4-4), SPI Mode 0/3; supports high-speed 108MHz SDR transfers with minimal host driver overhead. |
| Operating Voltage | 1.71 V – 2.00 V; compatible with modern 1.8V logic systems and reduces system-level power conversion complexity. |
| Temperature Range | −40°C to +105°C (Industrial Plus); qualified for under-hood automotive ECUs and industrial edge gateways. |
| Endurance & Retention | Virtually unlimited write cycles (>10¹⁵) and >20-year data retention at 105°C; eliminates refresh or wear-leveling firmware. |
| Package | 8-pad DFN (WSON), 5.0 mm × 6.0 mm; surface-mount compatible with standard reflow profiles and space-constrained PCB layouts. |
| Write Protection | Hardware (WP# pin) + software (Status Register BP[2:0], TBSEL); prevents accidental overwrites during power transients or firmware faults. |
Pinout & Package
Package: 8-pad DFN (WSON), 5.0 mm × 6.0 mm, exposed thermal pad (not electrically connected), RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable; device enters standby when high, tri-states outputs and halts internal operations. |
| WP# / IO[2] | Bidirectional I/O / Write Protect | In SPI mode: hardware write protect for status register; in QPI mode: bidirectional data line for quad transfers. |
| SI / IO[0] | Input / Bidirectional Data 0 | In SPI: serial input only; in QPI: bidirectional data lane 0 for command/address/data transfer. |
| CLK | Clock Input | Synchronous timing reference; latches command/address on rising edge in SDR mode; supports up to 108MHz frequency. |
| IO[3] | Bidirectional Data 3 | QPI-only data lane; enables 4-lane parallel transfers for high-throughput burst reads/writes. |
| SO / IO[1] | Output / Bidirectional Data 1 | In SPI: serial output only (data driven on falling edge); in QPI: bidirectional data lane 1. |
| VCC | Power Supply | 1.71–2.00 V core and I/O supply; requires local 100nF decoupling per datasheet recommendation. |
| VSS | Ground | Reference return path for all internal circuits and I/O drivers; must be low-impedance connection to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| eXecute-In-Place (XIP) | Enables continuous instruction execution from MRAM without repeated command loading-reduces random access latency by ~30% vs. standard SPI reads. |
| Augmented Storage Array | 256-byte user-programmable section with per-section write protection; ideal for storing calibration data, MAC addresses, or secure keys independent of main memory. |
| JEDEC Reset Support | Standardized reset command (66h) ensures interoperability with existing SPI memory controllers and simplifies firmware abstraction layers. |
| Unique & Programmable IDs | 64-bit factory-unique ID + 64-bit user-programmable serial number; enables device traceability and secure provisioning in production lines. |
| Low-Power States | Deep Power Down (IDPD < 1 µA) and Hibernate (IHBN < 5 µA); retains full configuration and memory contents while cutting quiescent current by >99%. |

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 operation (2.7–3.6V); 40MHz max SPI clock; no QSPI or XIP support. | Limited to lower-speed control applications; lacks quad interface and execute-in-place capability. | Select for cost-sensitive designs where 108MHz bandwidth and QPI are unnecessary. |
| Infineon Technologies CY14B104N-ZSP25XI | 4Mb nvSRAM; 3.0V operation; built-in lithium battery backup; 55ns async access; no serial interface. | Requires board-level battery management and larger footprint; incompatible with SPI-based host architectures. | Select only when ultra-low latency (<100ns) parallel access is mandatory and battery maintenance is acceptable. |
Compared with FM25V04-G and CY14B104N-ZSP25XI, the M10042040108X0PWAY uniquely combines 108MHz QSPI throughput, 1.8V operation, industrial-plus temperature rating, and zero-write-latency persistence-making it optimal for next-generation embedded systems demanding both speed and reliability without backup components.

FAQ
What is the operating voltage range for M10042040108X0PWAY?
The M10042040108X0PWAY operates from 1.71 V to 2.00 V. This 1.8V nominal supply range is optimized for compatibility with modern low-power microcontrollers and FPGA I/O banks. Operation outside this range may result in undefined behavior or data corruption, and the device is not rated for 3.0V operation-unlike some other members of the Mxxxx204 family.
Does M10042040108X0PWAY support Quad SPI (QPI) mode?
Yes, the M10042040108X0PWAY fully supports Quad SPI (QPI) mode using the 4-4-4 command-address-data protocol. In QPI mode, IO[3:0] pins carry all traffic, enabling 4x bandwidth versus standard SPI. The device also supports Dual SPI and Single SPI modes, with automatic mode detection based on the initial instruction sequence.
What is the significance of the '0P' suffix in M10042040108X0PWAY?
The '0P' in M10042040108X0PWAY denotes the Industrial Plus temperature grade (−40°C to +105°C), qualifying the device for extended thermal operation in demanding environments such as motor drives, power converters, and outdoor industrial gateways. This differs from the '0I' variant, which is rated only to +85°C.
How does the Augmented Storage Array function in M10042040108X0PWAY?
The M10042040108X0PWAY includes a dedicated 256-byte Augmented Storage Array, mapped to addresses 000000h–0000FFh. It is divided into eight 32-byte sections, each independently programmable and write-protectable via configuration registers-ideal for storing cryptographic keys, calibration data, or device-specific identifiers separate from main memory.
Is M10042040108X0PWAY pin-compatible with other devices in the Mxxxx204 family?
Yes, the M10042040108X0PWAY shares identical pinout and package (8-pad DFN WSON) with all Mxxxx204 variants-including M10082040108X0PWAY and M10162040108X0PWAY. This allows direct density upgrades on the same PCB layout, provided firmware accommodates the expanded address space and configuration register settings.
