Product details
Overview
M10042040108X0PSAY from Renesas is a 4Mb serial STT-MRAM non-volatile memory IC with QSPI interface, 108MHz SDR clock speed, 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 - deployed in real-time industrial control and medical diagnostics systems requiring deterministic memory access.
For engineers reviewing the M10042040108X0PSAY datasheet, M10042040108X0PSAY pinout, M10042040108X0PSAY application, or M10042040108X0PSAY equivalent, key selection criteria include its 4Mb density, 8-pad DFN (WSON) package, hardware/software write protection, 256-byte augmented storage array, and JEDEC Reset support for robust embedded firmware storage.
Technical Context
The M10042040108X0PSAY implements a 40nm pMTJ spin-transfer torque MRAM core with quad SPI (QPI: 4-4-4) interface supporting both SDR (108MHz) and DDR (54MHz) modes. Its architecture includes dedicated command/address/data I/O lanes, on-chip high-voltage generator for write operations, and dual low-power states (Deep Power Down and Hibernate) preserving data and configuration.
It integrates a 256-byte user-programmable augmented storage array with per-section write protection, 64-bit unique ID, and 64-bit user-programmable serial number. Memory mapping uses 24-bit addressing with fixed 0x000000–0x07FFFF range for 4Mb density, and supports eXecute-In-Place (XIP) to eliminate per-access command overhead during burst reads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 4Mbit (512KB), mapped to 24-bit address space 0x000000–0x07FFFF |
| Interface | Quad SPI (QPI) with 4-4-4 command-address-data lane allocation; supports SDR up to 108MHz |
| Supply Voltage | 1.71V–2.00V - enables direct integration into 1.8V logic domains without level shifting |
| Operating Temp | −40°C to +105°C (Industrial Plus) - qualified for under-hood automotive and factory-floor environments |
| Endurance & Retention | Virtually unlimited write cycles (>10¹⁵) and >20-year data retention at 105°C - eliminates wear leveling firmware |
| Write Protection | Hardware (WP# pin) + software (Status Register BPSEL/TBSEL bits) - enables selective block-level lockdown |
| Augmented Storage | 256-byte user-programmable array, partitioned into eight 32-byte sections with individual write lock capability |
Pinout & Package
Package: 8-pad DFN (WSON), 5.0mm × 6.0mm, moisture sensitivity level (MSL) 3, RoHS/REACH compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable; falling edge initiates instruction sequence; high state places device in standby with tri-stated outputs |
| WP# / IO[2] | Bidirectional Write Protect / Quad Data Line | In SPI mode: hardware write protect for status register when WP# = Low and SR[7] = 1; in QPI mode: bidirectional data lane IO[2] |
| SI / IO[0] | Input / Bidirectional Serial Data | In SPI mode: unidirectional command/address/data input; in QPI mode: bidirectional data lane IO[0] |
| CLK | Clock Input | Synchronous timing reference; rising edge latches commands in SDR/DDR; both edges used for address/data in DDR |
| IO[3] | Bidirectional Quad Data Line | Used only in Dual/Quad SPI modes as data lane IO[3]; may be tied to VCC if unused |
| SO / IO[1] | Output / Bidirectional Serial Data | In SPI mode: unidirectional data output on falling clock edge; in QPI mode: bidirectional data lane IO[1] |
| VCC | Power Supply | Single 1.71–2.0V supply powers core, I/O, and internal regulator - no separate VIO required |
| VSS | Ground | Common return path for core and I/O; requires local 100nF decoupling adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| STT-MRAM Technology | 40nm pMTJ cell enables true random read/write with zero write latency and no erase-before-write overhead |
| eXecute-In-Place (XIP) | Eliminates repeated command transmission during sequential reads - reduces effective access time by ~30% vs standard SPI |
| Augmented Storage Array | 256-byte independent memory region with per-section write lock - ideal for storing calibration data or firmware signatures |
| JEDEC Reset Support | Standardized reset command (66h) ensures interoperability across host controllers without custom initialization sequences |
| Dual Low-Power States | Deep Power Down (IDPD) and Hibernate (IHBN) reduce current to <1µA while retaining full memory content and register state |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-volatile serial memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress Semiconductors FM25V04-G | 4Mb F-RAM; 3.0V supply (2.7–3.6V); max 40MHz SPI; no QPI or XIP support | Limited to 85°C operation; lacks augmented storage and JEDEC Reset; lower write bandwidth | Choose for legacy 3V systems where ultra-high endurance is needed but QPI/XIP not required |
| Infineon Technologies CY14V104N-ZSP25XI | 4Mb nvSRAM; 3.0V supply; built-in lithium battery backup; 25ns async parallel interface | Requires external battery and PCB footprint for backup circuitry; no serial interface; higher BOM cost | Choose only when strict 25ns random access is mandatory and board space allows battery integration |
Compared with FM25V04-G and CY14V104N-ZSP25XI, the M10042040108X0PSAY provides higher interface bandwidth (108MHz QPI vs 40MHz SPI), broader temperature range (105°C vs 85°C), and integrated features like XIP and augmented storage - reducing firmware complexity and eliminating backup components.

FAQ
What is the operating voltage range for the M10042040108X0PSAY?
The M10042040108X0PSAY operates from 1.71V to 2.00V - a tightly regulated 1.8V domain. This eliminates need for level shifters in modern low-voltage SoC designs and ensures compatibility with 1.8V I/O standards. Operation outside this range is not guaranteed, and VCC must ramp within specified tRVR limits during power-up.
Does the M10042040108X0PSAY support Quad SPI (QPI) mode?
Yes, the M10042040108X0PSAY fully supports Quad SPI (QPI) with 4-4-4 command-address-data lane allocation. In QPI mode, it achieves 108MHz SDR throughput and enables eXecute-In-Place (XIP) for accelerated code execution directly from memory - a capability not available in standard SPI-only MRAMs.
How is write protection implemented on the M10042040108X0PSAY?
The M10042040108X0PSAY implements dual-layer write protection: hardware-based via the WP# pin (active-low, requires SR[7]=1), and software-based via Status Register BPSEL[2:0] and TBSEL bits. Both mechanisms can be combined to lock specific memory blocks or the entire array - critical for safeguarding firmware and calibration data.
What is the purpose of the Augmented Storage Array in the M10042040108X0PSAY?
The M10042040108X0PSAY includes a dedicated 256-byte Augmented Storage Array, partitioned into eight 32-byte sections. Each section can be individually programmed and write-locked - making it ideal for storing device-specific identifiers, calibration offsets, or cryptographic keys that must survive firmware updates without risk of overwrite.
Is the M10042040108X0PSAY compatible with industrial-plus temperature requirements?
Yes, the M10042040108X0PSAY is rated for −40°C to +105°C operation (Industrial Plus grade). It is qualified per AEC-Q100 stress test standards for reliability in demanding environments such as factory-floor controllers, under-hood telematics, and portable medical equipment - with full specification compliance across the entire range.
