Product details
Overview
M10162040054X0PSAY from Renesas is a 16Mbit serial STT-MRAM non-volatile memory IC with QSPI interface, 54MHz DDR timing, industrial-plus temperature rating (−40°C to +105°C), and 8-pin SOIC package. It delivers SRAM-compatible read/write latency, zero write endurance limit, and data retention >20 years - deployed in real-time industrial control systems requiring deterministic, power-loss-safe data logging.
For engineers reviewing the M10162040054X0PSAY datasheet, M10162040054X0PSAY pinout, M10162040054X0PSAY application, or M10162040054X0PSAY 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 high-reliability embedded firmware and configuration storage.
Technical Context
The M10162040054X0PSAY implements a 40nm pMTJ spin-transfer torque MRAM core with quad SPI (QPI) interface supporting 1-4-4 command-address-data nomenclature. Its architecture enables eXecute-In-Place (XIP) mode to eliminate per-access command overhead, reducing random read latency versus legacy serial NOR Flash.
It integrates dual power domains (1.8V and 3.0V compatible), on-die voltage regulation, and two low-power states - Deep Power Down (IDPD ≤ 2 µA) and Hibernate (IHBN ≤ 10 µA) - both preserving full register state and memory contents without external backup power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 16 Mbit (2 MByte) main memory array with linear 24-bit addressing (0x000000–0x1FFFFF) |
| Interface | Quad SPI (QPI) 4-4-4 mode; supports DDR at 54 MHz (108 Mbps effective throughput) |
| Voltage Range | 1.71–2.00 V or 2.70–3.60 V - dual-rail compatibility enables direct replacement of 1.8V/3.3V serial Flash/NOR |
| Operating Temp | −40°C to +105°C (Industrial Plus grade) - qualified for under-hood automotive and factory-floor environments |
| Endurance | Virtually unlimited (>10¹⁵ cycles) - eliminates wear-leveling firmware and write-cycle management overhead |
| Data Retention | >20 years at +105°C - guaranteed non-volatility without refresh or backup power |
| Augmented Storage | 256-byte user-programmable array, partitioned into eight 32-byte sections with individual write protection |
Pinout & Package
Package: 8-pin SOIC (5.2 mm × 5.2 mm), RoHS-compliant, surface-mount, industrial-plus rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable; falling edge initiates instruction sequence; high = standby (tri-state I/Os, ISB current) |
| WP# / IO[2] | Write Protect / Bidirectional Data 2 | Hardware lock for status register when WP# = low + SR[7]=1; also serves as QPI data lane IO[2] |
| SI / IO[0] | Serial Input / Bidirectional Data 0 | Command/address input in SDR; bidirectional in DPI/QPI modes; no internal pull-up |
| CLK | Clock Input | Synchronous timing source; DDR uses both edges; supports SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) |
| IO[3] | Bidirectional Data 3 | QPI data lane; tied to VCC if unused in single/dual SPI configurations |
| SO / IO[1] | Serial Output / Bidirectional Data 1 | Data output begins on falling clock edge in all modes; tri-stated when CS# = high |
| VCC | Power Supply | Single supply for core and I/O; accepts 1.71–2.00 V or 2.70–3.60 V; requires local decoupling |
| VSS | Ground | Common reference for core and I/O; must be low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| eXecute-In-Place (XIP) | Enables continuous burst reads without repeated command issuance - reduces average random access time by ≥30% vs standard SPI flash |
| Hardware + Software Protection | WP# pin + configurable block protect bits (BPSEL[2:0]) and top/bottom select (TBSEL) - prevents accidental writes to firmware or calibration data |
| JEDEC Reset Support | Standardized reset command (66h) restores device to known state - simplifies system recovery after brown-out or watchdog timeout |
| Unique & Programmable IDs | 64-bit factory-unique ID + 64-bit user-writable serial number - enables secure device authentication and traceability in production |
| Deep Power Down Mode | Enters sub-2 µA quiescent current state in <3 µs; exits in <400 µs with full register and memory state preserved |

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 FM25V16-G | 16Mb F-RAM; 40 MHz SPI max; 2.7–3.6 V only; no DDR mode; 10¹⁴ endurance | Limited to 3.3V systems; lower bandwidth; no XIP or augmented storage array | Choose for legacy 3.3V designs where DDR and dual-voltage operation are unnecessary |
| Infineon Technologies CY14V108N-ZSP25XI | 8Mb nvSRAM with parallel interface; 25 ns access; 3.3 V only; requires external capacitor for store operation | Parallel bus footprint; higher pin count; capacitor-dependent non-volatility; no QSPI compatibility | Choose only when existing PCB layout mandates parallel interface and deterministic nanosecond access is required |
Compared with FM25V16-G and CY14V108N-ZSP25XI, the M10162040054X0PSAY uniquely combines QSPI DDR speed, dual-voltage operation, on-chip augmented storage, and true infinite endurance - making it the only drop-in upgrade path for 1.8V/3.3V serial Flash in industrial-plus temperature applications.

FAQ
What is the maximum clock frequency supported by M10162040054X0PSAY in Double Data Rate mode?
The M10162040054X0PSAY supports up to 54 MHz in Double Data Rate (DDR) mode, achieving an effective data rate of 108 Mbps. This is confirmed in the "Features" section of the datasheet and applies specifically to the "0054" performance grade denoted in the part number. The device does not support DDR above 54 MHz - attempting higher frequencies violates timing specifications and may cause data corruption.
Does M10162040054X0PSAY require external hardware for non-volatility, such as a backup capacitor or battery?
No, the M10162040054X0PSAY is inherently non-volatile due to its STT-MRAM technology and requires no external energy storage. Unlike nvSRAM or FRAM, it retains data indefinitely after power removal without capacitors, batteries, or supercapacitors. This eliminates associated bill-of-materials cost, board space, and reliability concerns related to backup power components.
Can M10162040054X0PSAY be used as a direct replacement for standard SPI NOR Flash in existing designs?
Yes - the M10162040054X0PSAY uses industry-standard SPI commands (including Read, Write Enable, Write Status Register, and JEDEC Reset), shares identical 8-pin SOIC pinout and timing envelopes, and supports the same 1-1-1, 1-1-4, and 4-4-4 protocols. Firmware changes are minimal: only DDR enable/disable and optional XIP activation are needed to unlock full performance.
What is the purpose and size of the Augmented Storage Array in M10162040054X0PSAY?
The M10162040054X0PSAY includes a dedicated 256-byte Augmented Storage Array, partitioned into eight 32-byte programmable sections. Each section can be individually write-protected via configuration registers. It is intended for storing infrequently modified but safety-critical data - such as calibration constants, device serial numbers, or cryptographic keys - isolated from the main memory array to prevent accidental overwrite.
Is M10162040054X0PSAY qualified for automotive applications?
The M10162040054X0PSAY is specified for Industrial Plus temperature range (−40°C to +105°C) and is commonly deployed in under-hood and chassis-mounted industrial control units. However, it is not AEC-Q100 qualified. For automotive safety-critical applications requiring formal qualification, consult Renesas' automotive-grade MRAM portfolio - the M10162040054X0PSAY is intended for industrial and medical systems with equivalent thermal and reliability demands.
