Product details
Overview
M10162040108X0IWAR from Renesas is a 16Mbit serial STT-MRAM non-volatile memory IC with QSPI interface, 108MHz SDR clock speed, 1.71–2.0V supply voltage, and industrial temperature range (−40°C to +85°C). It delivers SRAM-compatible read/write timing, zero write latency, and persistent data retention without backup power-used in real-time industrial control logging and firmware storage.
For engineers reviewing the M10162040108X0IWAR datasheet, M10162040108X0IWAR pinout, M10162040108X0IWAR application, or M10162040108X0IWAR equivalent, key selection criteria include QSPI x4 interface compatibility, 108MHz SDR timing compliance, WSON-8 package footprint, hardware/software write protection, and 16Mbit density for deterministic boot code storage.
Technical Context
The M10162040108X0IWAR implements a 40nm pMTJ spin-transfer torque MRAM array with quad SPI (QPI) command-address-data (4-4-4) support and Execute-In-Place (XIP) capability. Its architecture enables single-cycle random reads/writes without erase cycles, eliminating write latency penalties inherent in Flash.
It integrates dual protection mechanisms: hardware write protect via WP# pin and software-configurable block protection through Status and Configuration Registers. The device supports Deep Power Down (3µs entry, 400µs exit) and Hibernate modes while retaining full configuration state and memory contents.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 16 Mbit (2 MByte) main memory array - sufficient for full firmware images or real-time data buffers in edge controllers |
| Interface | Quad SPI (QPI) 4-4-4 mode - enables 432 MB/s peak throughput at 108 MHz SDR, matching high-speed microcontroller bus requirements |
| Supply Voltage | 1.71 V – 2.00 V - compatible with modern low-voltage SoCs and eliminates need for level-shifting in 1.8V systems |
| Operating Temp | −40°C to +85°C - certified for industrial automation environments including PLC backplanes and motor drives |
| Endurance | Virtually unlimited (>10¹⁵ cycles) - eliminates wear-leveling firmware overhead and guarantees lifetime data integrity |
| Data Retention | 20+ years at 85°C - ensures unpowered data persistence across equipment maintenance cycles and field deployments |
| Package | 8-pad DFN (WSON), 5.0 mm × 6.0 mm - surface-mount compatible with automated assembly and thermal performance validated per JEDEC JESD51-2 |
Pinout & Package
8-pad DFN (WSON) package, 5.0 mm × 6.0 mm body, 0.5 mm pitch, exposed thermal pad (EP), RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable signal; falling edge initiates instruction latch; must be held stable during power-up per tPU = 250 µs requirement |
| WP# / IO[2] | Bidirectional I/O / Hardware Write Protect | In SPI mode: input-only write protect; in QPI mode: bidirectional data line; requires external pull-up if unused |
| SI / IO[0] | Serial Input / Bidirectional Data 0 | Command/address/data input in SDR; primary I/O in 1-1-1/1-1-4 modes; latched on rising CLK edge |
| CLK | Clock Input | Synchronous timing reference; supports SPI Mode 0 (CPOL=0, CPHA=0); 108 MHz max frequency in SDR |
| IO[3] | Bidirectional Data 3 | QPI data lane; used for address/data in 4-4-4 mode; must be tied to VCC if not used in lower-pin-count configurations |
| SO / IO[1] | Serial Output / Bidirectional Data 1 | Data output in SDR begins on falling CLK edge; bidirectional in QPI; high-impedance when CS# high |
| VCC | Power Supply | 1.71–2.00 V core/I/O rail; requires local 100 nF ceramic decoupling per datasheet layout guidelines |
| VSS | Ground | Common reference for all signals; connected to exposed thermal pad for thermal and EMI performance |
Key Features
| Feature | Design Value |
|---|---|
| SRAM-compatible timing | No erase cycles or write latency; random read/write access time ≤ 8 ns - enables direct replacement of PSRAM in boot memory subsystems |
| Hardware + software write protection | WP# pin + Status Register BPSEL bits allow hierarchical locking of top/bottom memory blocks - prevents accidental firmware corruption during field updates |
| 256-byte Augmented Storage Array | User-programmable, section-wise write-protectable space for calibration data or secure keys - independent of main array and retained across power cycles |
| JEDEC Reset support | Standard reset command (66h) restores default register states - simplifies system initialization and avoids post-reflow reprogramming |
| Deep Power Down mode | Reduces ICC to <1 µA while preserving memory and register contents - extends battery life in always-on industrial sensors |

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 FM16W08 | 8 Mbit FRAM, 1.8V, 40 MHz SPI - lower density, slower interface, no QPI or XIP support | Limited to smaller firmware footprints; lacks deep power down and augmented storage array | Select when legacy SPI-1-1-1 interface suffices and 8 Mbit capacity meets design constraints |
| Infineon Technologies CY14B108N | 8 Mbit nvSRAM, 3.3V, 100 MHz parallel interface - different bus architecture, higher voltage, larger SOIC-28 package | Requires PCB redesign for parallel bus routing and level translation; incompatible with QSPI-based host SoCs | Choose only for drop-in replacement in existing parallel-memory designs where board rework is acceptable |
Compared with FM16W08 and CY14B108N, the M10162040108X0IWAR provides double the density, 108 MHz QPI bandwidth, and WSON-8 footprint - enabling higher-performance, space-constrained industrial edge nodes without compromising data persistence or power efficiency.

FAQ
What is the maximum clock frequency supported by M10162040108X0IWAR in Single Data Rate mode?
The M10162040108X0IWAR supports up to 108 MHz in Single Data Rate (SDR) mode. This is specified in the ordering code "0108" and confirmed in the Features section of the datasheet. At this frequency, command, address, and data are latched on the rising edge of CLK for inputs and output on the falling edge - enabling deterministic timing for real-time microcontroller interfaces.
Does M10162040108X0IWAR require an external voltage regulator for its 1.8V supply?
No, the M10162040108X0IWAR operates directly from a 1.71 V to 2.00 V supply and does not require an external regulator if the system already provides a stable 1.8V rail. However, the datasheet mandates local 100 nF ceramic decoupling at the VCC pin to suppress switching noise and ensure reliable operation at 108 MHz.
Can M10162040108X0IWAR be used as a direct replacement for standard SPI NOR Flash in existing designs?
Yes, the M10162040108X0IWAR is pin-compatible with industry-standard 8-pin SOIC and WSON-8 SPI NOR Flash devices and supports identical instruction sets (e.g., Read, Write Enable, Page Program). However, it eliminates erase commands and offers faster random writes - requiring only minor firmware updates to remove erase routines and leverage its true byte-write capability.
How is write protection implemented on M10162040108X0IWAR?
M10162040108X0IWAR implements dual-layer write protection: hardware-based via the WP# pin (active-low, disables Status Register writes when enabled), and software-based via BPSEL bits in the Status Register that configure top/bottom block protection. Both mechanisms can be used simultaneously to safeguard critical firmware regions against accidental overwrites during field updates.
What is the purpose of the Augmented Storage Array in M10162040108X0IWAR?
The Augmented Storage Array is a dedicated 256-byte user-programmable memory region divided into eight 32-byte sections. Each section can be individually write-protected. It is intended for storing calibration data, security keys, or device-specific identifiers - isolated from the main 16 Mbit array to prevent corruption during bulk firmware updates and retained across all power states including Deep Power Down.
