Product details
Overview
M10082040108X0PWAR from Renesas is an 8Mb serial STT-MRAM non-volatile memory IC with QSPI interface, 108MHz SDR operation, 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 without backup power-ideal for real-time industrial control logging.
For engineers reviewing the M10082040108X0PWAR datasheet, M10082040108X0PWAR pinout, M10082040108X0PWAR application, or M10082040108X0PWAR equivalent, this page provides verified specifications, package mapping, functional pin roles, JEDEC-compliant reset support, hardware/software write protection, and 256-byte augmented storage array details essential for deterministic embedded data logging and firmware parameter storage.
Technical Context
The M10082040108X0PWAR implements a 40nm pMTJ STT-MRAM array with QSPI (4-4-4) interface supporting both SDR (108MHz) and DDR (54MHz) modes. Its architecture includes dedicated command/address/data I/O routing per mode, eXecute-In-Place (XIP) capability to eliminate per-access command overhead, and dual-power-state management (Deep Power Down, Hibernate) with full configuration retention.
It integrates hardware-based write protection via WP# pin and software-based protection through configurable status and block-protection bits. The device features a separate 256-byte Augmented Storage Array-divided into eight 32-byte programmable/protectable sections-and supports JEDEC-standard reset, unique 64-bit ID, and user-programmable 64-bit serial number.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 8Mbit (1,048,576 × 8-bit organization); enables compact firmware parameter storage without external EEPROM or battery-backed SRAM. |
| Interface | QSPI (4-4-4) with SDR up to 108MHz; achieves 432MB/s effective throughput and eliminates instruction reissuing in XIP mode for deterministic code execution. |
| Supply Voltage | 1.71V–2.00V; compatible with modern low-voltage microcontroller I/O domains and reduces system-level power conversion complexity. |
| Operating Temp | −40°C to +105°C (Industrial Plus); qualified for under-hood automotive ECUs, factory-floor PLCs, and medical imaging subsystems. |
| Endurance & Retention | Virtually unlimited write cycles (>10¹⁵) and >20-year data retention at 105°C; eliminates wear leveling firmware and guarantees data integrity across product lifetime. |
| Package | 8-pad DFN (WSON), 5.0mm × 6.0mm; surface-mount footprint matches industry-standard SOIC-8 but with 30% smaller area and improved thermal performance. |
| Data Protection | Hardware WP# pin + software-configurable top/bottom/block protection; enables secure boot parameter locking and field-upgrade safeguarding. |
Pinout & Package
8-pad DFN (WSON) package, 5.0mm × 6.0mm, moisture sensitivity level 3, RoHS & REACH compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable signal; falling edge initiates instruction latch; high state forces tri-state outputs and standby current (ISB). |
| WP# / IO[2] | Bidirectional I/O / Write Protect | In SPI mode: hardware write protect for status register when enabled; in QPI mode: bidirectional data line for quad transfers. |
| SI / IO[0] | Input / Bidirectional Data 0 | In SPI: serial input only; in DPI/QPI: bidirectional data lane 0; requires external pull-up if unused in SPI mode. |
| CLK | Clock Input | Synchronous timing reference; rising edge latches commands in all modes; both edges used for address/data in DDR. |
| IO[3] | Bidirectional Data 3 | Quad-mode data lane; must be tied to VCC if unused in SPI/Dual modes to prevent floating inputs. |
| SO / IO[1] | Output / Bidirectional Data 1 | In SPI: serial output only (data valid on falling clock edge); in QPI: bidirectional data lane 1. |
| VCC | Power Supply | Single 1.71–2.0V supply powers core, I/O, and internal regulator; decoupling capacitor required adjacent to pin. |
| VSS | Ground | Common return path for core and I/O; must be low-impedance connection to minimize noise coupling into MRAM array. |
Key Features
| Feature | Design Value |
|---|---|
| eXecute-In-Place (XIP) | Enables continuous read sequences without repeated command issuance-reduces random access latency by ≥40% vs standard SPI flash. |
| Augmented Storage Array | 256-byte user-programmable space, partitioned into eight 32-byte sections, each independently write-protectable for secure calibration data. |
| JEDEC Reset Support | Standardized reset command (66h) restores default configuration without requiring power cycle-critical for remote firmware recovery. |
| Unique & Programmable IDs | Factory-assigned 64-bit UID + user-writable 64-bit serial number; enables device traceability, secure provisioning, and anti-counterfeiting. |
| Low-Power States | Deep Power Down (IDPD ≤ 2µA) and Hibernate (IHBN ≤ 10µA) retain full configuration and memory contents-supports energy-constrained edge nodes. |

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 FM25V08-G | 8Mb F-RAM; 3.0V supply (2.7–3.6V); max 40MHz SPI; no QPI or XIP support. | Limited to lower-speed control interfaces; lacks quad mode and execute-in-place-unsuitable for high-throughput firmware execution. | Select only if 3.3V system integration and <40MHz bandwidth suffice; avoid for 108MHz deterministic timing or XIP-critical designs. |
| Infineon Technologies CY14V108N-ZSP25XI | 8Mb nvSRAM; 2.7–3.6V supply; built-in lithium battery backup; 25ns async access; no serial interface. | Requires PCB space for backup battery and voltage monitoring; incompatible with SPI-only host controllers. | Choose only for legacy parallel-bus systems needing nanosecond random access; not viable for modern QSPI-based SoC platforms. |
Compared with FM25V08-G and CY14V108N-ZSP25XI, the M10082040108X0PWAR uniquely combines 108MHz QSPI speed, XIP capability, 1.8V operation, and zero-battery non-volatility-making it the only option for compact, high-reliability, battery-free embedded systems demanding both speed and persistence.

FAQ
What is the operating voltage range for the M10082040108X0PWAR?
The M10082040108X0PWAR operates from 1.71V to 2.00V. This 1.8V nominal supply range is optimized for compatibility with modern low-power microcontrollers and eliminates the need for level-shifting circuitry. Operation outside this range may result in undefined behavior or data corruption, and the device is not rated for 3.3V operation-using M10082040108X0PWAR at 3.0V violates its absolute maximum ratings.
Does the M10082040108X0PWAR support Quad SPI (QPI) mode?
Yes, the M10082040108X0PWAR fully supports Quad SPI (4-4-4) mode with 108MHz SDR timing. In QPI mode, all four I/O pins (IO[0]–IO[3]) carry command, address, and data simultaneously-enabling 432MB/s effective bandwidth. The device also supports Dual SPI and standard Single SPI, with mode selection controlled via configuration registers and instruction opcodes defined in the datasheet.
How does the Augmented Storage Array function in the M10082040108X0PWAR?
The M10082040108X0PWAR 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 bits. This array is ideal for storing calibration data, device-specific parameters, or secure keys-separate from main memory and protected against accidental overwrite.
What is the endurance specification of the M10082040108X0PWAR?
The M10082040108X0PWAR guarantees virtually unlimited endurance-exceeding 10¹⁵ write cycles-due to its spin-transfer torque magnetoresistive (STT-MRAM) technology. Unlike flash or EEPROM, it exhibits no wear-out mechanism, eliminating the need for wear leveling algorithms or block management firmware. Data retention exceeds 20 years at +105°C, validated per JEDEC JESD22-A117.
Is the M10082040108X0PWAR pin-compatible with other members of the Mxxxx204 family?
Yes, the M10082040108X0PWAR shares identical pinout, package dimensions, and electrical interface with all Mxxxx204 variants-including M1004204 and M1016204-in both 8-pad DFN and 8-pin SOIC packages. Density and speed differences are handled entirely within the command set and timing parameters; no PCB redesign is needed when scaling capacity or performance within the same package type.
