Product details
Overview
M10082040108X0PSAR from Renesas is an 8Mb serial STT-MRAM (Spin-Transfer Torque Magnetoresistive RAM) memory IC with QSPI interface, 108MHz SDR clock rate, 1.71–2.0V or 2.7–3.6V supply, and industrial-plus temperature range (−40°C to +105°C). It delivers SRAM-compatible read/write timing with true non-volatility, used in real-time data logging and firmware storage for industrial controllers.
For engineers reviewing the M10082040108X0PSAR datasheet, M10082040108X0PSAR pinout, M10082040108X0PSAR application, or M10082040108X0PSAR equivalent, key selection criteria include QSPI x4 interface support, hardware/software write protection, 256-byte augmented storage array, JEDEC reset compliance, and dual-voltage operation across extended temperature.
Technical Context
The M10082040108X0PSAR implements a 40nm pMTJ STT-MRAM cell architecture enabling persistent SRAM behavior with no wear-out mechanism. Its command-address-data nomenclature supports 1-4-4 QPI mode using all four I/O pins for address and data transfer, synchronized by rising-edge clock sampling in SDR mode.
It integrates dedicated registers for status control, configuration (four registers), device identification (64-bit unique ID), and user-programmable serial number. Power management includes Deep Power Down (3µs entry, 400µs exit) and Hibernate modes, both preserving data and register state without external refresh.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 8 megabit (1,048,576 × 8-bit organization); enables compact firmware storage without external ECC logic |
| Interface | Quad SPI (QPI, 4-4-4 mode); allows 4x bandwidth vs standard SPI, reducing instruction overhead in XIP applications |
| Max Clock Rate | 108 MHz SDR; achieves ~43 MB/s effective read throughput in QPI mode with continuous burst |
| Supply Voltage | 1.71–2.00 V or 2.70–3.60 V; dual-range support simplifies integration into mixed-voltage industrial PCBs |
| Operating Temp | −40°C to +105°C (industrial plus); qualified for under-hood automotive ECUs and factory-floor PLCs |
| Endurance | Virtually unlimited write cycles (>10¹⁵); eliminates lifetime concerns in high-frequency logging or parameter update scenarios |
| Data Retention | 20+ years at +105°C; ensures firmware integrity over full product lifecycle without backup power |
Pinout & Package
Package: 8-pin SOIC (5.2 mm × 5.2 mm), RoHS-compliant, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable; falling edge initiates instruction sequence; must be held low during command/address/data transfer |
| WP# / IO[2] | Bidirectional I/O or Hardware Write Protect | In SPI mode: hardware lock for status register when WP# = Low and SR[7] = 1; in QPI mode: bidirectional data line |
| SI / IO[0] | Serial Input or Quad Data 0 | Command input in 1-1-1/1-1-4; primary data-in path in single/dual/quad modes |
| CLK | Clock Input | Synchronous timing reference; rising edge latches command/address in SDR; both edges used in DDR |
| IO[3] | Quad Data 3 | Used only in Dual/Quad modes; tied to VCC if unused to prevent floating |
| SO / IO[1] | Serial Output or Quad Data 1 | Data output in 1-1-1/1-1-4; always outputs on falling clock edge per spec |
| VCC | Power Supply | Single supply for core and I/O; supports 1.8V or 3.3V rails; requires local decoupling |
| VSS | Ground | Common return path; must be low-impedance connection to minimize noise coupling into MRAM array |
Key Features
| Feature | Design Value |
|---|---|
| eXecute-In-Place (XIP) | Enables direct code execution from MRAM without copying to RAM; reduces boot latency and external memory footprint |
| Augmented Storage Array | 256-byte user-programmable space with per-section (32B) write protection; ideal for calibration data or secure keys |
| Hardware + Software Protection | WP# pin + configurable block protect bits (BPSEL[2:0]) + top/bottom select (TBSEL) provide layered security against accidental writes |
| JEDEC Reset Support | Standardized reset command (66h) ensures interoperability with host bootloaders and memory controllers compliant with JEDEC JESD252 |
| Deep Power Down Mode | Reduces current to <1 µA while retaining full memory content and register state; suitable for battery-backed sleep states |

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; 40MHz SPI max; 2.0–3.6V supply; no QPI mode; lower endurance (~10¹⁴ cycles) | Limited to lower-bandwidth logging; lacks XIP and augmented storage; simpler protection model | Select when cost sensitivity outweighs speed and feature requirements; verify timing margins for legacy SPI hosts |
| Infineon Technologies CY14V108N-ZSP25XI | 8Mb nvSRAM; 25MHz parallel interface; 3.3V only; requires external capacitor for store operation | Not serial; higher pin count; store/retrieve latency depends on capacitor charge time | Choose only if existing design uses parallel bus; avoid for new QSPI-based platforms due to interface mismatch |
Compared with FM25V08-G and CY14V108N-ZSP25XI, the M10082040108X0PSAR provides superior bandwidth via QPI, eliminates external energy storage components, and adds programmable augmented storage-making it optimal for next-generation industrial and medical edge devices requiring fast, reliable, and secure non-volatile memory.

FAQ
What is the exact memory density and organization of M10082040108X0PSAR?
M10082040108X0PSAR is an 8-megabit serial MRAM with a 1,048,576 × 8-bit organization. Its 24-bit addressing supports the full 000000h–0FFFFFh range. This density balances compact footprint with sufficient capacity for firmware images, configuration tables, and real-time data buffers in resource-constrained embedded systems.
Does M10082040108X0PSAR support both 1.8V and 3.3V operation?
Yes, M10082040108X0PSAR supports two independent supply ranges: 1.71–2.00 V and 2.70–3.60 V. The device auto-detects voltage level and configures internal regulators accordingly. No external level-shifting circuitry is required, simplifying design for mixed-voltage boards where M10082040108X0PSAR interfaces with 1.8V MCUs or 3.3V FPGAs.
How does the Augmented Storage Array in M10082040108X0PSAR differ from main memory?
The Augmented Storage Array in M10082040108X0PSAR is a separate 256-byte region divided into eight 32-byte sections, each independently programmable and write-protectable via configuration bits. Unlike main memory, it's intended for critical calibration data or security keys-offering finer-grained protection without affecting firmware storage in the primary 8Mb array.
Is M10082040108X0PSAR pin-compatible with other members of the Mxxxx204 family?
Yes, all Mxxxx204 variants-including M1004204, M1008204, and M1016204-in 8-pin SOIC or 8-pad DFN packages share identical pinouts and electrical characteristics. This allows drop-in replacement across densities (4Mb/8Mb/16Mb) and speed grades (108MHz/54MHz), provided timing and voltage requirements are met in the target application.
What power-saving modes does M10082040108X0PSAR offer, and how quickly can it resume operation?
M10082040108X0PSAR offers Deep Power Down (IDPD) and Hibernate modes. Both retain full memory and register contents. Entry takes ≤3 µs; exit from Deep Power Down requires ≤400 µs, and from Hibernate ≤450 µs. These modes reduce active current to <1 µA, making M10082040108X0PSAR suitable for battery-powered edge nodes with strict energy budgets.
