Product details
Overview
M10082040108X0IWAY from Renesas is an 8Mb 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) in 8-pad DFN (WSON) package. It delivers SRAM-compatible read/write timing with persistent data retention, enabling real-time data logging in factory automation controllers.
For engineers reviewing the M10082040108X0IWAY datasheet, M10082040108X0IWAY pinout, M10082040108X0IWAY application, or M10082040108X0IWAY equivalent, this page provides verified technical context, pin-level functional roles, JEDEC-compliant reset support, hardware/software write protection, and XIP-enabled low-latency execution for deterministic embedded storage design.
Technical Context
The M10082040108X0IWAY implements a 40nm pMTJ spin-transfer torque MRAM array with quad SPI (4-4-4) interface supporting both SDR (108MHz) and DDR (54MHz) modes. Its architecture includes dedicated command/address/data I/O lanes, on-die high-voltage generator for write operations, and dual power states-Deep Power Down (3µs entry, 400µs exit) and Hibernate (3µs entry, 450µs exit)-with full configuration retention.
It features a 256-byte Augmented Storage Array segmented into eight 32-byte programmable/protectable sections, plus 64-bit unique ID and user-programmable serial number registers. All register access occurs via dedicated SPI instruction set (e.g., RDSR at 0x05, WRSR at 0x01), with status register bits controlling WP#-enabled hardware protection and top/bottom block software protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 8Mbit (1,048,576 × 8-bit organization); supports full random read/write without erase cycles. |
| Interface | Quad SPI (4-4-4) with JEDEC Reset; enables XIP mode to eliminate per-access command overhead. |
| Clock Speed | 108MHz Single Data Rate; achieves ≤25ns read latency and sub-100ns write latency in SDR mode. |
| Supply Voltage | 1.71V–2.00V; compatible with 1.8V logic systems and eliminates level-shifting in low-power industrial designs. |
| Operating Temp | −40°C to +85°C (Industrial grade); validated for continuous operation in PLC backplanes and medical diagnostics enclosures. |
| Endurance | Virtually unlimited (>1015 cycles); eliminates wear leveling firmware and enables direct register-mapped I/O logging. |
| Data Retention | 20+ years at 85°C; ensures data integrity across product lifecycle without backup batteries or capacitors. |
Pinout & Package
Package: 8-pad DFN (WSON), 5.0mm × 6.0mm, exposed thermal pad, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable; falling edge initiates instruction latch; high state places device in standby (ISB current). |
| WP# / IO[2] | Bidirectional Write Protect / Quad I/O | In SPI mode: hardware write lock for status register when pulled low; in QPI mode: bidirectional data lane for address/data transfer. |
| SI / IO[0] | Input / Bidirectional Serial Data | In SPI: command/address/data input on rising clock edge; in QPI: command lane only (1-4-4 nomenclature). |
| CLK | Clock Input | Drives synchronous timing; SDR uses rising edge for input, falling edge for output; DDR uses both edges. |
| IO[3] | Bidirectional Quad I/O | Carries address/data in QPI mode; tied to VCC if unused in SPI mode to prevent floating. |
| SO / IO[1] | Output / Bidirectional Serial Data | In SPI: data output on falling clock edge; in QPI: full bidirectional data lane for address/data. |
| VCC | Power Supply | 1.71–2.00V core/I/O rail; requires local 100nF decoupling capacitor per datasheet layout guidelines. |
| VSS | Ground | Common reference for core and I/O; must be connected to low-impedance PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| eXecute-In-Place (XIP) | Enables sequential instruction execution without repeated command loading; reduces random access time by >40% vs standard SPI reads. |
| Hardware Write Protection | WP# pin directly gates status register writes when enabled; prevents accidental configuration corruption during power transients. |
| Augmented Storage Array | 256-byte user-programmable space with per-section (32B) write protection; ideal for storing calibration constants or firmware version stamps. |
| JEDEC Reset Support | Standardized reset command (66h/99h) restores device to known state without power cycle; critical for fail-safe recovery in safety-critical systems. |
| Dual Low-Power Modes | Deep Power Down (IDPD) draws <1µA; Hibernate retains configuration while reducing current to ~5µA; both preserve memory contents. |

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 CY14V108L | 8Mb nvSRAM with 3.3V supply (2.7–3.6V); no QPI mode; uses legacy SPI (1-1-1) only. | Limited to single-lane SPI; lacks XIP and augmented storage; requires external capacitor for data retention. | Select when 3.3V system integration and legacy SPI compatibility outweigh bandwidth and feature needs. |
| Everspin MR25H10DF | 8Mb parallel-interface STT-MRAM; 32-pin TSOP; 3.3V supply; no serial interface. | Requires full parallel bus (address/data/control); incompatible with SPI-based microcontrollers; higher PCB footprint. | Select only for existing parallel-memory designs where board redesign is feasible and QSPI constraint does not apply. |
Compared with CY14V108L and MR25H10DF, the M10082040108X0IWAY uniquely combines 108MHz QPI bandwidth, 1.8V operation, and integrated augmented storage-enabling compact, low-power, high-reliability embedded storage without external components or interface translation.

FAQ
What is the operating voltage range for M10082040108X0IWAY?
The M10082040108X0IWAY operates from 1.71V to 2.00V. This 1.8V nominal range is optimized for low-power industrial microcontrollers and eliminates level-shifting circuitry. Operation outside this window is not guaranteed, and the device enters undefined state below 1.71V or above 2.00V per datasheet Table 7.
Does M10082040108X0IWAY support Quad SPI (QPI) mode?
Yes, M10082040108X0IWAY fully supports Quad SPI (4-4-4) mode as defined in JEDEC JESD216. In QPI mode, IO[0:3] carry command, address, and data simultaneously, enabling 432MB/s effective throughput at 108MHz clock. The device also supports legacy SPI (1-1-1) and DPI modes for backward compatibility.
How is write protection implemented on M10082040108X0IWAY?
M10082040108X0IWAY implements dual-layer write protection: hardware-based via the WP# pin (active-low, controls status register writes when enabled) and software-based via status register bits (BPSEL[2:0], TBSEL, SNPEN). Both mechanisms can be used independently or concurrently to protect main memory, augmented storage, and configuration registers.
What is the purpose of the Augmented Storage Array in M10082040108X0IWAY?
The 256-byte Augmented Storage Array in M10082040108X0IWAY is a dedicated, user-programmable region segmented into eight 32-byte sections. Each section can be individually write-protected. It is intended for storing infrequently updated but mission-critical data such as calibration coefficients, serial numbers, or firmware version stamps-separate from the main memory array.
Is M10082040108X0IWAY compatible with JEDEC-standard reset commands?
Yes, M10082040108X0IWAY supports JEDEC-standard reset instructions: Enable Reset (66h) followed by Reset (99h). This sequence returns the device to its default operational state-including clearing volatile status flags and reinitializing internal logic-without requiring a power cycle, which is essential for robust recovery in safety-critical systems.
