Product details
Overview
M30082040108X0PWAY from Renesas is a 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 serves as persistent SRAM (P-SRAM) in real-time data logging systems requiring zero write latency and infinite endurance.
For engineers reviewing the M30082040108X0PWAY datasheet, M30082040108X0PWAY pinout, M30082040108X0PWAY application, or M30082040108X0PWAY equivalent, key selection criteria include its QSPI x4 interface timing, hardware/software write protection, 256-byte augmented storage array, and dual-voltage operation across extended temperature.
Technical Context
This MRAM uses 40nm pMTJ STT technology enabling true random access with SRAM-compatible read/write timings and non-volatility. It supports Quad SPI (4-4-4), Single Data Rate mode at 108MHz, and executes-in-place (XIP) to reduce command overhead during burst reads.
The device integrates hardware write protection via WP# pin and software-based protection through configurable status and block protect bits. Its architecture includes a dedicated 256-byte augmented storage array-separate from main memory-with per-section write protection and user-programmable serial number/unique ID registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 8Mbit (1,048,576 × 8-bit organization) |
| Interface | Quad SPI (4-4-4) supporting SDR up to 108MHz - enables high-throughput sequential and random access without erase cycles |
| Supply Voltage | 1.71–2.00V or 2.70–3.60V - dual-voltage support simplifies integration into 1.8V or 3.3V system rails |
| Operating Temp | −40°C to +105°C (Industrial Plus) - qualified for harsh environments including factory automation and medical diagnostics |
| Endurance & Retention | Virtually unlimited write cycles (>10¹⁵) and ≥20-year data retention - eliminates wear leveling and refresh logic |
| Augmented Storage | 256-byte user-programmable array with section-level write protection - ideal for storing calibration data or firmware metadata |
| Protection | Hardware WP# pin + software-configurable top/bottom/block protection - prevents accidental writes during power transitions or firmware updates |
Pinout & Package
Package: 8-pad DFN (WSON), 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 sequence; high state places device in standby with tri-stated outputs |
| WP# / IO[2] | Bidirectional I/O or Hardware Write Protect | In SPI mode: hardware write protect for status register when enabled; in QPI mode: bidirectional data line IO[2] |
| SI / IO[0] | Serial Input or Bidirectional Data 0 | In SPI: unidirectional command/address/data input; in QPI: bidirectional data line IO[0] |
| CLK | Clock Input | Synchronous timing reference; rising edge latches commands in SDR/DDR; both edges used for address/data in DDR mode |
| IO[3] | Bidirectional Data 3 | QPI-only data line; must be tied to VCC if unused in SPI mode |
| SO / IO[1] | Serial Output or Bidirectional Data 1 | In SPI: unidirectional data output on falling clock edge; in QPI: bidirectional data line IO[1] |
| VCC | Power Supply | Core and I/O supply - accepts either 1.8V or 3.3V rail with internal regulation |
| VSS | Ground | Common reference for core and I/O circuits - requires local decoupling per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Execute-In-Place (XIP) | Enables continuous read/write sequences without repeated command issuance - reduces latency by ~30% in burst-access firmware execution |

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 FM25V05 | 512Kb F-RAM; 40MHz SPI; 2.7–3.6V only; no QPI or XIP support | Limited density and interface speed; lacks augmented storage and JEDEC reset | Select when lower cost and moderate throughput suffice, but not for 8Mb+ or 108MHz requirements |
| Infineon Technologies CY14B108N | 8Mb nvSRAM with parallel interface; 15ns access; requires external backup capacitor | Parallel bus increases PCB routing complexity; capacitor dependency adds BOM cost and reliability risk | Choose only if legacy parallel interface is mandated; otherwise M30082040108X0PWAY offers simpler design and superior endurance |
Compared with FM25V05 and CY14B108N, M30082040108X0PWAY delivers higher density, faster QSPI interface, no external components, and guaranteed 20-year retention - making it optimal for new designs prioritizing reliability, miniaturization, and long-term supply stability.

FAQ
What voltage ranges does the M30082040108X0PWAY support?
M30082040108X0PWAY supports two independent supply ranges: 1.71V to 2.00V (1.8V nominal) and 2.70V to 3.60V (3.3V nominal). The device automatically adapts to the applied VCC level and does not require external voltage translation. Both ranges are fully specified across the −40°C to +105°C operating temperature, and M30082040108X0PWAY maintains full functionality-including QSPI x4 operation and write protection-within either range.
Does the M30082040108X0PWAY require an external backup capacitor or battery?
No, M30082040108X0PWAY does not require any external backup components. As a true non-volatile MRAM, it retains data indefinitely without power due to its magnetic storage mechanism. Unlike nvSRAM or battery-backed SRAM, M30082040108X0PWAY eliminates capacitor aging, leakage, and field-replacement concerns while guaranteeing data integrity across unlimited power cycles and thermal extremes.
How is write protection implemented on the M30082040108X0PWAY?
M30082040108X0PWAY implements dual-layer write protection: hardware-based via the WP# pin (active-low, disables status register writes when enabled), and software-based via configurable bits in the Status Register (TBSEL, BPSEL[2:0]) that define protected memory blocks or top/bottom regions. Both mechanisms can be used simultaneously, and M30082040108X0PWAY enforces protection even during power transitions-ensuring robust firmware and calibration data integrity.
What is the purpose of the Augmented Storage Array in the M30082040108X0PWAY?
The Augmented Storage Array is a dedicated 256-byte memory region separate from the main 8Mb array, divided into eight 32-byte sections. Each section can be individually programmed and write-protected. M30082040108X0PWAY uses this area for storing critical, infrequently updated data such as calibration coefficients, device serial numbers, or security keys-providing isolation from main memory operations and preventing accidental corruption during firmware updates.
Is the M30082040108X0PWAY pin-compatible with other members of the Mxxxx204 family?
Yes, all Mxxxx204 devices-including M30082040108X0PWAY-share identical 8-pad DFN (WSON) and 8-pin SOIC footprints, pin assignments, and electrical signaling. Density (4Mb/8Mb/16Mb), voltage (1.8V/3.3V), speed (108MHz/54MHz), and temperature grade (Industrial/Industrial Plus) are encoded in the part number but do not affect physical or logical interface compatibility. M30082040108X0PWAY can be substituted within the same package without PCB changes, provided system firmware accounts for address space size.
