Product details
Overview
M30082040054X0IWAY from Renesas is a 8Mb serial STT-MRAM (Spin-Transfer Torque Magnetoresistive RAM) with QSPI interface, 54MHz DDR timing, 1.71–2.0V or 2.7–3.6V supply, industrial temperature range (−40°C to +85°C), and 8-pad DFN (WSON) package. It serves as persistent SRAM (P-SRAM) in real-time data logging systems requiring zero-write-latency non-volatility.
For engineers reviewing the M30082040054X0IWAY datasheet, M30082040054X0IWAY pinout, M30082040054X0IWAY application, or M30082040054X0IWAY equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial use cases, and two technically documented alternative parts for memory subsystem design.
Technical Context
This MRAM implements a 40nm pMTJ STT-MRAM cell array with true random access, SRAM-compatible read/write timing, and no write endurance limit. Its QSPI interface supports 1-4-4 command-address-data configuration and both SDR (108MHz) and DDR (54MHz) modes - the M30082040054X0IWAY is specifically configured for DDR operation at 54MHz.
The device integrates hardware write protection via WP# pin and software-based block protection through configurable status and configuration registers. It includes a dedicated 256-byte augmented storage array with per-section write protection and supports JEDEC-standard reset, deep power-down, and hibernate modes while retaining full data and configuration state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 8 Megabit (1,048,576 × 8-bit organization); enables compact firmware/data storage without external refresh circuitry. |
| Interface | Quad SPI (QPI, 4-4-4 mode); supports high-throughput burst reads/writes with single-cycle command overhead. |
| Clock Speed | 54MHz Double Data Rate; delivers effective 108MB/s peak bandwidth with minimal CPU wait states. |
| Supply Voltage | 1.71V–2.00V or 2.70V–3.60V; dual-voltage support simplifies integration into 1.8V or 3.3V system rails. |
| Operating Temp | −40°C to +85°C (Industrial); qualified for factory automation, medical diagnostics, and embedded control environments. |
| Endurance & Retention | Virtually unlimited write cycles (>10¹⁵) and >20-year data retention at 85°C; eliminates wear leveling and backup battery requirements. |
| Package | 8-pad DFN (WSON), 5.0mm × 6.0mm; surface-mount compatible with standard reflow profiles and space-constrained PCB layouts. |
Pinout & Package
8-pad DFN (WSON) package, 5.0mm × 6.0mm body, wettable flank leads, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable signal; falling edge initiates instruction execution; high state places device in standby with tri-stated outputs. |
| WP# / IO[2] | Bidirectional I/O / Hardware Write Protect | In SPI mode: hardware write protect for status register when WP# = low and WP#EN = 1; in QPI mode: bidirectional data line IO[2]. |
| SI / IO[0] | Input / Bidirectional Data 0 | In SPI: serial input only; in QPI: bidirectional data line IO[0]; used for command/address/data in all supported modes. |
| CLK | Clock Input | Synchronous timing reference; DDR mode uses both rising and falling edges for address/data transfer. |
| IO[3] | Bidirectional Data 3 | QPI-only data line; enables 4-lane parallel data transfer for high-speed burst operations. |
| SO / IO[1] | Output / Bidirectional Data 1 | In SPI: serial output only; in QPI: bidirectional data line IO[1]; data output always begins on clock falling edge. |
| VCC | Power Supply | Single supply for core and I/O; supports 1.8V or 3.3V operation with internal regulation. |
| VSS | Ground | Common reference for core and I/O circuits; requires local decoupling per datasheet layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| eXecute-In-Place (XIP) | Enables continuous read/write sequences without repeated command issuance, reducing latency by up to 40% in firmware execution scenarios. |
| Augmented Storage Array | 256-byte user-programmable section with per-32-byte write protection; ideal for storing calibration data, MAC addresses, or secure keys. |
| Hardware + Software Protection | WP# pin + configurable BPSEL bits allow hierarchical protection of memory blocks and registers - prevents accidental overwrites during field updates. |
| Deep Power Down & Hibernate | Reduces current to <1µA while preserving full memory content and register state; exit time ≤400µs enables rapid wake-up in energy-sensitive applications. |
| Unique & Programmable IDs | 64-bit factory-unique ID + 64-bit user-programmable serial number; supports device traceability and secure provisioning in OEM production. |

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; 2.7–3.6V only; no DDR mode; lower write endurance (10¹⁴ cycles) than MRAM. | Limited to 3.3V systems; lacks QPI and XIP; suitable where cost sensitivity outweighs bandwidth needs. | Select if legacy SPI-only interface and lower cost are prioritized over speed and voltage flexibility. |
| Infineon Technologies CY14B108N-ZSP25XI | 8Mb nvSRAM; 25MHz parallel interface; requires external capacitor for store operation; 10¹² endurance. | Parallel bus footprint; capacitor-dependent non-volatility; not pin-compatible; higher board area and component count. | Choose only when existing parallel-memory architecture precludes serial interface redesign. |
Compared with FM25V08-G and CY14B108N-ZSP25XI, the M30082040054X0IWAY delivers superior bandwidth via QPI DDR, broader voltage support, and orders-of-magnitude higher endurance - making it optimal for high-write-frequency, low-latency, and mixed-voltage industrial designs.

FAQ
What is the operating voltage range for the M30082040054X0IWAY?
The M30082040054X0IWAY supports two independent supply ranges: 1.71V to 2.00V (1.8V nominal) and 2.70V to 3.60V (3.3V nominal). Both ranges are fully specified across the −40°C to +85°C industrial temperature grade. The device automatically adapts internal regulation and timing parameters to the applied VCC level, enabling drop-in compatibility in either rail without external level shifting.
Does the M30082040054X0IWAY support Quad SPI (QPI) mode?
Yes, the M30082040054X0IWAY supports full Quad SPI (QPI) operation in 4-4-4 mode using all four I/O pins (IO[0]–IO[3]). This enables high-speed burst reads and writes with minimal instruction overhead. The device also supports Dual SPI and standard SPI modes, and its QPI implementation complies with JEDEC JESD251 standards for interoperability with common host controllers.
What is the endurance rating of the M30082040054X0IWAY?
The M30082040054X0IWAY has virtually unlimited write endurance - rated at greater than 10¹⁵ write cycles - due to its STT-MRAM technology. Unlike Flash or EEPROM, it exhibits no wear-out mechanism. This eliminates the need for wear-leveling algorithms and guarantees consistent performance over the full product lifetime, even under continuous logging workloads.
How does the Augmented Storage Array function in the M30082040054X0IWAY?
The M30082040054X0IWAY includes a dedicated 256-byte Augmented Storage Array, organized into eight 32-byte sections. Each section can be independently programmed and write-protected via configuration registers. This area is ideal for storing immutable identifiers, calibration constants, or security keys - separate from main memory and protected against accidental overwrite during firmware updates.
Is the M30082040054X0IWAY pin-compatible with other members of the Mxxxx204 family?
Yes, the M30082040054X0IWAY shares identical pinout, package dimensions, and electrical interface behavior with all Mxxxx204 variants in the same package type (e.g., WA = 8-pad DFN). Pin compatibility extends across densities (4Mb/8Mb/16Mb), voltage grades (1.8V/3.3V), and speed grades (54MHz/108MHz), enabling flexible BOM management and design reuse without PCB changes.
