Product details
Overview
M30162040054X0IWAR from Renesas is a 16Mbit serial STT-MRAM non-volatile memory IC with QSPI interface, 54MHz DDR timing, 1.71–2.0V or 2.7–3.6V supply, and industrial temperature range (−40°C to +85°C) in 8-pad DFN (WSON) package. It delivers SRAM-compatible read/write latency, infinite endurance, and data retention without backup power - ideal for factory automation controllers requiring deterministic write persistence.
For engineers reviewing the M30162040054X0IWAR datasheet, M30162040054X0IWAR pinout, M30162040054X0IWAR application, or M30162040054X0IWAR equivalent, key selection criteria include QSPI DDR timing compliance, dual-voltage operation, hardware/software write protection, 256-byte augmented storage array, and industrial-grade thermal reliability.
Technical Context
The M30162040054X0IWAR implements a 40nm pMTJ spin-transfer torque MRAM array with quad SPI (QPI: 4-4-4) interface supporting both SDR and DDR modes. Its architecture includes dedicated command/address/data buffers, status/configuration registers, and independent 256-byte augmented storage array with per-section write protection.
It supports eXecute-In-Place (XIP), Deep Power Down (EDP/B9h), and Hibernate (EHBN/BAh) modes while maintaining full configuration state and data integrity. The device uses JEDEC-standard reset and provides 64-bit unique ID plus user-programmable 64-bit serial number for traceability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 16 Mbit (2 MByte) main memory array - supports large firmware parameter tables and real-time logging without wear leveling. |
| Interface | Quad SPI (QPI, 4-4-4) with DDR mode at 54MHz - enables 432 MB/s effective throughput for burst reads/writes. |
| Voltage Range | 1.71–2.00V or 2.70–3.60V - compatible with both 1.8V and 3.3V system rails without level shifters. |
| Operating Temp | −40°C to +85°C (Industrial) - qualified for uncontrolled ambient environments in PLCs and motor drives. |
| Endurance & Retention | Virtually unlimited write cycles (>10¹⁵) and >20-year data retention at 85°C - eliminates refresh overhead and lifetime estimation uncertainty. |
| Package | 8-pad DFN (WSON), 5.0 × 6.0 mm - surface-mount footprint compatible with high-density industrial PCB layouts. |
| Protection | Hardware WP# pin + software-configurable block protect (BP[2:0]) and top/bottom select - enables granular, field-updatable security policies. |
Pinout & Package
8-pad DFN (WSON) package, 5.0 mm × 6.0 mm, 0.5 mm pitch, exposed thermal pad (EP). RoHS-compliant, moisture sensitivity level (MSL) 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable; falling edge initiates instruction sequence; high puts device in standby with tri-stated I/Os. |
| WP# / IO[2] | Write Protect Input / Bidirectional Data 2 | In Single SPI: hardware write lock for status register when WP# = Low and WP#EN = 1; in QPI: bidirectional data lane. |
| SI / IO[0] | Serial Input / Bidirectional Data 0 | In Single SPI: command/address/data input on rising CLK edge; in QPI: primary bidirectional data lane. |
| CLK | Clock Input | Synchronous timing reference; DDR mode uses both rising/falling edges for address/data transfer. |
| IO[3] | Bidirectional Data 3 | QPI-only data lane; must be tied to VCC if unused in lower-pin-count modes. |
| SO / IO[1] | Serial Output / Bidirectional Data 1 | In Single SPI: data output on falling CLK edge; in QPI: secondary bidirectional data lane. |
| VCC | Power Supply | Core and I/O supply; supports 1.8V or 3.3V operation; requires local 100nF + 1µF decoupling. |
| VSS | Ground | Common return path for core and I/O; must be low-impedance connection to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| eXecute-In-Place (XIP) | Enables continuous read sequences without repeated command overhead - reduces random access latency by up to 40% vs standard SPI. |
| Augmented Storage Array | 256-byte user-programmable section, divided into eight 32-byte protected blocks - ideal for storing calibration data, MAC addresses, or firmware version stamps. |
| JEDEC Reset Support | Standardized reset command (66h) ensures interoperability with existing SPI host firmware stacks without custom initialization logic. |
| Dual-Voltage Operation | Single device supports both 1.8V and 3.3V systems - simplifies BOM management across product variants and voltage domains. |
| Deep Power Down Mode | Enters sub-1µA quiescent current state in ≤3 µs and exits in ≤400 µs - enables rapid wake-up in 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 FM25V10-G | 1 Mbit F-RAM; 40 MHz SPI; 2.0–3.6V only; no DDR mode; no augmented storage array. | Limited density and voltage flexibility; lacks QPI and XIP - suitable only for small config stores. | Select when ultra-low write energy (<3.5 µJ) is prioritized over density and speed. |
| Infineon Technologies CY14V108N-ZSP25XI | 8 Mbit nvSRAM; 25 MHz parallel interface; 3.0–3.6V only; requires external capacitor for write-back. | Parallel bus increases pin count and layout complexity; capacitor dependency adds BOM cost and failure mode. | Select only for legacy parallel-interface designs where migration to serial is not feasible. |
Compared with FM25V10-G and CY14V108N-ZSP25XI, the M30162040054X0IWAR offers 2× higher density than the F-RAM, 100% higher interface bandwidth than the nvSRAM, dual-voltage support, and integrated augmented storage - making it optimal for new industrial designs demanding scalability, low latency, and long-term data integrity.

FAQ
What is the maximum clock frequency supported by M30162040054X0IWAR in DDR mode?
The M30162040054X0IWAR supports Double Data Rate (DDR) mode at 54 MHz, delivering an effective interface bandwidth of 432 MB/s in Quad SPI (4-4-4) configuration. This is confirmed in the "Features" section of the datasheet and validated in Table 3 (Interface Modes) and Table 4 (Clock Edge Usage). The part number suffix "0054" explicitly denotes the 54 MHz DDR capability.
Does M30162040054X0IWAR require an external backup power source or capacitor?
No, the M30162040054X0IWAR does not require any external backup power source, capacitor, or battery. As a true non-volatile MRAM, it retains data indefinitely at power-off using intrinsic magnetic storage. This eliminates the reliability risks, size penalties, and lifetime limitations associated with capacitor-based nvSRAM or battery-backed SRAM solutions.
Can M30162040054X0IWAR operate at both 1.8V and 3.3V supply voltages?
Yes, the M30162040054X0IWAR supports two independent VCC ranges: 1.71–2.00 V and 2.70–3.60 V. This dual-voltage capability is specified in the "Features" section and Table 7 (1.8V timing) and Table 6 (3.0V timing). The device automatically adapts to the applied rail - no configuration or external circuitry is needed.
How is write protection implemented on M30162040054X0IWAR?
M30162040054X0IWAR implements dual-layer write protection: hardware-based via the WP# pin (active-low, configurable via Status Register bit SR[7]), and software-based via block protect bits (BP[2:0]) and top/bottom select (TBSEL) in the Status Register. Both mechanisms can be used independently or concurrently to safeguard memory regions including the 256-byte augmented storage array.
Is the 256-byte Augmented Storage Array on M30162040054X0IWAR separately addressable and protected?
Yes, the 256-byte Augmented Storage Array on M30162040054X0IWAR resides at fixed address range 000000h–0000FFh and is partitioned into eight 32-byte sections (0–7). Each section can be individually programmed and write-protected using the Augmented Storage Array Protection Register (ASAPR), enabling secure storage of calibration data, serial numbers, or cryptographic keys without affecting main memory.
