Product details
Overview
M30162040108X0PWAR from Renesas is a 16Mbit serial STT-MRAM non-volatile memory IC with QSPI interface, 108MHz SDR clock speed, 1.71–2.0V supply voltage, and industrial-plus temperature range (−40°C to +105°C). It delivers SRAM-compatible read/write timing, zero write latency, and persistent data retention without backup power-used in real-time industrial control logging and firmware storage.
For engineers reviewing the M30162040108X0PWAR datasheet, M30162040108X0PWAR pinout, M30162040108X0PWAR application, or M30162040108X0PWAR equivalent, key selection criteria include QSPI x4 interface compatibility, 108MHz SDR timing compliance, hardware/software write protection support, 256-byte augmented storage array usage, and DFN-8 (WSON) package integration into space-constrained embedded systems.
Technical Context
The M30162040108X0PWAR 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 dual power domains for VCC (1.8V core/I/O) and VSS.
It features eXecute-In-Place (XIP) mode to eliminate per-access command overhead, Deep Power Down (3µs entry, 400µs exit) and Hibernate (3µs entry, 450µs exit) low-power states with full configuration retention, and hardware-based WP# pin plus software-configurable block protection via Status Register BPSEL bits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 16 Mbit (2 MByte) main memory array - supports firmware image storage and runtime parameter logging without wear-out concerns. |
| Interface | Quad SPI (QPI, 4-4-4) - enables 4-bit parallel data transfer on address and data phases, doubling bandwidth vs. standard SPI. |
| Max Clock Speed | 108 MHz in Single Data Rate mode - achieves up to 54 MB/s effective read throughput with no wait states. |
| Supply Voltage | 1.71 V – 2.00 V - compatible with modern 1.8V logic families and low-power microcontrollers. |
| Operating Temp | −40°C to +105°C (Industrial Plus) - qualified for under-hood automotive ECUs and factory-floor PLCs. |
| Endurance | Virtually unlimited (>10¹⁵ cycles) - eliminates refresh management and wear-leveling firmware overhead. |
| Data Retention | 20+ years at +105°C - ensures long-term reliability in unpowered storage applications like black-box event logs. |
Pinout & Package
Package: 8-pad DFN (WSON), 5.0 mm × 6.0 mm, wettable flank, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable signal; must fall before first instruction; controls standby/active power state transition. |
| WP# / IO[2] | Bidirectional I/O or Hardware Write Protect | In SPI mode: input-only write protect; when asserted low with WP#EN=1, locks status register; 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] for 4-line transfers. |
| 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; required for 4-line address/data transfer; must be pulled high 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 | 1.71–2.00 V core and I/O supply; requires local 100 nF decoupling capacitor per datasheet layout guidance. |
| VSS | Ground | Common return path for core and I/O circuits; must be low-impedance connection to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| eXecute-In-Place (XIP) | Enables continuous burst reads without repeated command issuance - reduces average access latency by >30% in firmware execution scenarios. |
| Augmented Storage Array | 256-byte user-programmable section with per-32-byte write protection - ideal for storing calibration coefficients or secure keys independent of main array. |
| Hardware + Software Protection | WP# pin + Status Register BPSEL[2:0] and TBSEL bits - allows hierarchical locking of top/bottom memory blocks and serial number registers. |
| JEDEC Reset Support | Standard reset command (66h) restores default register values - simplifies system recovery after brownout or watchdog timeout events. |
| Deep Power Down Mode | Reduces ICC to <1 µA while retaining all memory contents and register settings - extends battery life in always-on monitoring 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 FM25V16-G | 16Mb F-RAM; 3.3V only (2.7–3.6V); max 40MHz SPI; no QPI or XIP support | Limited to lower-speed control interfaces; lacks augmented storage and JEDEC reset | Choose for legacy 3.3V systems where ultra-low write energy is critical and bandwidth <20MB/s suffices. |
| Infineon Technologies CY14B116N-ZSP25XI | 16Mb nvSRAM; 3.3V only; built-in lithium battery backup; 25ns async access; no serial interface | Requires board-level backup power design; incompatible with SPI host controllers | Choose only when deterministic nanosecond-level random access is mandatory and board space permits coin-cell integration. |
Compared with FM25V16-G and CY14B116N-ZSP25XI, the M30162040108X0PWAR uniquely combines 108MHz QSPI bandwidth, 1.8V operation, XIP, and augmented storage in a single 5×6mm DFN package-making it optimal for next-generation industrial edge nodes requiring high-speed, maintenance-free non-volatility.

FAQ
What is the exact memory density and organization of the M30162040108X0PWAR?
The M30162040108X0PWAR provides 16 Mbit (2,097,152 bits) of main memory organized as 2,097,152 × 1, accessible via 24-bit addressing (000000h–1FFFFFh). It also includes a separate 256-byte Augmented Storage Array mapped at 000000h–0000FFh, divided into eight 32-byte programmable and individually protectable sections.
Does the M30162040108X0PWAR support both Single Data Rate and Double Data Rate SPI modes?
The M30162040108X0PWAR supports Single Data Rate (SDR) mode at up to 108 MHz, but does not support Double Data Rate (DDR) operation at 54 MHz. Its ordering code "0108" explicitly denotes the 108 MHz SDR variant; DDR-capable versions use "0054" in the part number and are distinct SKUs.
What package type and footprint does the M30162040108X0PWAR use?
The M30162040108X0PWAR uses an 8-pad DFN (WSON) package measuring 5.0 mm × 6.0 mm with wettable flanks. Pinout matches industry-standard 8-pin SOIC but in a smaller, thermally enhanced leadless format-compatible with reflow soldering and automated optical inspection.
How does the write protection mechanism work on the M30162040108X0PWAR?
The M30162040108X0PWAR implements dual-layer write protection: hardware-based via the WP# pin (active-low, requires WP#EN bit = 1 in Status Register), and software-based via Status Register BPSEL[2:0] and TBSEL bits to lock top/bottom memory blocks. The Augmented Storage Array supports per-section write protection independent of main array settings.
Is the M30162040108X0PWAR compatible with standard Quad SPI controllers?
Yes-the M30162040108X0PWAR fully complies with JEDEC JESD251 QPI standards and supports standard Quad SPI instructions including Read Quad IO (6Bh), Write Quad IO (32h), and Quad Page Program (38h). It operates in QPI mode (4-4-4) with all four I/O lines active for command, address, and data phases.
