Product details
Overview
M10162040054X0IWAR from Renesas is a 16Mb serial STT-MRAM non-volatile memory IC with QSPI interface, 54MHz DDR timing, 1.71–2.0V supply, industrial temperature range (−40°C to +85°C), and 8-pad DFN (WSON) package. It delivers SRAM-compatible read/write performance with persistent data retention-ideal for real-time industrial control logging where power loss must not corrupt state.
For engineers reviewing the M10162040054X0IWAR datasheet, M10162040054X0IWAR pinout, M10162040054X0IWAR application, or M10162040054X0IWAR equivalent, this page provides verified technical context, pin-level design meaning, JEDEC-compliant reset support, hardware/software write protection, and XIP-enabled low-latency execution-in-place capability for deterministic embedded firmware storage.
Technical Context
The M10162040054X0IWAR implements a 40nm pMTJ spin-transfer torque MRAM array with quad SPI (QPI: 4-4-4) interface supporting Double Data Rate mode at 54MHz. Its architecture includes dedicated command/address/data buffers, on-die voltage regulation, and dual low-power states (Deep Power Down and Hibernate) that preserve configuration and data without external backup.
It features a 256-byte Augmented Storage Array-separate from main memory-with per-section (32-byte) programmability and individual write protection. Register mapping includes Status, Configuration (1–4), Device ID, Unique ID, and Serial Number registers-all accessible via standard SPI instructions with JEDEC Reset compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 16Mbit (2,097,152 bytes); supports full random-access reads/writes with no erase cycles |
| Interface | Quad SPI (QPI 4-4-4); enables 216MB/s effective throughput in DDR mode at 54MHz |
| Supply Voltage | 1.71V–2.00V; compatible with 1.8V system rails and eliminates level-shifting in modern low-voltage controllers |
| Operating Temp | −40°C to +85°C (Industrial); validated for continuous operation in factory automation enclosures |
| Endurance & Retention | Virtually unlimited write cycles (>10¹⁵) and >20-year data retention at 85°C-no wear leveling required |
| Package | 8-pad DFN (WSON), 5.0mm × 6.0mm; RoHS-compliant, surface-mountable, and footprint-compatible with SOIC-8 alternatives |
| Power Modes | Deep Power Down (IDPD ≤ 2µA) and Hibernate (IHBN ≤ 15µA); both retain full memory content and register state |
Pinout & Package
8-pad DFN (WSON), 5.0mm × 6.0mm, moisture-sensitive level 3, exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable; falling edge initiates instruction latch; high-Z output when deasserted |
| WP# / IO[2] | Bidirectional I/O or Hardware Write Protect | In SPI mode: hardware lock for Status Register when WP# = Low and WP#EN = 1; in QPI: bidirectional data line IO[2] |
| SI / IO[0] | Input or Bidirectional Data 0 | In SPI: serial input only; in QPI: bidirectional data line IO[0] for command/address/data |
| CLK | Clock Input | Synchronous timing reference; DDR mode uses both rising/falling edges for address/data transfer |
| IO[3] | Bidirectional Data 3 | QPI-only; carries command/address/data in 4-4-4 mode; may be tied to VCC if unused |
| SO / IO[1] | Output or Bidirectional Data 1 | In SPI: serial output only (data valid on falling edge); in QPI: bidirectional data line IO[1] |
| VCC | Core & I/O Supply | 1.71–2.00V primary power; requires local 100nF decoupling per datasheet layout guidelines |
| VSS | Ground Reference | Common return for core and I/O; must be low-impedance connection to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| eXecute-In-Place (XIP) | Enables sequential instruction execution without repeated command overhead-reduces random read latency by up to 40% vs standard SPI |
| Hardware + Software Protection | WP# pin locks Status Register; configurable block protect (BPSEL[2:0]) and top/bottom selection (TBSEL) prevent unintended writes to memory sections |
| Augmented Storage Array | 256-byte user-programmable area split into eight 32-byte sections, each independently write-protectable for secure calibration or firmware metadata |
| JEDEC Reset Support | Standardized reset command (66h) restores device to known operational state-critical for field-upgrade reliability |
| Unique & Programmable IDs | 64-bit factory-assigned UID + 64-bit user-writable serial number-enables traceability and secure device binding in OEM systems |

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 | 1Mb density, 3.0V supply (2.7–3.6V), SOIC-8 only, no XIP or Augmented Storage Array | Limited to smaller code/data footprints; lacks per-section write protection and JEDEC Reset | Select when 1Mb capacity suffices and 3.0V rail simplifies BOM; avoid for 16Mb or 1.8V designs |
| Infineon Technologies CY14B108N-ZSP25XI | 8Mb density, 2.7–3.6V, SOIC-8, supports SPI/SDR only (no QPI or DDR), no Augmented Storage Array | Lower bandwidth (max 40MHz SDR), no hardware write protect pin, no unique ID | Choose for cost-sensitive 8Mb applications requiring basic MRAM persistence-but not for high-speed or secure identity use cases |
Compared with FM25V10-G and CY14B108N-ZSP25XI, the M10162040054X0IWAR offers 2× higher density, 1.8V operation, QPI/DDR interface, XIP, and secure augmented storage-making it optimal for next-generation industrial and medical edge devices demanding scalability, speed, and data integrity.

FAQ
What is the maximum clock frequency supported by M10162040054X0IWAR in Double Data Rate mode?
The M10162040054X0IWAR supports 54MHz in Double Data Rate (DDR) mode, achieving an effective interface bandwidth of 216MB/s using quad I/O lines (4-4-4). This is confirmed in the "Features" section of the datasheet and validated across industrial temperature range (−40°C to +85°C) with 1.71–2.00V supply. The M10162040054X0IWAR does not support 108MHz DDR-only SDR at that rate.
Does M10162040054X0IWAR require external hardware for write protection, or is software-based protection sufficient?
The M10162040054X0IWAR supports both hardware and software write protection. Hardware protection uses the WP# pin in conjunction with the WP#EN bit in the Status Register; software protection uses TBSEL and BPSEL[2:0] bits to define protected memory blocks. For robust security, Renesas recommends enabling both-hardware lock prevents accidental writes during debug, while software settings enforce logical partitioning. The M10162040054X0IWAR's dual-layer scheme eliminates need for external lock circuits.
Can M10162040054X0IWAR retain data during deep power-down mode, and how long does exit take?
Yes, the M10162040054X0IWAR retains full memory and register contents-including configuration and Augmented Storage Array-in Deep Power Down mode. Exit time is specified as ≤400µs (tEXDPD) after CS# goes low, with no initialization sequence required. This behavior is guaranteed across −40°C to +85°C and enables rapid wake-up in energy-constrained applications like portable medical devices. The M10162040054X0IWAR maintains all settings post-exit without host reconfiguration.
Is the 256-byte Augmented Storage Array in M10162040054X0IWAR physically separate from main memory, and can it be write-protected per section?
Yes, the 256-byte Augmented Storage Array is architecturally isolated from the 16Mb main MRAM array and mapped to fixed addresses 000000h–0000FFh. It is divided into eight 32-byte sections (0–7), each individually programmable and write-protectable via dedicated bits in the Augmented Storage Array Protection Register. This allows secure storage of calibration data, firmware signatures, or device-specific keys without risking main memory corruption. The M10162040054X0IWAR supports per-section locking independent of main array protection schemes.
What JEDEC-standard commands does M10162040054X0IWAR support, and why is JEDEC Reset important?
The M10162040054X0IWAR supports JEDEC-standard Reset (66h) and Release from Deep Power Down (ABh) commands. JEDEC Reset returns the device to a known operational state-including clearing status flags and re-enabling instruction decoding-without requiring power cycle. This is essential for field-upgrade resilience and watchdog recovery in unattended systems. Unlike proprietary resets, JEDEC Reset ensures interoperability across toolchains and avoids vendor lock-in. The M10162040054X0IWAR implements this per JEDEC JESD254 specification.
