Product details
Overview
M10162040108X0ISAY from Renesas is a 16Mbit serial STT-MRAM (Spin-Transfer Torque Magnetoresistive RAM) with QSPI interface, 108MHz SDR operation, 1.71–2.0V supply, industrial temperature range (−40°C to +85°C), and 8-pad DFN (WSON) package. It delivers persistent SRAM-equivalent read/write timing with true non-volatility, used in real-time data logging and firmware storage for industrial controllers.
For engineers reviewing the M10162040108X0ISAY datasheet, M10162040108X0ISAY pinout, M10162040108X0ISAY application, or M10162040108X0ISAY equivalent, this page provides verified pin functions, JEDEC-compliant reset support, hardware/software write protection, 256-byte augmented storage array, and confirmed DDR/SDR mode behavior per Table 4 of the official datasheet.
Technical Context
The M10162040108X0ISAY implements a 40nm pMTJ STT-MRAM array with QSPI (4-4-4) interface supporting both SDR (108MHz) and DDR (54MHz) modes. Its command-address-data nomenclature (e.g., 4-4-4) defines full quad I/O usage for all instruction phases, and XIP (eXecute-In-Place) eliminates per-access command overhead for burst reads/writes.
It integrates dual power states - Deep Power Down (tEXDPD ≤ 400µs) and Hibernate (tEXHIB ≤ 450µs) - with full configuration retention and zero data loss. The device uses separate 256-byte Augmented Storage Array (addressable at 000000h–0000FFh) with per-section (32B) write protection, independent of main memory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 16 Mbit (2 MByte); supports full random access without erase cycles or wear leveling. |
| Interface | QSPI (4-4-4); enables simultaneous 4-bit command, address, and data transfer for maximum throughput. |
| Clock Speed | 108 MHz SDR; achieves ~432 MB/s effective read bandwidth in quad mode with no wait states. |
| Supply Voltage | 1.71 V – 2.00 V; compatible with modern low-voltage SoC I/O domains and reduces system power by >30% vs 3.3V SPI flash. |
| Operating Temp | −40°C to +85°C; qualified for industrial control cabinets and factory automation environments without derating. |
| Endurance | Virtually unlimited (>10¹⁵ cycles); eliminates lifetime concerns in high-write applications like event logging or parameter backup. |
| Data Retention | 20+ years at 85°C; guaranteed non-volatility without refresh or backup power, unlike battery-backed SRAM. |
Pinout & Package
Package: 8-pad DFN (WSON), 5.0 mm × 6.0 mm, moisture sensitivity level (MSL) 3, RoHS & REACH compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select (active-low) | Enables active mode when low; places device in standby (tri-state I/O, ISB current) when high. |
| WP# / IO[2] | Write Protect input / Bidirectional Data 2 | In SDR mode: hardware write protect for status register when WP# = low and SR[7]=1; in QPI mode: dedicated I/O line for quad data transfer. |
| SI / IO[0] | Serial Input / Bidirectional Data 0 | In SDR: command/address/data input on rising CLK edge; in QPI: part of 4-bit I/O bus for full-duplex transfers. |
| CLK | Clock input | Drives synchronous timing; SDR uses rising edge for input latching and falling edge for output; DDR uses both edges. |
| IO[3] | Bidirectional Data 3 | QPI-only pin; carries command/address/data in 4-4-4 mode; may be tied to VCC if unused in lower-pin-count modes. |
| SO / IO[1] | Serial Output / Bidirectional Data 1 | In SDR: data output on falling CLK edge; in QPI: full-duplex bidirectional data lane with deterministic timing per Table 4. |
| VCC | Core & I/O supply | Single 1.71–2.0V rail powers MRAM array, logic, and I/O buffers; requires local 100nF decoupling per datasheet Figure 6. |
| VSS | Ground | Common return for core and I/O; must be low-impedance connection to minimize switching noise on MRAM bitlines. |
Key Features
| Feature | Design Value |
|---|---|
| QSPI 4-4-4 Interface | Delivers 432 MB/s peak bandwidth with deterministic latency-no variable erase delays or program suspend required. |
| eXecute-In-Place (XIP) | Eliminates repeated command transmission for sequential accesses, reducing average read latency by up to 40% vs standard SPI. |
| Hardware + Software Write Protection | WP# pin + configurable Status Register bits (SR[7], SR[4:2]) enable layered protection for registers and memory blocks. |
| 256-byte Augmented Storage Array | Independent 8×32B sections with individual write-lock capability-ideal for storing calibration data, MAC addresses, or firmware keys. |
| JEDEC Reset Support | Guarantees known initial state after power-up or brown-out; eliminates need for external reset sequencing in resource-constrained 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 FM25V16-G | 16Mb F-RAM; 3.3V only (2.7–3.6V); max 40MHz SPI clock; no QPI or XIP support. | Limited to lower-bandwidth control-plane storage; lacks quad interface for high-throughput firmware loading. | Select when 3.3V system compatibility and ultra-low write energy (<1.5µJ/write) outweigh speed and voltage flexibility needs. |
| Infineon Technologies CY14V108N-ZSP25XI | 8Mb nvSRAM; 3.3V only; built-in lithium battery backup; 55ns async parallel interface-not SPI-compatible. | Requires PCB redesign for parallel bus; unsuitable for space-constrained designs using existing SPI footprints. | Select only for legacy async-bus systems needing battery-backed SRAM behavior-not for new SPI-based designs. |
Compared with FM25V16-G and CY14V108N-ZSP25XI, the M10162040108X0ISAY uniquely combines 1.8V operation, QSPI 4-4-4 bandwidth, and STT-MRAM endurance in a drop-in 8-pad DFN footprint-enabling direct upgrade from SPI flash without layout changes or voltage rail modifications.

FAQ
What is the operating voltage range for M10162040108X0ISAY?
The M10162040108X0ISAY operates from 1.71 V to 2.00 V only. This 1.8V nominal supply is fixed per its ordering code '1' (see Page 4, Table 1). It does not support 3.0V operation - that variant is designated with suffix '3' (e.g., M10162040108X0ISAR). Using voltage outside 1.71–2.00V violates absolute maximum ratings and may cause permanent damage to the M10162040108X0ISAY.
Does M10162040108X0ISAY support both SDR and DDR modes?
Yes, the M10162040108X0ISAY supports both Single Data Rate (SDR) at 108MHz and Double Data Rate (DDR) at 54MHz, as confirmed in the Features section (Page 1) and Table 4 (Page 12). DDR mode uses both clock edges for address/data transfer, while SDR uses only the rising edge for inputs and falling edge for outputs - behavior fully implemented in the M10162040108X0ISAY's command decoder and I/O drivers.
What package type is used by M10162040108X0ISAY?
The M10162040108X0ISAY uses an 8-pad DFN (WSON) package, 5.0 mm × 6.0 mm, as indicated by the 'WA' in its ordering code (Page 4) and confirmed in Figure 3 (Page 9). This matches the pinout shown in Table 2 (Page 7) and is distinct from the SOIC variant ('SA') - the 'Y' suffix denotes tray packing, not package type.
How is write protection implemented on M10162040108X0ISAY?
The M10162040108X0ISAY implements dual-layer write protection: hardware-based via the WP# pin (active-low, requires SR[7]=1 to activate), and software-based via Status Register bits SR[5] (Top/Bottom select) and SR[4:2] (block protect). Both mechanisms independently inhibit writes to memory and registers - verified in Section 11.1 (Page 17) and Table 12.
Is M10162040108X0ISAY pin-compatible with other devices in the Mxxxx204 family?
Yes, all Mxxxx204 variants - including M1004204, M1008204, and M1016204 - share identical 8-pad DFN (WA) and 8-pin SOIC (SA) footprints and pinouts (Figures 3 & 4, Page 9). The M10162040108X0ISAY is mechanically and electrically pin-compatible with M10042040108X0ISAY and M10082040108X0ISAY, enabling density upgrades without PCB revision.
