Product details
Overview
M3004316035NX0PTAY from Renesas Electronics is a 4Mbit parallel asynchronous magneto-resistive RAM (MRAM) with x16 data bus, 35ns read/write cycle time, 2.7–3.6V supply, and industrial-plus temperature range (−40°C to +105°C). It delivers persistent SRAM-like performance with true non-volatility, infinite write endurance, and low-power operation-ideal for real-time data logging in factory automation controllers.
For engineers reviewing the M3004316035NX0PTAY datasheet, M3004316035NX0PTAY pinout, M3004316035NX0PTAY application, or M3004316035NX0PTAY equivalent, this page provides verified technical context, validated pin functions, confirmed operating parameters, and two rigorously cross-checked alternative MRAM options for industrial-grade non-volatile memory replacement.
Technical Context
This MRAM uses 40nm perpendicular magnetic tunnel junction (pMTJ) spin-transfer torque (STT) technology to achieve deterministic, high-speed writes without wear-out mechanisms. Its parallel asynchronous interface supports byte- and word-level access via dedicated UB#/LB# controls and standard E#/G#/W# command protocol.
The device implements full random-access behavior: reads and writes occur at any address with identical 35ns timing, no erase cycles, and zero latency penalty between successive operations. Internal architecture includes row/column decoders, sense amplifiers, and address control logic fully compatible with legacy SRAM bus protocols.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4Mbit (262,144 × 16 organization) |
| Access Time | 35ns read/write cycle - enables drop-in replacement for 35ns SRAMs without timing redesign |
| Supply Voltage | 2.7V–3.6V - compatible with standard 3.3V industrial power rails |
| Operating Temperature | −40°C to +105°C - qualified for extended-temperature industrial control environments |
| Data Retention | 10 years at 105°C - guaranteed non-volatility under worst-case thermal stress |
| Write Endurance | 10¹⁴ cycles - effectively unlimited for all embedded logging and configuration storage use cases |
| Interface Type | Parallel asynchronous x16 - requires no clock, no initialization sequence, direct CPU bus connection |
Pinout & Package
Package: 44-pin TSOP (10mm × 18mm), lead-free, RoHS/REACH compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E# | Chip Enable | Active-low global enable; must follow VCC during power-up/down to prevent corruption |
| G# | Output Enable | Active-low control for DQ[15:0] output drivers; high-Z when deasserted |
| W# | Write Enable | Active-low write strobe; determines direction of DQ bus (write when low, read when high) |
| UB# | Upper Byte Enable | Active-low control for DQ[15:8]; enables partial-word writes without affecting lower byte |
| LB# | Lower Byte Enable | Active-low control for DQ[7:0]; enables partial-word writes without affecting upper byte |
| ADDR[17:0] | Address Inputs | 18-bit address bus for 4Mbit density; no address multiplexing required |
| DQ[15:0] | Bidirectional Data I/O | 16-bit parallel data path; supports simultaneous read/write on separate bytes via UB#/LB# |
| VCC / VSS | Power / Ground | Single 3.3V supply domain; VSS pin 1 must be held < VIL for proper function |
Key Features
| Feature | Design Value |
|---|---|
| Non-volatility with SRAM timing | Retains data without backup power while delivering 35ns random-access read/write - eliminates battery/SRAM+flash hybrid designs |
| True random access | No erase blocks or page constraints; any address writable at any time, enabling real-time ring buffer and state variable storage |
| Industrial-plus temperature rating | Validated operation from −40°C to +105°C - suitable for enclosed motor drives and outdoor smart meters |
| Byte-selectable write capability | Independent UB#/LB# controls allow 8-bit updates without disturbing adjacent data - critical for atomic firmware parameter updates |
| High magnetic immunity | Withstands 24,000 A/m fields during read/write - robust in proximity to motors, solenoids, and transformers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-volatile parallel memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Everspin MR2A16A | 4Mbit, 45ns access, 3.3V, 44-pin TSOP - slower timing, same density and package footprint | Requires timing margin adjustment in 35ns-critical systems; otherwise pin-compatible | Select when system timing budget allows 45ns cycles and long-term supply continuity is prioritized over peak speed |
| Renesas M3004316045NX0PTAY | Same 4Mbit density, package, and voltage; 45ns access instead of 35ns - identical feature set and reliability specs | Drop-in replacement where 45ns timing suffices; shares same qualification, thermal, and magnetic immunity ratings | Choose for cost-optimized sourcing when 35ns performance is not required - identical footprint and firmware compatibility |
Compared with M3004316035NX0PTAY, MR2A16A trades 10ns speed for broader historical supply chain maturity, while M3004316045NX0PTAY offers identical reliability and packaging at relaxed timing - both preserve byte-select write capability and 105°C operation without layout changes.

FAQ
What is the maximum operating temperature for M3004316035NX0PTAY?
M3004316035NX0PTAY is rated for industrial-plus operation from −40°C to +105°C. This specification is validated per JEDEC standards and confirmed in Table 17 of the official Renesas datasheet revision dated June 27, 2023. The device maintains full 35ns timing and data retention compliance across this entire range.
Does M3004316035NX0PTAY require a power-on reset sequence?
No, M3004316035NX0PTAY does not require a software reset. However, hardware sequencing is mandatory: E#, W#, and G# signals must track VCC during both power-up and power-down transitions. Failure to follow this requirement risks data corruption, as specified in Section 15 (Device Initialization) of the datasheet.
Can M3004316035NX0PTAY be used as a direct replacement for standard SRAM?
Yes, M3004316035NX0PTAY is designed as a functional and pin-compatible replacement for 4Mbit ×16 35ns SRAMs. It accepts identical control signals (E#, G#, W#, UB#, LB#), uses the same address/data bus timing, and requires no firmware changes - though its non-volatility eliminates need for backup power circuits.
What is the write endurance rating of M3004316035NX0PTAY?
M3004316035NX0PTAY guarantees ≥10¹⁴ write cycles per memory location, as documented in Table 16 (Endurance and Data Retention). This exceeds typical SRAM endurance and eliminates wear-leveling requirements - making it suitable for continuous logging applications with high-frequency writes.
Which package type does M3004316035NX0PTAY use?
M3004316035NX0PTAY uses a 44-pin TSOP package (10mm × 18mm), as defined in the part number suffix 'TA' and confirmed in Pages 9 and 11 of the Renesas datasheet. This package supports only the 4Mbit density variant and is RoHS/REACH compliant.
