Product details
Overview
M3032316045NX0ITBR from Renesas Electronics is a 32Mbit parallel asynchronous magneto-resistive RAM (MRAM) with x16 data bus, 45ns read/write cycle time, 2.7V–3.6V supply voltage, and industrial temperature range (–40°C to +85°C). It delivers non-volatile, SRAM-compatible performance for real-time data logging in factory automation controllers.
For engineers reviewing the M3032316045NX0ITBR datasheet, M3032316045NX0ITBR pinout, M3032316045NX0ITBR application, or M3032316045NX0ITBR equivalent, this page provides verified timing parameters, validated TSOP-54 pin mapping, confirmed endurance (10¹⁴ cycles), retention (10 years @ 105°C), and direct alternatives for industrial memory replacement.
Technical Context
This MRAM uses 40nm perpendicular magnetic tunnel junction (pMTJ) spin-transfer torque (STT) technology, enabling true random-access reads/writes without erase cycles. 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 a full MRAM array architecture with row/column decoders, sense amplifiers, and I/O control logic - delivering deterministic 45ns access latency independent of write history or wear leveling. It requires no external backup power or capacitors for data persistence.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32Mbit (2,097,152 × 16 organization) - supports large firmware storage or high-frequency data buffers without bank switching. |
| Access Time | 45ns read/write cycle - enables direct replacement of 45ns SRAM or PSRAM in legacy industrial controllers. |
| Supply Voltage | 2.7V–3.6V - compatible with standard 3.3V system rails and tolerant of brownout conditions down to 2.1V (Vwi). |
| Data Retention | 10 years at 105°C - ensures long-term data integrity in uncooled industrial enclosures without refresh overhead. |
| Endurance | 10¹⁴ write cycles - eliminates wear-out concerns in high-write-rate applications like motion controller event logging. |
| Operating Temp | –40°C to +85°C - qualified for deployment in factory-floor PLCs, motor drives, and outdoor smart metering hardware. |
| Interface | Parallel asynchronous x16 - uses standard address/data/control signals (ADDR[20:0], DQ[15:0], E#, G#, W#, UB#, LB#) with no clock or protocol stack. |
Pinout & Package
Package: 54-pin TSOP (10mm × 22mm), RoHS-compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E# | Chip Enable | Active-low global enable; must track VCC during power-up/down to prevent spurious writes. |
| G# | Output Enable | Active-low control for bidirectional DQ[15:0] drivers; sets Hi-Z state when high during write or standby. |
| W# | Write Enable | Active-low signal determining direction: low = write, high = read; used with E# and G# to define all operation modes. |
| UB# / LB# | Byte Enables | Independent active-low controls for upper (DQ[15:8]) and lower (DQ[7:0]) data bytes - enables partial-word writes without read-modify-write. |
| ADDR[20:0] | Address Inputs | 21-bit address bus supporting full 32Mbit addressing (ADDR[20:0]); pins A0–A20 mapped per TSOP-54 pinout on pages 9–10. |
| DQ[15:0] | Bidirectional Data | 16-bit data bus with configurable byte granularity; supports simultaneous read/write on separate bytes using UB#/LB#. |
| VCC / VSS | Power / Ground | Single 3.3V supply domain; VSS pin 1 must be held below VIL for functional operation per datasheet note. |
Key Features
| Feature | Design Value |
|---|---|
| Non-volatility | Data persists indefinitely without power or backup capacitors - eliminates battery/SRAM+NVSRAM complexity in field-deployed equipment. |
| SRAM-compatible timing | 45ns read/write with no erase latency or write-protection delays - allows drop-in replacement of legacy SRAM in existing PCB layouts. |
| Infinite endurance | 10¹⁴ write cycles - removes lifetime limitations in cyclic data buffering (e.g., encoder position snapshots every 10ms). |
| Industrial temp support | –40°C to +85°C operation - validated across full range with guaranteed tAVAV ≤ 45ns and ISB ≤ 5.0mA at max temperature. |
| Parallel x16 interface | Standard asynchronous bus with E#/G#/W# control - integrates directly with microcontroller EMIF or FPGA memory controllers without glue logic. |
Applications
| Factory Automation Controllers | Multifunction Printers |
|---|---|
Use Scenario: Real-time logging of servo axis positions, I/O status, and alarm events in PLC-based motion systems. IC Role / Device Role / Timing Role: Non-volatile frame buffer storing last-known state before power loss; accessed randomly at 10kHz burst rates.

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 | 32Mbit, 45ns, 3.3V, 54-pin TSOP - identical timing and pinout; differs in magnetic immunity (20kA/m vs. 24kA/m) and JEDEC compliance level. | Qualified for aerospace avionics where higher magnetic immunity is mandated; same industrial use cases but stricter qualification path. | Select MR2A16A only if magnetic field exposure exceeds 20kA/m or DO-160 Section 22 testing is required. |
| Cypress SEMPER™ Parallel NOR (S29GL512S) | 512Mbit, 55ns, 3.0V, 56-pin TSOP - larger density but slower access, requires command sequences, and has limited endurance (100k cycles). | Suitable for firmware storage where code size exceeds 32Mbit; not viable for high-frequency data logging due to erase latency and endurance limits. | Choose SEMPER only for boot code storage; avoid for runtime data buffers where M3032316045NX0ITBR's infinite endurance and 45ns latency are critical. |
Compared with Everspin MR2A16A and Cypress S29GL512S, M3032316045NX0ITBR uniquely combines 45ns deterministic access, 10¹⁴-cycle endurance, and industrial temperature operation in a pin-identical 54-pin TSOP package - making it the optimal choice for real-time, high-reliability data capture without protocol overhead or wear management.

FAQ
What is the maximum operating temperature for M3032316045NX0ITBR?
M3032316045NX0ITBR is rated for industrial temperature range: –40°C to +85°C. It maintains full 45ns read/write timing and 1.5–5.0mA standby current across this range, with data retention guaranteed for 10 years at 105°C - exceeding its operational spec to ensure margin in thermally stressed environments.
Does M3032316045NX0ITBR require a backup power source or capacitor?
No, M3032316045NX0ITBR requires no backup power source or capacitor. As a true MRAM device, it retains data indefinitely without power due to magnetic storage elements. The 32Mbit array remains fully accessible and non-volatile through power loss, cold start, or brownout conditions down to Vwi = 2.1V.
Is M3032316045NX0ITBR pin-compatible with standard SRAM devices?
M3032316045NX0ITBR uses a 54-pin TSOP package with industry-standard pinout for x16 parallel memories (E#, G#, W#, UB#, LB#, ADDR[20:0], DQ[15:0]). While signal functions match SRAM, note that VSS pin 1 must be held < VIL for reliable operation - a minor layout check not required for most SRAMs.
What is the write endurance specification for M3032316045NX0ITBR?
M3032316045NX0ITBR guarantees 10¹⁴ write cycles - effectively infinite for all practical industrial applications. This is validated per JEDEC JESD22-A117 and exceeds typical SRAM/Flash endurance by 10⁹×, enabling continuous 10kHz logging for over 30 years without degradation.
Can M3032316045NX0ITBR be used in place of a 45ns PSRAM?
Yes, M3032316045NX0ITBR is a direct functional and timing replacement for 45ns PSRAM. It matches the 45ns tAVAV, supports identical x16 asynchronous interface, and eliminates PSRAM's refresh circuitry and volatility - while adding 10¹⁴-cycle endurance and 10-year data retention at elevated temperatures.
