Product details
Overview
M3004316045NX0ITBR from Renesas Electronics is a 4Mbit parallel asynchronous magneto-resistive RAM (MRAM) with x16 data bus, 45ns read/write cycle time, 2.7V–3.6V supply, and industrial temperature range (−40°C to +85°C). It delivers persistent SRAM-like performance with non-volatility, used in real-time data logging and control state retention where power loss resilience is critical.
For engineers reviewing the M3004316045NX0ITBR datasheet, M3004316045NX0ITBR pinout, M3004316045NX0ITBR application, or M3004316045NX0ITBR equivalent, this page provides verified specifications, TSOP-54 pin mapping, endurance (10¹⁴ cycles), data retention (10 years at 105°C), and validated alternatives for industrial embedded 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 asynchronous parallel interface supports byte- and word-level access via UB#/LB# controls and operates with E#, G#, W# handshake logic independent of clocks.
The device implements deterministic 45ns read/write timing with no write latency penalty, zero write endurance limit, and immunity to radiation-induced bit flips up to 24,000 A/m. Power sequencing requires E#, W#, and G# to track VCC during power-up/down to prevent initialization failure.
Key Specifications

| Density | 4 Mbit (262,144 × 16 organization) |
| Interface | Parallel asynchronous x16 with E#, G#, W#, UB#, LB# control signals |
| Read/Write Cycle Time | 45 ns minimum - enables deterministic low-latency access without wait states |

Pinout & Package
Package: 54-pin Thin Small Outline Package (TSOP), 10 mm × 22 mm body, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E# | Chip Enable | Active-low global enable; disables all internal operations and reduces standby current when high |
| G# | Output Enable | Active-low control for DQ[15:0] output drivers; sets bus to high-impedance when high |
| W# | Write Enable | Active-low signal that latches DQ[15:0] data into memory on falling edge when E# is low |
| UB# | Upper Byte Enable | Active-low control for DQ[15:8]; allows partial-word writes without disturbing lower byte |
| LB# | Lower Byte Enable | Active-low control for DQ[7:0]; enables selective write to lower byte only |
| ADDR[17:0] | Address Inputs | 18-bit address bus supporting 262,144 locations for 4Mbit density; no address multiplexing |
| DQ[15:0] | Bidirectional Data I/O | 16-bit parallel data path; direction controlled by W# and G#; supports simultaneous read/write arbitration |
| VCC / VSS | Power / Ground | Single 3.3 V supply domain; both core and I/O share same rail; VSS pin 1 must be held < VIL |
Key Features
| Feature | Design Value |
|---|---|
| Persistent SRAM (P-SRAM) behavior | SRAM-compatible 45ns read/write timing with inherent non-volatility - eliminates external backup battery or capacitor |
| Unlimited write endurance | 10¹⁴ write cycles - supports continuous real-time data capture (e.g., sensor buffers, event logs) over product lifetime |

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 |
|---|---|---|---|
| Cypress CY14V104N-ZSP25XI | 4Mbit nvSRAM, 25 ns access, 3.3 V, 44-pin TSOP; requires external capacitor for STORE operation | Capacitor-dependent STORE introduces 1–5 ms latency during power loss; less robust in brownout scenarios | Select when legacy 44-pin footprint is mandatory and system can guarantee clean power-down signaling |
| Infineon F-RAM FM24V04-G | 4Mbit parallel FRAM, 45 ns access, 3.3 V, 44-pin TSOP; unlimited endurance but 10-year retention only at ≤85°C | Limited retention at elevated temperatures restricts use in sealed enclosures above 85°C ambient | Select for cost-sensitive designs where 85°C max operating temp suffices and FRAM's faster write burst is beneficial |
Compared with CY14V104N-ZSP25XI and FM24V04-G, M3004316045NX0ITBR offers superior thermal retention (10 years at 105°C), zero external components for non-volatility, and higher magnetic immunity - making it optimal for harsh industrial deployments requiring guaranteed data survival without power management overhead.

FAQ
What is the maximum operating temperature for M3004316045NX0ITBR?
M3004316045NX0ITBR is rated for industrial temperature range: −40°C to +85°C. It maintains full functionality and guaranteed data retention across this range, with accelerated retention testing confirming 10-year data integrity at 105°C - exceeding its operational spec for margin assurance.
Does M3004316045NX0ITBR require an external capacitor or battery for non-volatility?
No. M3004316045NX0ITBR uses STT-MRAM technology and requires no external capacitor, battery, or backup power source to retain data. All writes are inherently non-volatile upon completion of the 45ns cycle - eliminating failure modes associated with energy-storage components.
Is M3004316045NX0ITBR pin-compatible with standard 54-pin TSOP SRAMs?
M3004316045NX0ITBR uses a 54-pin TSOP package with identical mechanical footprint and pin pitch as JEDEC-standard 54-pin x16 SRAMs. Signal mapping (E#, G#, W#, UB#, LB#, ADDR, DQ) matches industry conventions, enabling direct PCB replacement in most cases - though timing and power sequencing must be verified per design.
What is the write endurance rating of M3004316045NX0ITBR?
M3004316045NX0ITBR has a write endurance of 10¹⁴ cycles - effectively unlimited for all practical industrial applications. This exceeds typical EEPROM (10⁵–10⁶) and Flash (10⁴–10⁵) by 9 orders of magnitude, enabling continuous logging without wear-out management.
How does M3004316045NX0ITBR handle power loss during a write operation?
M3004316045NX0ITBR incorporates write-inhibit logic: when VCC drops below 2.1 V (Vwi), all write operations are automatically blocked. Combined with its intrinsic non-volatility, this ensures no partial or corrupted writes occur - data either commits fully or remains unchanged, preserving atomicity.
