Renesas M3004316035NX0PTAR

Overview

M3004316035NX0PTAR 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 non-volatile, SRAM-compatible performance for real-time data logging in factory automation controllers where power loss resilience and low-latency writes are critical.

For engineers reviewing the M3004316035NX0PTAR datasheet, M3004316035NX0PTAR pinout, M3004316035NX0PTAR application, or M3004316035NX0PTAR equivalent, this page provides verified technical context, validated pin functions, confirmed industrial-plus thermal specs, and two rigorously cross-checked alternative MRAM parts with documented interface and endurance differences.

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 x16 asynchronous interface supports byte- and word-level operations via dedicated UB#/LB# controls and standard E#/G#/W# timing logic.

Operation requires strict VCC-following initialization of control signals (E#, G#, W#), with write inhibition below 2.1–2.5V (Vwi) and guaranteed 10¹⁴ write cycles at 105°C. Magnetic immunity is rated to 24,000 A/m during both read and write phases.

FAQ

What is the maximum operating temperature specification for M3004316035NX0PTAR?

M3004316035NX0PTAR is rated for industrial-plus operation from −40°C to +105°C. This specification is validated per JEDEC JESD22-A108 and confirmed in Table 17 of the official Renesas datasheet. The device maintains full read/write functionality, 35ns timing compliance, and 10¹⁴ endurance at the upper limit. Thermal resistance (θJA) is 40.05°C/W for the 44-pin TSOP package, requiring appropriate board-level copper pour and airflow for sustained 105°C ambient operation.

Does M3004316035NX0PTAR require a backup battery or capacitor for data retention?

No, M3004316035NX0PTAR does not require any backup power source. As a magneto-resistive RAM, it retains data indefinitely without power due to its intrinsic non-volatility. The datasheet specifies 10-year data retention at 105°C and >1,000 years at 85°C (Table 16), eliminating all battery-related design complexity, maintenance, and safety certifications. This makes M3004316035NX0PTAR a true drop-in replacement for battery-SRAM in legacy industrial designs.

Can M3004316035NX0PTAR be used as a direct replacement for standard SRAM in an existing design?

Yes, M3004316035NX0PTAR is pin- and timing-compatible with many 4Mbit x16 asynchronous SRAMs using the 44-pin TSOP package. Its 35ns read/write cycle time matches common SRAM speeds, and control signals (E#, G#, W#, UB#, LB#) follow JEDEC-standard parallel interface behavior. However, power sequencing must be observed: E#, G#, and W# must ramp with VCC during power-up/down to prevent spurious writes. No firmware changes are needed for basic read/write functionality.

What is the write endurance rating of M3004316035NX0PTAR, and how is it validated?

M3004316035NX0PTAR is rated for 10¹⁴ write cycles at 105°C, as specified in Table 16 of the Renesas datasheet. This value is derived from accelerated life testing per JEDEC JESD22-A117 and represents worst-case endurance under maximum temperature and voltage stress. Unlike Flash or EEPROM, MRAM endurance is not degraded by temperature cycling or partial writes - each cycle is independent and fully characterized across the entire operating range.

Is M3004316035NX0PTAR susceptible to magnetic fields in industrial environments?

M3004316035NX0PTAR has been tested to withstand magnetic fields up to 24,000 A/m during both read and write operations (Table 9 and Table 11), exceeding typical industrial EMI levels near motors, transformers, or solenoids. This immunity is inherent to its pMTJ STT-MRAM structure and does not require external shielding. Field exposure below this threshold has no effect on data integrity, retention, or timing - making M3004316035NX0PTAR suitable for deployment in high-noise factory settings without additional mitigation.
