Product details

Overview

5962-8976404MYA from Renesas Electronics is a military-grade 4K × 8 dual-port static RAM with fully asynchronous operation from either port, 35 ns maximum read cycle time, TTL-compatible 5 V ±10% supply, and MIL-PRF-38535 QML qualification for operation from –55°C to +125°C. It enables real-time data exchange between independent processors in avionics and radar signal processing systems.

For engineers reviewing the 5962-8976404MYA datasheet, 5962-8976404MYA pinout, 5962-8976404MYA application, or 5962-8976404MYA equivalent, this page delivers verified timing specs, military-grade DC/AC characteristics, package mapping to SB48 ceramic DIP, and validated alternatives for high-reliability embedded memory design.

Technical Context

The 5962-8976404MYA implements two independent address/data/control interfaces (left/right ports) with separate CE, OE, R/W, and address buses-enabling simultaneous but non-arbitrated access to shared memory. Each port supports full read/write capability with no wait states required.

It features automatic power-down via chip enable (CE), with standby current as low as 25 mA (TTL-level inputs) and 1.0 mA (CMOS-level inputs) across military temperature range. Battery backup data retention at 2 V is supported only in LA variants; the 5962-8976404MYA is an SA variant and does not support data retention below 4.5 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Size	4,096 × 8 bits - provides 32 KB of fast, non-volatile-retention SRAM for dual-processor buffering
Read Cycle Time	35 ns max - enables real-time data handoff between radar front-end and DSP subsystems
Supply Voltage	5.0 V ±10% - compatible with standard military 5 V power rails without regulation overhead
Operating Temp	–55°C to +125°C - qualified per MIL-PRF-38535 QML Class V for flight-critical environments
Power Dissipation	1.5 W max - meets thermal constraints in sealed avionics enclosures with conduction cooling
Package	48-pin sidebraze DIP (SB48) - hermetically sealed, leaded ceramic package for high-reliability PCB mounting
Input Leakage	≤10 µA max - ensures stable control logic behavior under radiation-induced leakage conditions

Pinout & Package

5962-8976404MYA is packaged in a 48-pin sidebraze ceramic DIP (SB48), measuring approximately 0.62 in × 2.43 in × 0.15 in, with all V_CC and GND pins requiring direct connection to system power/ground planes.

Pin/Terminal	Circuit Role	Design Meaning
A0L–A11L	Left port address inputs	12-bit address bus for left-side memory access; must be stable before t_AA (35 ns)
A0R–A11R	Right port address inputs	Independent 12-bit address bus enabling concurrent addressing on opposite port
I/O0L–I/O7L	Left port bidirectional data	8-bit data path; high-impedance when OE_L = VIH or CE_L = VIH
I/O0R–I/O7R	Right port bidirectional data	Electrically isolated 8-bit path; no contention unless both ports access same location
CEL, CER	Chip enable (left/right)	Active-low enables respective port; controls power-down mode (ISB1–ISB4)
OEL, OER	Output enable (left/right)	Active-low enables output drivers; high-impedance state prevents bus conflicts
R/WL, R/WR	Read/write control (left/right)	Active-low initiates write; high enables read; must be stable during address transitions
V_CC, GND	Power and ground	Multiple V_CC/GND pins require low-inductance decoupling for noise immunity in RF-dense platforms

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-port SRAM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
5962-9314901MXA	Same 4K × 8 size, 45 ns speed grade, identical SB48 package and MIL-PRF-38535 QML Class V rating	Slower timing limits use in <35 ns latency-critical paths (e.g., direct RF sample buffering)	Select when system timing budget allows 45 ns read cycle and cost optimization is prioritized
5962-9682601VXA	Higher density (8K × 8), 55 ns speed, PLCC-52 package (PLG52), same military temp and QML Class V	Requires PCB redesign due to different footprint and pinout; larger capacity suits extended buffer depth needs	Choose when memory expansion beyond 32 KB is required and PLCC assembly infrastructure exists

Compared with 5962-8976404MYA, 5962-9314901MXA trades 10 ns speed for broader availability and lower unit cost, while 5962-9682601VXA offers double capacity at the expense of layout change and relaxed timing-making the original optimal for latency-constrained, drop-in military upgrades.

FAQ

What is the maximum operating temperature range for the 5962-8976404MYA?

The 5962-8976404MYA is rated for operation from –55°C to +125°C ambient temperature, fully compliant with MIL-PRF-38535 QML Class V screening requirements for military and aerospace applications. This range is validated across all electrical parameters including read cycle time (35 ns max), supply current, and input/output voltage thresholds.

Does the 5962-8976404MYA support battery backup data retention?

No, the 5962-8976404MYA does not support battery backup data retention. It is an SA (Standard Power) variant; only LA (Low Power) versions such as 5962-9314901MXA include 2 V data retention capability. The 5962-8976404MYA requires minimum 4.5 V V_CC to maintain data integrity.

Which package type is used for the 5962-8976404MYA?

The 5962-8976404MYA uses a 48-pin sidebraze ceramic DIP (SB48) package, measuring approximately 0.62 in × 2.43 in × 0.15 in. This hermetically sealed, leaded ceramic package meets stringent reliability requirements for high-vibration, high-radiation, and long-lifecycle military deployments.

Can both ports of the 5962-8976404MYA access the same memory location simultaneously?

Yes, both ports can access the same memory location simultaneously, but the 5962-8976404MYA does not include on-chip arbitration logic. Users must implement external hardware or software arbitration to prevent data corruption-such as using semaphores or priority controllers-when concurrent writes occur.

What is the read cycle time specification for the 5962-8976404MYA?

The 5962-8976404MYA has a maximum read cycle time (t_RC) of 35 ns across the full military temperature range (–55°C to +125°C) and supply voltage (4.5 V to 5.5 V). This value is production-tested and guaranteed per MIL-PRF-38535 QML Class V requirements.
