Product details
Overview
5962-3829408MZA from Renesas Electronics is a military-grade 64K (8K × 8-bit) CMOS static RAM with 20ns maximum address access time, TTL-compatible I/O, single +5V supply operation, and battery backup data retention down to 2V (L-version). It serves as nonvolatile memory buffer in avionics control units requiring high-reliability, radiation-tolerant storage under –55°C to +125°C operation.
For engineers reviewing the 5962-3829408MZA datasheet, 5962-3829408MZA pinout, 5962-3829408MZA application, or 5962-3829408MZA equivalent, this page delivers verified military-spec timing parameters, MIL-STD-883 Class B compliance evidence, CERDIP package mechanical data, and direct alternatives for legacy SRAM replacement in defense electronics design.
Technical Context
The 5962-3829408MZA implements fully static asynchronous architecture-no clocks or refresh required-and uses dual chip select (CS1/CS2) with hierarchical power-down: CS2 asserts standby independently of CS1, enabling selective low-power mode entry. Its three-state outputs support bus sharing in multi-device systems.
It features two distinct operational modes: active read/write (CS1 = LOW, CS2 = HIGH, WE = HIGH for read) and standby (CS1 = HIGH or CS2 = LOW), with ISB current ≤2mA at VCC = 5V and TA = +25°C. The L-version adds data retention capability at VCC ≥2V, validated across full military temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 65,536 bits (8K × 8-bit); supports byte-wide parallel data interface without external demultiplexing. |
| Access Time (tAA) | 20 ns max (military grade); enables integration into 50 MHz synchronous bus systems with zero wait states. |
| Supply Voltage | +5.0 V ±10%; eliminates need for dual-rail regulation in legacy 5V logic systems. |
| Operating Temperature | –55°C to +125°C; qualified per MIL-STD-883, Class B for airborne and ground vehicle mission-critical use. |
| Data Retention Voltage | 2.0 V minimum (L-version only); sustains stored contents during brownout or battery-backup operation. |
| Standby Current (ISB) | 2.0 mA max at VCC = 5V; reduces system-level power budget in dormant phases of tactical radios. |
| I/O Compatibility | TTL input thresholds (VIH ≥2.2 V, VIL ≤0.8 V) and output drive (VOL ≤0.4 V @ 8 mA); ensures direct interfacing with 74LS/ALS logic families. |
Pinout & Package
5962-3829408MZA is supplied in a 28-pin 600 mil hermetically sealed CERDIP package (package code CD28), compliant with MIL-PRF-38535 and MIL-STD-883 screening requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A12 | Address Inputs | 13-bit binary address bus; selects one of 8,192 memory locations for read/write access. |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel data path; high-impedance when CS inactive or OE/WE assert disable conditions. |
| CS1, CS2 | Chip Select Inputs | CS1 active-low + CS2 active-high enables device; CS2 alone forces standby regardless of CS1 state. |
| WE | Write Enable Input | Active-low control: LOW initiates write cycle; HIGH enables read or high-Z output state. |
| OE | Output Enable Input | Active-low control: LOW enables data output drivers; HIGH places I/O pins in high-impedance state. |
| VCC, GND | Power Supply Terminals | Single +5V supply with dedicated ground; decoupling required within 0.5 inch of pins per MIL-HDBK-454. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed access | 20 ns tAA (max) at –55°C to +125°C ensures deterministic timing in real-time flight control loops. |
| Dual chip select architecture | CS2 overrides CS1 to force standby-enables hierarchical power management in multi-SRAM subsystems. |
| Battery backup retention | 2.0 V minimum VCC for data hold allows seamless transition to backup power in radar signal processors. |
| MIL-STD-883 Class B compliance | Includes burn-in, temperature cycling, and hermeticity testing-certified for space-qualified platforms. |
| TTL-compatible I/O | No level-shifting required when interfacing with legacy FPGAs, microcontrollers, or discrete logic in retrofit programs. |
Applications
| Avionics Flight Control Unit | Tactical Radio Baseband Processor |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8856901XA | Same 8K × 8 organization, 25 ns tAA, CD28 CERDIP, but no battery backup (S-version only). | Lacks 2V data retention; suitable only where continuous power is guaranteed. | Select when cost sensitivity outweighs backup requirement and 25 ns latency is acceptable. |
| 5962-9213701MXA | 64K × 8 configuration, 35 ns tAA, SD28 300 mil CERDIP, MIL-STD-883 Class B qualified. | Higher density but slower access; different pinout (SD28 vs CD28) requires PCB redesign. | Choose for increased memory depth where board space allows re-layout and timing budget permits 35 ns. |
Compared with 5962-3829408MZA, 5962-8856901XA trades data retention for lower unit cost and identical footprint, while 5962-9213701MXA offers double capacity at the expense of speed and mechanical compatibility-making the original the sole option for drop-in 20 ns, battery-backed, 600 mil CERDIP replacement.
