Product details
Overview
5962-3829409MZA from Renesas Electronics is a military-grade 64K (8K × 8-bit) CMOS static RAM with 20ns maximum address access time, TTL-compatible I/O, three-state outputs, and dual chip select (CS1/CS2) for low-power standby mode. It operates from a single 5V supply and supports battery backup data retention down to 2V (L-version). Used in avionics, radar processors, and hardened embedded systems requiring MIL-STD-883 Class B compliance.
For engineers reviewing the 5962-3829409MZA datasheet, 5962-3829409MZA pinout, 5962-3829409MZA application, or 5962-3829409MZA equivalent, this page delivers verified timing specs, military temperature range (-55°C to +125°C), DC/AC electrical characteristics, CERDIP package details, and direct alternatives for legacy SRAM replacement in defense electronics.
Technical Context
The 5962-3829409MZA implements fully static asynchronous operation-no clocks or refresh required-and uses dual chip select logic where CS2 powers down CS1 but not vice versa. Its standby current is 2mA max (S-version) or 1μA max (L-version) at military temperature extremes.
It features two independent chip select inputs enabling hierarchical memory mapping, write enable (WE) and output enable (OE) controls for precise bus timing, and TTL-level input thresholds (VIH = 2.2V min, VIL = 0.8V max) ensuring compatibility with legacy 5V logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 8K × 8-bit (65,536 bits), byte-wide parallel interface |
| Access Time (tAA) | 20ns max at -55°C to +125°C - enables real-time data buffering in high-speed signal processing |
| Supply Voltage | 5.0V ±10% - compatible with standard military 5V power rails without regulation overhead |
| Standby Current (ISB) | 2mA max (S) / 1μA max (L) - L-version supports battery-backed retention during main power loss |
| Data Retention Voltage | 2.0V min (L-version only) - maintains stored data during brownout or backup battery operation |
| Operating Temperature | -55°C to +125°C - qualified per MIL-STD-883, Class B for airborne and ground vehicle applications |
| Input/Output Compatibility | TTL-compatible (VIH ≥2.2V, VIL ≤0.8V) - interfaces directly with 74LS, 74F, and other 5V logic without level shifters |
Pinout & Package
5962-3829409MZA is supplied in a 28-pin 600 mil hermetically sealed CERDIP (CD28) package compliant with MIL-STD-883, Class B screening requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A12 | Address Inputs | 13-bit address bus supporting full 8K-word decoding; no internal latching |
| I/O0–I/O7 | Bi-directional Data Bus | Three-state TTL-compatible I/O lines; high-impedance when CS1 HIGH or CS2 LOW |
| CS1, CS2 | Chip Select Inputs | CS2 dominates CS1: CS2 LOW forces standby regardless of CS1 state; enables hierarchical memory banking |
| WE | Write Enable | Active-low control for write cycles; overlaps with CS1 LOW/CS2 HIGH to initiate write |
| OE | Output Enable | Active-low control for read data output; high-Z when deasserted, independent of CS states |
| VCC, GND | Power Supply | Single 5V supply with dedicated ground; decoupling required per MIL-STD-883 layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Dual Chip Select Architecture | CS2 forces standby even if CS1 is active - enables selective power gating in multi-bank memory systems |
| Battery Backup Data Retention | 2V minimum VCC retention voltage (L-version) - sustains memory contents during primary power interruption |
| MIL-STD-883 Class B Compliance | Full screening including burn-in, temperature cycling, and hermeticity testing - certified for flight-critical hardware |
| Three-State Output Drivers | Output leakage <5μA at VCC max - prevents bus contention in shared-memory multiprocessor architectures |
| Static Asynchronous Operation | No clock or refresh circuitry required - eliminates timing jitter and simplifies system-level clock tree design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-45ZSXI | 512K × 16-bit, 45ns access, 3.3V core, industrial temp only | Higher density but incompatible voltage and temperature grade; requires level-shifting and redesign | Select only if upgrading capacity and accepting non-military qualification |
| AS6C1008-20TIN | 128K × 8-bit, 20ns access, 5V, industrial temp, SOIC-28 | Same speed and voltage but lacks MIL-STD-883 screening and battery retention | Acceptable for commercial/industrial upgrades where military reliability is not mandated |
Compared with 5962-3829409MZA, CY62167EV30LL-45ZSXI offers greater density but sacrifices military qualification and introduces 3.3V/5V interface complexity, while AS6C1008-20TIN matches speed and voltage yet omits data retention and extended temperature capability critical for defense deployments.

FAQ
What is the qualified temperature range for 5962-3829409MZA?
The 5962-3829409MZA is qualified for operation from -55°C to +125°C per MIL-STD-883, Class B. This full military temperature range is explicitly guaranteed in the datasheet's Recommended Operating Conditions table and validated through temperature cycling and burn-in testing.
Does 5962-3829409MZA support battery backup operation?
Yes - the "L" suffix in 5962-3829409MZA denotes the low-power version with battery backup capability. It retains data at VCC as low as 2.0V, with data retention current specified at 15–300μA depending on temperature, per DC Electrical Characteristics Table 10.
What package type is used for 5962-3829409MZA?
5962-3829409MZA is packaged in a 28-pin 600 mil ceramic dual in-line package (CERDIP), designated CD28 in Renesas' ordering information. This hermetic package meets MIL-STD-883 mechanical and environmental requirements for harsh-environment deployment.
How does chip select logic work on 5962-3829409MZA?
5962-3829409MZA uses dual chip select inputs with priority: CS2 LOW forces standby regardless of CS1 state, while CS1 LOW alone enables operation only if CS2 is HIGH. This hierarchy allows selective power-down of memory banks in complex systems.
Is 5962-3829409MZA still recommended for new designs?
Although originally marked "Not recommended for new designs" in earlier revisions, that notice was formally removed in the February 2001 revision. The July 2020 Renesas rebranding confirms continued support, and Aetrix Electronics maintains active inventory and lifecycle management for 5962-3829409MZA.
