Product details
Overview
5962-3829407MXA from Renesas Electronics is a military-grade 64K (8K × 8-bit) CMOS static RAM with 20ns max address access time, TTL-compatible I/O, three-state outputs, and battery backup data retention down to 2V (L-version). It operates from a single 5V supply and supports standby power reduction via dual chip select logic, making it suitable for avionics, radar processors, and hardened embedded controllers requiring deterministic timing and extended data hold under brownout.
For engineers reviewing the 5962-3829407MXA datasheet, 5962-3829407MXA pinout, 5962-3829407MXA application, or 5962-3829407MXA equivalent, this page delivers verified military-spec SRAM parameters including MIL-STD-883 Class B compliance, -55°C to +125°C operation, 28-pin CERDIP package mapping, and direct substitution guidance for legacy IDT7164L20DB systems.
Technical Context
The 5962-3829407MXA 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, while CS1 alone enables low-power mode only when CS2 is active. Its memory array is organized as 8,192 words × 8 bits, with address decoding covering A0–A12.
Input and output buffers are designed for direct TTL interfacing (VIH = 2.2V min, VIL = 0.8V max), and all DC/AC specifications-including tAA = 20ns, tRC = 20ns, ISB ≤ 2mA (military), and ICC ≤ 110mA (active)-are guaranteed across the full -55°C to +125°C temperature range per MIL-STD-883 Class B test flow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 8K × 8-bit (65,536 bits), enabling byte-wide data bus interface without external multiplexing |
| Access Time (tAA) | 20 ns max at -55°C to +125°C - guarantees deterministic read latency in real-time control loops |
| Supply Voltage | 5.0 V ±10% - compatible with standard TTL/CMOS logic rails; no auxiliary voltage required |
| Standby Current (ISB) | ≤2 mA max (military grade) - enables ultra-low-power hold mode during processor sleep states |
| Data Retention Voltage | 2.0 V min (L-version only) - preserves memory contents during main supply collapse in safety-critical systems |
| Operating Temperature | -55°C to +125°C - qualified per MIL-STD-883 Class B for deployment in aerospace and defense platforms |
| Package | 28-pin 600-mil CERDIP (CD28) - hermetically sealed ceramic for moisture resistance and thermal stability |
Pinout & Package
5962-3829407MXA is supplied in a 28-pin 600-mil CERDIP (CD28) package with 0.6-inch width, ceramic body, and solderable leads. Pin 1 is marked by a dot; pin numbering follows standard DIP convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A12 | Address Inputs | 13-bit address bus accepting full 8K-word space; TTL-compatible thresholds ensure robust noise margin |
| I/O0–I/O7 | Bidirectional Data Bus | Three-state CMOS drivers support shared bus arbitration; high-impedance state activated by CS or OE control |
| CS1, CS2 | Chip Select Inputs | CS2 dominates power control: asserting CS2 LOW forces standby regardless of CS1; CS1 LOW + CS2 HIGH enables active mode |
| WE | Write Enable | Active-low signal controlling write cycle initiation; must overlap with valid CS and address setup |
| OE | Output Enable | Active-low gate for output drivers; independent of WE, allowing read-modify-write sequences |
| VCC, GND | Power Supply | Single 5V rail with decoupling recommended at package pins; no separate ground plane partitioning required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8856501XA | Same 8K×8 organization and 28-pin CD28 CERDIP, but rated for 25ns access and higher ISB (≤5 mA) | Lacks 2V data retention; suitable for non-battery-backed systems where speed margin is acceptable | Select when cost sensitivity outweighs need for lowest standby current or backup voltage capability |
| 5962-9213901MXA | Identical 20ns speed and 2V retention, but packaged in 28-pin SD28 (300-mil CERDIP) with different thermal profile | Smaller footprint limits board-level heat dissipation; requires layout revision for mechanical fit | Choose only if existing design uses SD28 socket or thermal constraints favor smaller ceramic package |
Compared with 5962-3829407MXA, 5962-8856501XA trades retention capability for broader speed availability, while 5962-9213901MXA maintains identical electrical specs but shifts thermal and mechanical behavior due to reduced package size-neither is pin-compatible without PCB modification.

FAQ
What is the guaranteed maximum access time for 5962-3829407MXA over its full operating temperature range?
The 5962-3829407MXA guarantees a maximum address access time (tAA) of 20 ns across the full -55°C to +125°C military temperature range, as validated per MIL-STD-883 Class B test conditions. This value is production-tested and applies to all devices shipped under this part number, ensuring deterministic timing in real-time avionics and defense subsystems where jitter-free memory response is mandatory. The 5962-3829407MXA does not require derating for temperature extremes.
Does 5962-3829407MXA support true battery backup operation, and what is the minimum retention voltage?
Yes, the 5962-3829407MXA (L-version) supports true battery backup operation with guaranteed data retention down to 2.0 V on VCC, as specified in the DC Electrical Characteristics table. This feature enables integration with primary lithium backup cells in mission-critical systems where main power may fail unexpectedly. The 5962-3829407MXA retains data indefinitely at this voltage with ISB ≤ 200 µA, eliminating need for external retention capacitors or supervisory circuits.
Is 5962-3829407MXA compliant with MIL-STD-883, and which test classes apply?
Yes, the 5962-3829407MXA is fully compliant with MIL-STD-883, Class B, including tests for steady-state life, temperature cycling, mechanical shock, vibration, and hermeticity. All units undergo full Class B screening per Method 5005, confirming suitability for flight-critical and ground-deployed defense hardware. The 5962-3829407MXA carries the appropriate QML-V qualification marking and is listed in the Defense Logistics Agency's Qualified Products List (QPL) for memory devices.
What package type and pin count does 5962-3829407MXA use, and is it hermetically sealed?
The 5962-3829407MXA uses a 28-pin 600-mil CERDIP (CD28) package with a ceramic body and metal lid, providing full hermetic sealing per MIL-STD-883 Method 1014. This construction ensures immunity to moisture ingress, resistance to thermal shock, and long-term reliability in high-humidity or vacuum environments. Pin 1 is marked by a laser-etched dot, and lead finish is solderable SnPb per MIL-STD-1276.
How does the dual chip select (CS1/CS2) architecture of 5962-3829407MXA reduce system power consumption?
The 5962-3829407MXA implements hierarchical chip select logic: asserting CS2 LOW forces immediate entry into standby mode (ISB ≤ 2 mA) regardless of CS1 state, while CS1 LOW + CS2 HIGH enables active operation. This allows system-level power managers to gate CS2 globally during idle periods, eliminating need for per-device enable sequencing. The 5962-3829407MXA achieves sub-2mA standby without external circuitry-critical for battery-limited platforms like UAVs and portable radios.
