Product details
Overview
5962-8855206UA from Renesas Electronics is a military-grade 256K (32K × 8-bit) CMOS static RAM with 25ns access time, 5V ±10% supply, and full MIL-STD-883 Class B compliance for operation from –55°C to +125°C - used in avionics data buffers, radar memory modules, and hardened flight control systems.
For engineers reviewing the 5962-8855206UA datasheet, 5962-8855206UA pinout, 5962-8855206UA application, or 5962-8855206UA equivalent, this page delivers verified timing specs, military temperature validation, TTL-compatible I/O behavior, standby power consumption, and package-specific pin mapping per official Renesas documentation.
Technical Context
The 5962-8855206UA implements a high-reliability CMOS memory array with address decoding, I/O control, and dual-mode standby: TTL-level chip select (ISB = 20mA) and CMOS-level full standby (ISB1 = 20mA), both triggered by CS high. It supports WE-controlled and CS-controlled write cycles with defined tWP, tDW, and tDH timing constraints.
Its functional block includes dedicated A0–A14 address inputs, bidirectional I/O0–I/O7 data lines, and three active-low control signals (CS, WE, OE) with guaranteed VIH/VIL thresholds (2.2V/0.8V at VCC = 5V). All DC and AC parameters are fully characterized across the –55°C to +125°C military temperature range per MIL-STD-883.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 32K × 8-bit (262,144 bits), byte-wide parallel interface |
| Access Time (tAA) | 25ns max - determines minimum read cycle latency in real-time control loops |
| Supply Voltage | 5V ±10% - compatible with legacy 5V TTL/CMOS system rails without level shifting |
| Operating Temperature | –55°C to +125°C - qualified per MIL-STD-883 Class B for sustained deployment in jet engine bays and space-qualified payloads |
| Standby Current (ISB) | 20mA max at VCC max - enables low-power hold mode during processor sleep without external power gating |
| Input/Output Compatibility | TTL-compatible VIH/VIL (2.2V/0.8V) - ensures direct interfacing with 74LS/ALS logic families |
| Package | 28-pin ceramic DIP (600 mil, CD28 code) - hermetically sealed for moisture resistance and thermal cycling endurance |
Pinout & Package
5962-8855206UA is supplied in a 28-pin ceramic dual in-line package (CD28, 600 mil width), hermetically sealed and qualified to MIL-STD-883 Class B for high-reliability military applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A14 | Address Inputs | 15-bit address bus accepting 0–32767 row/column selection; no internal latching - requires stable address before CS/WE assertion |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit TTL-compatible data path; high-impedance when CS high or OE high during reads, driven during writes |
| CS | Chip Select | Active-low enable; asserts memory access when low, forces standby (ISB/ISB1) when high - primary power management signal |
| WE | Write Enable | Active-low write strobe; controls data capture on I/O lines during CS low - defines write cycle boundaries with tWP and tDW |
| OE | Output Enable | Active-low output control; enables read data drive only when CS and OE both low - prevents bus contention in multi-SRAM systems |
| VCC | Power Supply | +5V ±10% main supply; powers core logic and I/O drivers - decoupling required within 0.5 inch per MIL-HDBK-454 |
| GND | Ground Reference | Signal and power return; must be connected to system ground plane with low-inductance path to minimize noise coupling |
Key Features

| Dual standby modes | ISB (TTL-level CS high) and ISB1 (CMOS-level CS high) reduce system power by >90% vs active operation - critical for battery-backed field-deployed units |
| 25ns military-speed access | Guaranteed tAA ≤25ns across –55°C to +125°C - enables deterministic response in fire-control interrupt handlers and digital signal acquisition pipelines |
| Hermetic 600-mil ceramic DIP | CD28 package provides zero moisture ingress and CTE matching to aluminum chassis - eliminates delamination risk in high-vibration airborne environments |
| TTL-compatible I/O levels | VIH = 2.2V min, VIL = 0.8V max at VCC = 5V - eliminates need for bus transceivers when interfacing with legacy MIL-STD-1553 or discrete logic controllers |
