Product details
Overview
5962-8866204XA from Renesas Electronics is a military-grade 256K (32K × 8-bit) CMOS static RAM with 25ns access time, 5V ±10% supply, and MIL-STD-883 Class B compliance. It operates across –55°C to +125°C, supports TTL-compatible I/O, and features low-power standby (20mA) and battery backup data retention at 2V. It serves as main memory or buffer in avionics, radar processors, and hardened embedded controllers.
For engineers reviewing the 5962-8866204XA datasheet, 5962-8866204XA pinout, 5962-8866204XA application, or 5962-8866204XA equivalent, key selection criteria include military temperature qualification, 25ns read cycle timing, ceramic DIP package compatibility, and CS-controlled low-power standby behavior.
Technical Context
This device implements a full CMOS SRAM architecture with asynchronous random-access operation, direct TTL-level input/output interfaces, and dual standby modes: TTL-level (ISB = 20mA) and CMOS-level (ISB1 = 20mA) triggered by chip select logic. Address decoding is internal and fully decoded for all 15 address lines (A0–A14).
It supports two distinct write control schemes-WE-controlled and CS-controlled-with defined timing overlap requirements (tDW, tWHZ) and output high-impedance management during write transitions. Data retention at 2V is exclusive to the L-version, but 5962-8866204XA is an S-version part and does not support battery backup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 32K × 8-bit (262,144 bits), single-port asynchronous SRAM |
| Access Time (tAA) | 25ns max - defines minimum address-to-valid-data delay under military conditions |
| Supply Voltage | 5V ±10% - requires stable regulated 4.5–5.5V rail; no 3.3V operation |
| Operating Temperature | –55°C to +125°C - qualified per MIL-STD-883 Class B for sustained military deployment |
| Standby Current (ISB) | 20mA max - power savings when CS = HIGH, outputs tri-stated, system clock active |
| Input/Output Compatibility | TTL-compatible - interfaces directly with 74LS/ALS logic without level shifters |
| Package Type | 28-pin ceramic DIP (CD28, 600 mil) - hermetically sealed, high-reliability board mounting |
Pinout & Package
5962-8866204XA is supplied in a 28-pin ceramic dual in-line package (CD28, 600 mil), rated for military thermal and mechanical stress environments. The package provides hermetic sealing and lead finish suitable for high-reliability soldering processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A14 | Address Inputs | 15-bit address bus; fully decoded to select one of 32,768 memory locations |
| I/O0–I/O7 | Bi-directional Data Bus | 8-bit parallel interface; high-impedance when CS or OE inactive |
| CS | Chip Select | Active-low enable; controls standby entry/exit and output driver state |
| WE | Write Enable | Active-low signal enabling write cycles; must be coordinated with CS for valid write timing |
| OE | Output Enable | Active-low control for output drivers; allows read data gating independent of CS |
| VCC | Power Supply | +5V ±10% primary supply; powers core logic and I/O buffers |
| GND | Ground Reference | Signal and power return path; requires low-impedance PCB plane connection |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-reliability SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8957101XA | Same 32K×8 organization, 25ns speed, but uses SOJ package (PJG28) and lacks MIL-STD-883 Class B certification | Suitable for industrial-grade systems where hermeticity and full military screening are not mandated | Select when board space constraints favor surface-mount or cost targets exclude ceramic DIP premiums |
| 5962-9213501MXA | Higher density (1M × 8), 35ns access, CDIP package, MIL-STD-883 Class B qualified, but consumes 35mA ISB | Applicable where memory expansion is needed without redesigning address decoding logic | Choose when future-proofing capacity is prioritized over minimal power or strict 25ns timing compliance |
Compared with 5962-8866204XA, 5962-8957101XA trades military reliability for compact packaging, while 5962-9213501MXA increases capacity at the expense of access speed and standby current - making 5962-8866204XA optimal for size-constrained, timing-critical military edge nodes requiring proven Class B assurance.

FAQ
What is the maximum operating temperature range certified for the 5962-8866204XA?
The 5962-8866204XA is fully qualified for continuous operation from –55°C to +125°C per MIL-STD-883 Class B test requirements. This includes thermal cycling, steady-state burn-in, and parametric validation across the full range. Its ceramic DIP package and CMOS process ensure stable timing and leakage performance at both extremes, making it suitable for airborne and ground vehicle platforms exposed to uncontrolled ambient conditions. The 5962-8866204XA datasheet specifies no derating is required within this envelope.
Does the 5962-8866204XA support battery backup data retention?
No, the 5962-8866204XA does not support battery backup data retention. It is the standard-power (S) variant of the IDT71256 family; only the L-version (e.g., 5962-8866203XA) provides 2V data retention capability with microamp-level standby current. The 5962-8866204XA exhibits 20mA ISB in TTL-level standby mode and requires continuous 5V supply to maintain data integrity. System designers requiring battery-backed SRAM must select the L-suffix variant or implement external hold circuitry.
Which package type is used for the 5962-8866204XA?
The 5962-8866204XA is packaged exclusively in a 28-pin ceramic dual in-line package (CD28, 600 mil), as confirmed by Renesas' ordering information and pin configuration diagrams. This hermetically sealed package meets MIL-STD-1835 standards and is distinct from the SOJ (PJG28) and smaller DIP (SD28) variants offered in other members of the 71256 family. The CD28 footprint requires through-hole mounting and supports high-reliability soldering profiles compatible with military assembly standards.
Is the 5962-8866204XA pin-compatible with commercial versions of the IDT71256?
Yes, the 5962-8866204XA shares identical pinout, signal definitions, and electrical interface behavior with commercial and industrial variants of the IDT71256 (e.g., 71256S25DB), including A0–A14, I/O0–I/O7, CS, WE, OE, VCC, and GND assignments. However, due to its military screening, tighter AC parameter tolerances, and ceramic packaging, direct substitution into commercial designs requires validation of thermal, vibration, and long-term reliability requirements - the 5962-8866204XA is not a drop-in replacement unless those conditions are met.
What are the key timing parameters that define read cycle performance for the 5962-8866204XA?
The critical read cycle parameters for the 5962-8866204XA are tAA (address access time, 25ns max), tACS (chip select access time, 25ns max), tRC (read cycle time, 25ns min), and tOH (output hold from address change, 5ns min). These govern worst-case latency from address assertion or CS activation to valid data on I/O pins, and determine maximum sustainable read throughput. All are guaranteed across –55°C to +125°C and validated per MIL-STD-883 methods - unlike commercial variants, these values are production-tested, not characterization-only.
