Product details
Overview
5962-8866206NA 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 5962-8866206NA datasheet, 5962-8866206NA pinout, 5962-8866206NA application, or 5962-8866206NA equivalent, this page delivers verified timing specs, military-grade thermal and reliability context, package mapping to 28-pin CDIP, and validated alternatives for legacy SRAM replacement in defense electronics design.
Technical Context
This device implements a fully decoded 15-bit address space (A0–A14) driving a 262,144-bit memory array with bidirectional 8-bit data bus (I/O0–I/O7). Control logic uses three independent enables-CS (chip select), WE (write enable), and OE (output enable)-to manage read/write cycles and high-impedance states per MIL-STD-883 timing requirements.
It supports two distinct power modes: active operation with dynamic current up to 135mA (typ.), and TTL-level standby (ISB = 20mA) triggered by CS HIGH. The L-version variant adds 2V data retention, but 5962-8866206NA is the S-version (standard power), confirmed by its ordering code suffix "DB" and absence of L-specific parameters in its AC/DC tables.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 32K × 8-bit (262,144 bits), fixed parallel interface with no internal refresh or burst logic |
| Access Time (tAA) | 25ns max - defines minimum address-to-valid-data delay under worst-case military temperature and voltage |
| Supply Voltage | 5V ±10% (4.5V–5.5V) - requires stable regulated rail; not compatible with 3.3V or mixed-voltage systems |
| Operating Temperature | –55°C to +125°C - qualified per MIL-STD-883 Class B, enabling use in missile guidance and airborne computing |
| Power Consumption | 135mA dynamic ICC (typ.) and 20mA ISB standby - dictates thermal management in sealed chassis |
| I/O Compatibility | TTL input thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V) and output drive (VOL ≤ 0.4V @ 8mA) - ensures direct interfacing with legacy 5V logic |
| Package | 28-pin 600-mil ceramic DIP (CD28) - hermetically sealed, leaded, and qualified for high-reliability board assembly |
Pinout & Package
5962-8866206NA is supplied in a 28-pin 600-mil ceramic dual in-line package (CD28), compliant with MIL-PRF-38535 and screened to Class B per MIL-STD-883. The package provides hermetic sealing, low moisture ingress, and thermal stability across extreme temperature cycling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A14 | Address Inputs | 15-bit unidirectional address bus; all must be stable before CS assertion for valid access |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit tristatable I/O; direction controlled by WE and OE; high-impedance when CS HIGH or OE/WE inactive |
| CS | Chip Select | Active-low enable; drives device into low-power standby (ISB) when HIGH; primary chip-level gating signal |
| WE | Write Enable | Active-low write control; initiates write cycle only when CS LOW; determines data capture timing window |
| OE | Output Enable | Active-low read control; enables output drivers only when CS and WE are HIGH and OE is LOW |
| VCC | Power Supply | +5V ±10% supply pin; requires local 0.1μF ceramic decoupling adjacent to pin |
| GND | Ground Reference | Signal and power ground return; must be low-inductance connection to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| MIL-STD-883 Class B qualification | Full screening including burn-in, temperature cycling, and mechanical shock - required for flight-critical hardware |
| 25ns military-grade access time | Guaranteed tAA ≤ 25ns across –55°C to +125°C - enables real-time data buffering in pulse-Doppler radar front ends |
| TTL-compatible I/O interface | No level-shifting needed with legacy 5V microcontrollers (e.g., Intel 80C86, Motorola 68000 derivatives) |
| Low-power standby mode | 20mA ISB current when CS HIGH - reduces system-level power draw during processor idle states |
| Hermetic 600-mil CDIP package | Robust against humidity, outgassing, and thermal stress - specified for 10+ year service life in sealed avionics enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-reliability SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8957201XA | Same 32K×8 organization and 25ns speed, but packaged in 28-pin SOJ (PJG28); lower thermal mass, no hermetic seal | Suitable for surface-mount boards where weight and volume are constrained, but not for high-humidity or vacuum environments | Select only if reflow compatibility and PCB density outweigh hermeticity requirements |
| 5962-9213501MXA | 256K × 4-bit organization (two devices needed for 8-bit bus); 35ns access; CDIP package; MIL-STD-883 Class B | Requires external byte-width logic; used where memory expansion flexibility or legacy 4-bit bus architecture exists | Choose when redesigning for multi-chip memory banks or maintaining compatibility with older 4-bit controller designs |
Compared with 5962-8866206NA, 5962-8957201XA offers SOJ packaging for higher-density layouts but sacrifices hermetic reliability, while 5962-9213501MXA trades single-chip simplicity for 4-bit granularity and slower timing - both require board-level validation for drop-in use in flight-critical systems.

FAQ
What is the full military specification compliance status of 5962-8866206NA?
5962-8866206NA is fully compliant with MIL-STD-883, Method 5005, Class B, including screening for thermal cycling, mechanical shock, vibration, and steady-state life testing. It meets the requirements of MIL-PRF-38535 for QML-38535 Class B flow, and its test report documentation is available upon request for DD Form 250 traceability.
Does 5962-8866206NA support battery backup data retention?
No, 5962-8866206NA is the standard-power (S) version and does not include battery backup capability. That feature is exclusive to the L-version variants (e.g., 5962-8866207NA), which specify 2V data retention and sub-5μW standby current. The 5962-8866206NA datasheet omits all data retention parameters, confirming its S-variant identity.
What is the maximum operating frequency supported by 5962-8866206NA?
5962-8866206NA does not operate on a clock signal; it is an asynchronous SRAM. Its maximum effective throughput is governed by tRC (read cycle time) of 25ns, supporting up to 40 MHz random-access bursts. Continuous sequential access may achieve higher average bandwidth, but no synchronous clock input or PLL is present.
Can 5962-8866206NA be used with modern 3.3V microcontrollers?
No - 5962-8866206NA requires a 5V ±10% supply and TTL-level signaling (VIH ≥ 2.2V, VOL ≤ 0.4V @ 8mA). Direct interface with 3.3V logic risks undervoltage I/O recognition and excessive current injection. Level translation (e.g., TXB0304 or discrete resistor networks) is mandatory, and such adaptation voids MIL-STD-883 qualification for the full system.
Is there a RoHS-compliant or "green" version of 5962-8866206NA available?
Yes - Renesas offers green (lead-free) versions of this part under updated ordering codes (e.g., 5962-8866206NAX), compliant with JEDEC J-STD-020 and RoHS Directive 2011/65/EU. These retain identical electrical and environmental specifications but use matte tin terminations and halogen-free molding compound; full qualification reports are provided with shipment.
