Product details
Overview
5962-8866203NA 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 chip-select standby power of 20mA (typ.) for system-level power savings in avionics and ruggedized control systems.
For engineers reviewing the 5962-8866203NA datasheet, 5962-8866203NA pinout, 5962-8866203NA application, or 5962-8866203NA equivalent, key selection criteria include military temperature operation, 25ns read cycle timing, ceramic DIP package compatibility, and battery-backed data retention capability in low-power variants - all critical for legacy defense electronics sustainment and high-reliability embedded memory upgrades.
Technical Context
The 5962-8866203NA implements a full CMOS static RAM architecture with asynchronous random-access operation, direct TTL-level input/output interfaces, and dual standby modes: TTL-level (ISB) and CMOS-level (ISB1). Its address decoder drives a 262,144-bit memory array with independent WE/CS/OE control logic enabling precise read/write cycle management.
Timing is governed by strict military-grade AC specifications: tRC = 25ns max, tAA = 25ns max, tACS = 25ns max, and tCHZ = 11ns max at VCC = 5.0V ±10%. The device guarantees data retention down to 2V (L-version only), though 5962-8866203NA is the standard-power S-variant per ordering code DB (CD28 ceramic DIP).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 32K × 8-bit (262,144 bits), byte-wide parallel interface |
| Access Time (tAA) | 25ns maximum - enables integration into 40MHz bus systems without wait states |
| Supply Voltage | 5V ±10% - compatible with legacy 5V TTL/CMOS logic rails and military power supplies |
| Operating Temperature | –55°C to +125°C - qualified per MIL-STD-883 Class B for airborne, ground vehicle, and missile guidance systems |
| Power Consumption | 135mA dynamic ICC (max), 20mA ISB standby - supports thermal design in conduction-cooled chassis |
| Input/Output Compatibility | TTL-compatible VIH/VIL thresholds - eliminates level-shifting requirements in mixed-logic systems |
| Package Type | 28-pin 600-mil ceramic DIP (CD28) - hermetically sealed, leaded, and board-mountable per MIL-STD-202 |
Pinout & Package
5962-8866203NA is housed in a 28-pin 600-mil ceramic dual in-line package (CD28), compliant with MIL-STD-202 and MIL-STD-883 mechanical test requirements. The package provides hermetic sealing, high thermal stability, and long-term reliability under shock/vibration stress.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A14 | Address Inputs | 15-bit address bus accepting full 32K-word range; CMOS inputs with VIH ≥2.2V, VIL ≤0.8V |
| I/O0–I/O7 | Bi-directional Data Bus | 8-bit TTL-compatible data path; high-impedance when CS HIGH or OE HIGH during reads/writes |
| CS | Chip Select | Active-low enable; asserts memory array and I/O drivers; initiates standby mode when HIGH |
| WE | Write Enable | Active-low write control; latches data on falling edge when CS is LOW |
| OE | Output Enable | Active-low output gate; controls data bus drive during read cycles only |
| VCC | Power Supply | +5V ±10% primary supply; decoupling required per MIL-STD-1399 for transient immunity |
| GND | Ground Reference | Signal and power return; requires 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 testing for flight-critical use |
| Asynchronous SRAM architecture | No clock required - simplifies timing design in deterministic real-time control subsystems |

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, but 35ns access time and SOJ packaging (PJG28) | Limited to surface-mount assembly; lacks ceramic DIP mechanical robustness for high-vibration platforms | Select only if PCB redesign supports SOJ footprint and vibration environment is moderate |
| 5962-9213201MCA | 256K × 4-bit organization (two devices needed for byte-wide interface); 25ns speed; CD28 package | Requires external byte-enable logic and doubled board area; higher interconnect complexity | Consider only when existing designs already use 4-bit-wide memory buses or require redundancy partitioning |
Compared with 5962-8866203NA, 5962-8957201XA trades mechanical ruggedness for smaller footprint, while 5962-9213201MCA increases layout complexity to achieve identical timing in a different data-width architecture - making 5962-8866203NA the optimal choice for drop-in replacement of legacy 28-pin ceramic SRAMs in flight-qualified hardware.

FAQ
What is the operating temperature range certified for 5962-8866203NA?
The 5962-8866203NA is fully qualified for operation from –55°C to +125°C per MIL-STD-883 Class B environmental testing. This includes temperature cycling, steady-state bake, and thermal shock validation - confirming suitability for engine bay, missile seeker, and space-qualified payload applications where extreme thermal gradients occur.
Does 5962-8866203NA support battery backup data retention?
No - 5962-8866203NA is the standard-power S-variant (not the L-version). Battery backup data retention down to 2V is exclusive to part numbers ending in "L" (e.g., 5962-8866203LA). The 5962-8866203NA draws 20mA in standby (ISB) and does not implement the ultra-low-power retention circuitry found in L-variants.
Which package type does 5962-8866203NA use, and is it hermetically sealed?
The 5962-8866203NA uses the 28-pin 600-mil ceramic dual in-line package (CD28), which is hermetically sealed per MIL-STD-883 Method 1014. This construction prevents moisture ingress and ensures long-term reliability in high-humidity, salt-fog, or vacuum environments typical of naval and aerospace deployments.
Is 5962-8866203NA pin-compatible with earlier IDT-branded 71256S25DB devices?
Yes - 5962-8866203NA is the Renesas-manufactured successor to the IDT 71256S25DB, maintaining identical pinout, timing, electrical specs, and CD28 packaging. Renesas acquired IDT's memory business and continues production with full form-fit-function equivalence and updated MIL-STD-883 revision compliance.
What are the DC supply voltage limits and tolerance for 5962-8866203NA?
The 5962-8866203NA requires a nominal 5V supply with a specified operating range of 4.5V to 5.5V (±10%). Operation outside this window violates the Absolute Maximum Ratings and may cause data corruption or latch-up. System designers must ensure regulated 5V sources with adequate decoupling to meet transient response requirements per MIL-STD-1399.
