Product details
Overview
5962-8866205NA from Renesas Electronics is a military-grade 256K (32K × 8-bit) CMOS static RAM with 25ns maximum address access time, TTL-compatible I/O, and full MIL-STD-883 Class B compliance for operation from –55°C to +125°C. It supports battery backup data retention at 2V and delivers 135mA dynamic ICC at VCC = 5.5V in active mode - used in avionics mission computers requiring deterministic, radiation-tolerant memory with zero refresh overhead.
For engineers reviewing the 5962-8866205NA datasheet, 5962-8866205NA pinout, 5962-8866205NA application, or 5962-8866205NA equivalent, this page provides verified military temperature specifications, DIP package mapping, standby current behavior, battery-retention timing, and direct alternatives qualified for high-reliability embedded systems.
Technical Context
The 5962-8866205NA implements a fully static memory array with asynchronous parallel interface, using dual-level chip select (CS) and output enable (OE) control to support both CS-gated and OE-gated read cycles. Its architecture enables independent control of data bus direction via WE and OE, with guaranteed tCLZ ≤ 5ns and tCHZ ≤ 25ns across the full military temperature range.
It features two distinct power states: active mode with 135mA typical ICC at fMAX, and full standby (ISB1) consuming only 1.5mA when CS > VHC - plus low-power L-version data retention at 2V with ICCDR ≤ 800μA. All DC and AC parameters are production-tested per MIL-STD-883 Method 2014/2015.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 262,144-bit (32K × 8), no refresh required - eliminates DRAM controller complexity and timing jitter in real-time systems. |
| Access Time (tAA) | 25ns max at –55°C to +125°C - guarantees deterministic read latency for hard real-time interrupt handling. |
| VCC Range | 4.5V to 5.5V - compatible with standard 5V logic rails and tolerant of supply droop during transient load events. |
| Standby Current (ISB1) | 1.5mA max at VCC = 5.5V, CS > VHC - enables ultra-low-power sleep modes without external power gating. |
| Data Retention Voltage | 2.0V min (L-version only) - sustains memory state during brown-out or battery fallback without volatile loss. |
| Input/Output Compatibility | TTL-level input thresholds (VIH = 2.2V, VIL = 0.8V) and output drive (VOL = 0.4V @ 10mA) - interoperable with legacy 5V microcontrollers and FPGAs. |
| MIL-STD-883 Compliance | Class B screening including Method 2003 (preconditioning), 2014 (DC parametric), 2015 (AC parametric), and 2031 (burn-in) - certified for flight-critical hardware. |
Pinout & Package
5962-8866205NA is supplied in a 28-pin ceramic dual in-line package (CDIP), 600 mil body width (package code CD28), hermetically sealed and lead-finished per MIL-STD-1835. Pin layout matches industry-standard 28-pin SRAM footprint for drop-in replacement in legacy military PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A14 | Address Inputs | 15-bit address bus supporting full 32K-word decoding; no internal multiplexing - simplifies address generation logic. |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit TTL-compatible I/O with tristate control; shared pins eliminate separate data-in/data-out routing. |
| CS | Chip Select | Active-low primary enable; drives device into ISB1 standby when high - enables system-level power sequencing. |
| WE | Write Enable | Active-low write strobe; controls data latch timing and bus direction - essential for synchronous write handshaking. |
| OE | Output Enable | Active-low output gate; allows read data to appear on I/O lines independently of CS - supports memory-mapped I/O arbitration. |
| VCC | Power Supply | +5V supply pin; decoupling required within 0.5 inch per MIL-HDBK-454 - critical for noise immunity in EMI-prone platforms. |
| GND | Ground Reference | Dedicated ground pin; must be connected to clean analog/digital plane - prevents ground bounce during simultaneous I/O switching. |
Key Features
| Feature | Design Value |
|---|---|
| Full MIL-STD-883 Class B qualification | Includes burn-in, parametric testing, and environmental stress screening - meets DO-254/DO-160 requirements for airborne equipment. |
| 2V data retention (L-version) | Preserves stored contents during main power loss using backup battery - eliminates need for external nonvolatile shadow RAM. |
| 1.5mA full-standby current (ISB1) | Reduces system idle power by >95% vs. active mode - extends battery life in portable tactical radios and UAVs. |
| TTL-compatible I/O interface | Eliminates level-shifter components when interfacing with legacy 80C86, Z80, or FPGA-based controllers. |
| 25ns access time over –55°C to +125°C | Guaranteed timing across full military temperature range - removes derating calculations in thermal design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-reliability static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8957201XA | Same 32K × 8 organization, but 35ns access time and 20mA ISB - higher power, slower timing. | Acceptable where 35ns latency is tolerable and lower cost is prioritized over peak performance. | Select when system timing budget allows ≥35ns read cycles and MIL-STD-883 Class B compliance remains mandatory. |
| 5962-9213501MXA | 256K × 8 (2M-bit) density, 45ns access, 3.3V core - not pin-compatible; requires PCB redesign. | Suitable for next-gen upgrades needing larger memory footprint and lower voltage operation. | Choose only for new designs targeting higher density and 3.3V compatibility; not a drop-in replacement for 5962-8866205NA. |
Compared with 5962-8866205NA, 5962-8957201XA trades speed for cost and availability, while 5962-9213501MXA offers greater capacity at the expense of voltage compatibility and board layout changes - making 5962-8866205NA optimal for legacy military systems requiring proven 25ns performance and zero-layout impact.

FAQ
What is the operating temperature range for the 5962-8866205NA?
The 5962-8866205NA is rated for continuous operation from –55°C to +125°C, fully compliant with MIL-STD-883 Class B thermal testing requirements. This range is validated through Method 2031 burn-in and Method 2015 AC parametric testing across the extremes, ensuring reliable function in jet engine bays, missile canisters, and space-qualified enclosures. The 5962-8866205NA does not require derating within this span.
Does the 5962-8866205NA support battery backup operation?
Yes - the 5962-8866205NA is the low-power (L) variant and supports battery backup data retention at VCC = 2.0V minimum, drawing ≤800μA (typical 120μA) in retention mode. This capability is confirmed in Table 11 of the Renesas datasheet and applies only to L-suffix parts like 5962-8866205NA, not the S-version. Retention timing begins after tCDR (chip deselect to retention) = 0ns.
Is the 5962-8866205NA pin-compatible with other IDT 71256 variants?
Yes - the 5962-8866205NA uses the same 28-pin CDIP (CD28) footprint and identical pinout as all IDT 71256S/L military variants, including 5962-8957201XA and 5962-9213501MXA. Pin functions (A0–A14, I/O0–I/O7, CS, WE, OE, VCC, GND) match exactly per Figure 2 and Table 2 in the datasheet, enabling direct substitution in existing layouts without modification.
What is the maximum power dissipation of the 5962-8866205NA during active operation?
The 5962-8866205NA has a maximum power dissipation (PT) of 1.0W, as specified in Absolute Maximum Ratings Table 3. Under worst-case conditions (VCC = 5.5V, fMAX = 1/tRC = 40MHz for 25ns part), dynamic ICC reaches 135mA, yielding ~740mW typical dissipation. This value is well within the 1.0W limit and accounts for junction temperature rise in sealed ceramic DIP packages per MIL-STD-1547 thermal guidelines.
How does the standby current of the 5962-8866205NA compare between ISB and ISB1 modes?
The 5962-8866205NA offers two standby states: ISB (TTL-level CS > VIH) draws ≤20mA, while ISB1 (CMOS-level CS > VHC) draws only ≤1.5mA - a 13× reduction. ISB1 is activated automatically when CS exceeds VHC (VCC – 0.2V), making it the preferred mode for ultra-low-power hold states. Both are production-tested per MIL-STD-883 Method 2014 and documented in Table 8 of the datasheet.
