Product details
Overview
The 5962-8969002LA from Renesas Electronics is a military-grade 16K-bit (2K × 8) CMOS static RAM with 20ns access time, 2V data retention capability, TTL-compatible I/O, and full standby power mode. It operates across –55°C to +125°C, complies with MIL-STD-883 Class B, and is packaged in 24-pin ceramic DIP (SD24) for high-reliability avionics and defense systems.
For engineers reviewing the 5962-8969002LA datasheet, 5962-8969002LA pinout, 5962-8969002LA application, or 5962-8969002LA equivalent, this page delivers verified timing specs, military-grade DC/AC characteristics, battery-backed retention behavior, ceramic package mechanical data, and direct alternatives for legacy system sustainment and radiation-tolerant design.
Technical Context
This device implements fully static asynchronous operation-no clocks or refresh required-and uses advanced CMOS technology to eliminate alpha-particle soft-error susceptibility. Its dual-mode standby (TTL-level and CMOS-level) enables dynamic power scaling: ISB = 40mA at TTL-level CS deassertion, dropping to ISB1 = 0.1µA under CMOS-level control with VCC = 5V.
The 5962-8969002LA supports two distinct read cycles (OE-controlled and CS-controlled) and two write cycles (WE-controlled and CS-controlled), with guaranteed tRC = 20ns across full military temperature range. Data retention at 2V is validated per MIL-STD-883 Method 1017, requiring no external backup circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2K × 8-bit (16,384 bits), byte-wide parallel interface |
| Access Time (tAA) | 20ns max at –55°C to +125°C - guarantees real-time response in missile guidance and radar processing |
| Data Retention Voltage | 2.0V min - enables direct connection to lithium thionyl chloride batteries without regulation |
| Standby Current (ISB1) | 0.1µA typical at VCC = 5V - extends battery life to >10 years in unpowered storage |
| Operating Temperature | –55°C to +125°C - qualified per MIL-STD-883 Class B for space and tactical platforms |
| I/O Compatibility | TTL input thresholds (VIH = 2.2V, VIL = 0.8V) and output drive (VOH = 2.4V @ –4mA, VOL = 0.4V @ 8mA) |
| Package | 24-pin ceramic DIP (SD24), 0.300-inch width, hermetically sealed for moisture resistance |
Pinout & Package
24-pin ceramic dual in-line package (SD24), 0.300-inch body width, hermetic ceramic construction with solder-dip leads. Compliant with MIL-STD-1835C outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| I/O0–I/O7 | Bi-directional Data Bus | 8-bit TTL-compatible data path; high-impedance state when CS = HIGH or OE = HIGH during reads |
| CS | Chip Select | Active-low enable; drives device into low-power standby (ISB = 40mA) or ultra-low-power retention (ISB1 = 0.1µA) based on logic level |
| WE | Write Enable | Active-low control for write cycles; must overlap LOW CS to initiate write; defines tWP = 20ns minimum pulse width |
| OE | Output Enable | Active-low control for read output drivers; independent of WE, enabling read-modify-write sequences |
| VCC | Power Supply | +5.0V ±10% supply; supports full-speed operation and data retention down to 2.0V |
| GND | Ground Reference | Signal and power return; decoupling required within 0.5 inch of VCC pin per MIL-STD-883 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8774401XA | Same 2K×8 organization, 25ns access, but no 2V data retention; requires external backup controller | Limited to non-battery-backed systems where retention not required during power loss | Select when cost sensitivity outweighs retention requirement and board space allows discrete backup circuitry |
| 5962-9213901MXA | 20ns access, 2V retention, but plastic DIP (PTG24); not MIL-STD-883 qualified | Suitable for ground-test equipment or industrial controllers, not flight hardware | Choose only for lab prototypes or non-mission-critical subsystems where hermeticity and screening are unnecessary |
Compared with 5962-8969002LA, 5962-8774401XA lacks battery retention and requires additional support components, while 5962-9213901MXA sacrifices military qualification for lower cost-neither offers the full combination of 20ns speed, 2V retention, and MIL-STD-883 Class B compliance in a hermetic ceramic package.

FAQ
What is the maximum guaranteed access time for the 5962-8969002LA across its full military temperature range?
The 5962-8969002LA has a maximum guaranteed access time (tAA) of 20ns over the full –55°C to +125°C operating temperature range, as specified in the AC Electrical Characteristics table under "Military" grade conditions. This value is production-tested and applies to all units shipped, ensuring deterministic timing for hard real-time avionics software.
Does the 5962-8969002LA require external circuitry to maintain data during power loss?
No, the 5962-8969002LA does not require external circuitry for data retention during power loss. Its LA version supports intrinsic battery backup operation at VCC = 2.0V, drawing only 0.1µA to 0.5µA depending on temperature-enabling direct connection to primary lithium cells without regulators, supervisors, or diodes.
Is the 5962-8969002LA pin-compatible with commercial-grade IDT6116LA devices?
Yes, the 5962-8969002LA shares identical pinout, signal definitions, and electrical interface with commercial IDT6116LA variants (e.g., 6116LA20TDB), including A0–A10, I/O0–I/O7, CS, WE, OE, VCC, and GND. However, it uses the SD24 ceramic DIP package and undergoes MIL-STD-883 screening-mechanical compatibility is maintained, but thermal and reliability profiles differ.
What is the significance of the "Class B" qualification for the 5962-8969002LA?
Class B qualification per MIL-STD-883 means the 5962-8969002LA has undergone rigorous screening including steady-state life test, thermal cycling, mechanical shock, vibration, and internal visual inspection. This certification validates suitability for mission-critical defense systems where failure is not acceptable, such as flight control, weapons release, and secure comms.
Can the 5962-8969002LA be used in systems requiring RoHS compliance?
Yes, the 5962-8969002LA is a green part compliant with RoHS Directive 2011/65/EU and EU REACH regulations, as confirmed in the Renesas ordering information and datasheet revision history (updated April 2011). Lead-free terminations and halogen-free molding compound meet current environmental standards for defense procurement.
