5962-3829406MXA

Memory IC Overview

The Renesas Electronics Corporation 5962-3829406MXA is a military-grade asynchronous static random-access memory (SRAM) organized as 8K x 8 bits, providing a total storage capacity of 64 kbit. It operates on a single 5V supply with TTL-compatible inputs and outputs. The device features high-speed access times ranging from -20ns to -70ns depending on the specific speed grade. It supports reduced power standby modes and offers battery backup data retention at voltages as low as 2V. The component is housed in a 28-pin ceramic dual in-line package (CDIP) and complies with MIL-STD-883, Class B standards for harsh environment applications.

Memory IC Feature Summary

• Military compliance with MIL-STD-883, Class B specifications for reliability
• Low-power operation with battery backup data retention capability down to 2V
• TTL-compatible inputs and outputs for simplified system integration
• Fully static asynchronous circuitry requiring no clocks or refreshing

Memory IC Applications

Memory IC Procurement Notes

Verify the exact speed grade suffix corresponding to the required access time, as the base part number covers multiple performance variants. Confirm that the CDIP-28 ceramic package aligns with your board layout constraints. Ensure procurement channels are authorized due to the component's obsolete status and military classification requirements. Check for lead-free exemptions if RoHS compliance is strictly mandated for your assembly process.

Memory IC Selection Notes

Select this component when MIL-STD-883 Class B qualification is mandatory for the application. Choose based on the specific nanosecond access time required by the system timing constraints. Consider the 28-pin CDIP package size for mechanical fit. Evaluate the need for battery backup functionality if continuous power is not guaranteed in the operational environment.
