5962-9459901MXA

Overview

The Simtek 5962-9459901MXA is a non-volatile RAM (NVRAM) circuit featuring a hybrid Flash and SRAM architecture. It provides a storage capacity of 8K words by 8 bits, organized as 64 Kbit. The device operates asynchronously with a maximum access time of 55 ns. It supports a voltage range of 4.5 V to 5.5 V and functions within an industrial temperature range of -55 °C to +125 °C. The component utilizes a ceramic leaded chip carrier (CLCC) package configuration for mounting.

Feature Summary

• Combines Flash memory for non-volatility with SRAM for high-speed random access operations.
• Supports asynchronous parallel interface for data transfer.
• Maintains data integrity across extended military-grade temperature ranges.

Applications

• Data logging systems requiring persistent storage without battery backup.
• Industrial control units needing rapid read/write cycles.
• Avionics equipment operating in extreme thermal environments.

Procurement Notes

Verify the specific suffix MXA against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with existing system voltage levels and interface requirements before procurement. Cross-reference the part number with current availability status as distribution channels may vary.

Selection Notes

Select this component when non-volatile storage with SRAM-like speed is required. Consider the CLCC package constraints for PCB layout. Verify that the 55 ns access time meets system timing requirements. Confirm the 4.5 V to 5.5 V supply range aligns with the target application power design.

Part Context

This part belongs to the standard microcircuit drawing series managed under MIL-HDBK-103AJ. It represents a specialized memory solution designed for ruggedized applications. The designation indicates compliance with specific military standards for reliability and performance in harsh conditions.

Replacement Considerations

Consult official substitution lists for equivalent NVRAM devices. Verify pinout compatibility and electrical specifications before replacing. Generic equivalents may not match the specific temperature or package requirements.
