5962-9174402MXX

Overview

The Cypress Semiconductor Corp 5962-9174402MXX is a UV-erasable programmable read-only memory (UVPROM) integrated circuit. It provides a storage capacity of 256 kilobits, organized as 32K x 8 bits. The device utilizes CMOS technology and features a parallel memory interface with a typical access time of 40 ns. It is housed in a hermetically sealed, windowed ceramic dual in-line package (CDIP-28) designed for through-hole mounting.

Feature Summary

• Hermetically sealed ceramic construction with a quartz window for UV erasure
• CMOS technology ensuring low power consumption
• Parallel interface architecture for direct system integration

Applications

• Embedded systems requiring high-density non-volatile data storage
• Industrial control environments demanding reliable program storage
• Military or aerospace applications necessitating radiation-hardened or hermetic packaging standards

Procurement Notes

Verify the presence of the UV window on the component surface to confirm erasability. Ensure the ordering suffix matches the specific speed grade and package variant required. Confirm that the supplier provides traceability documentation suitable for regulated industries, as this part often serves critical infrastructure roles where batch consistency is mandatory.

Selection Notes

Select this component when hermetic sealing and UV erasability are required for field reprogramming. Compare access times against system clock speeds to ensure compatibility. Consider the physical dimensions of the CDIP-28 package for PCB layout constraints. Evaluate thermal management requirements associated with through-hole mounting in enclosed industrial enclosures.

Part Context

This part belongs to the military-grade memory family produced by Cypress Semiconductor. It represents a legacy solution for applications requiring robust, non-volatile storage that can be physically erased and rewritten using ultraviolet light. The CDIP-28 form factor distinguishes it from modern surface-mount alternatives, targeting specialized manufacturing processes.

Replacement Considerations

Direct replacements must match the 256Kbit capacity, 32Kx8 organization, and CDIP-28 windowed package. Verify equivalent access times and voltage specifications. Cross-reference with other manufacturers offering hermetic PROMs if Cypress supply is limited.
