5962-8981701XA

The Teledyne e2v 5962-8981701XA is a 256K-bit ultraviolet-erasable programmable read-only memory (UV EPROM) organized as 32K x 8 bits, supplied under a Standard Microcircuit Drawing (SMD) in a hermetic ceramic dual-inline package (CDIP). Derived from the CY7C279 family, this device operates from a single 5 V supply and features a JEDEC-standard pinout for seamless integration into legacy board designs. The quartz window integrated into the ceramic package allows complete erasure of stored content under controlled UV exposure, enabling field reprogrammability in prototyping and long-lifecycle systems. The CMOS architecture delivers low standby current and access-time characteristics consistent with high-reliability MIL-spec requirements, while the hermetic CDIP construction ensures robust environmental and mechanical protection.

This EPROM serves as non-volatile boot code or fixed-data storage in flight control computers, radar processors, secure military communication terminals, and weapon guidance subsystems where rad-tolerant performance and extended data retention are critical. As a component procured under the MIL-PRF-38535 framework, it carries full lot traceability, serialization, and screening appropriate to its device class, addressing the compliance demands of aerospace and defense acquisitions. Given the broad industry shift away from windowed ceramic EPROMs, this part inhabits a market segment with inherent obsolescence risk; Teledyne e2v’s sustained manufacturing commitment under the SMD provides a controlled pathway for replenishment spares and lifetime buys, reducing requalification burden for platforms that cannot be redesigned.
