QP7C199-25DMB

The Teledyne e2v QP7C199-25DMB is a high-reliability 32K x 8-bit CMOS static random-access memory (SRAM) in a hermetic ceramic dual in-line package (CDIP). Built around the CY7C199 family architecture and screened to the manufacturer’s QP/HiRel grade, it provides fully asynchronous operation with an access time as fast as 25 ns. The device operates from a single 5 V supply and incorporates a low-power CMOS design with static memory cells, eliminating the need for external clocks or refresh circuitry. Its CDIP package ensures robust environmental isolation, supporting stable performance over extended industrial temperature ranges and in mechanically demanding installations.

Typical deployments include flight computers, guidance and navigation processors, secure communications payloads, and ruggedized data acquisition systems across aerospace, defense, and energy sectors. The QP designation signifies enhanced reliability screening, often including full military temperature range validation, burn-in, and component-level traceability aligned with high-reliability procurement requirements. This part serves as a form-fit-function replacement for standard commercial CY7C199 SRAMs, helping to mitigate obsolescence risk in long-lifecycle programs. The Teledyne e2v HiRel flow further guarantees controlled material sets, lot homogeneity, and extended product availability, making the component suitable for design-in where supply continuity and documented pedigree are critical.
