The ATF22V10B-15GM/883 is an electrically erasable programmable logic device from Microchip's 22V10 family, delivering a 15 ns propagation delay from input to combinatorial output. That 15 ns figure sets the maximum clock frequency and the bus timing budget — in a 5V system running at 33 MHz or slower, the part has enough margin for registered logic without wait-states.
Hermetic 24-CDIP — the footprint for high-reliability builds
Housed in a 24-CDIP (0.300", 7.62mm) ceramic dual-in-line package, this part is a through-hole mount that mates with standard 0.600-inch-wide DIP sockets or solders directly into plated through-holes. The ceramic body and hermetic seal are specified for military/aerospace environments where moisture resistance and thermal cycling endurance are required. The package code /883 signals a MIL-STD-883 compliant flow — the part is screened to the full Class B or equivalent level.
10 macrocells, EE PLD — what the architecture delivers
Ten macrocells, each configurable as registered or combinatorial, give the designer 10 flip-flops plus sum-of-product logic. The electrically erasable cell means the part can be reprogrammed in-system or on the programmer without UV erasure — useful for prototyping and field-updateable glue logic. Supply is a single 5V rail; no second programming voltage is needed.
Microchip lists the ATF22V10B-15GM/883 as Active. There is no last-time-buy clock ticking, and no official successor has been announced — the 22V10 architecture is mature but still supported for legacy and high-reliability programs.
