The ATF22V10C-10JI is a Microchip electrically-erasable programmable logic device (EE PLD) from the 22V10 family, offering a 10 ns propagation delay (tpd) from input to combinatorial output. This speed grade places it in the standard-performance tier for 5V PLDs — the 10 ns figure defines the maximum system clock frequency and the timing margin for registered logic paths. With 10 macrocells, it handles small-scale glue logic, address decoding, or state-machine functions where the 5V supply rail is already present.
28-PLCC footprint and rework
The device is supplied in a 28-lead PLCC (J-Lead) package, measuring 11.51 x 11.51 mm. The J-lead form factor is surface-mount but requires a PLCC socket or a reflow profile compatible with the lead bend. For rework, a hot-air nozzle sized to the 28-PLCC body is recommended — the J-leads are less accessible to a standard soldering iron tip than gull-wing packages.
Microchip lists the ATF22V10C-10JI as obsolete.
