5 ns PLD for fast glue logic
The Microchip ATF22V10C-5JX is a 5 ns EE PLD from the 22V10 family, offering 10 macrocells in a 28-lead PLCC package. It runs on a 5V supply and is electrically erasable, so you can reprogram it on a standard device programmer without UV erasure.
Speed grade and logic capacity
The 5 ns propagation delay sets the timing floor for combinatorial paths — at this speed the part can handle 200 MHz+ toggle rates in registered mode, making it a fit for fast address decoding, state machines, and bus-interface logic where a slower 10 ns or 15 ns 22V10 would leave insufficient timing margin. Ten macrocells provide the logic equivalent of roughly 200–300 gate-array gates, enough for moderate-density functions like memory-mapped I/O decoding, simple arbiters, or control sequencers without needing a larger CPLD.
Package and supply rail
The 28-PLCC (J-Lead) package occupies an 11.51 mm square footprint and is socketable with a standard PLCC-28 socket for prototyping. The J-bend leads sit under the body, so the PCB land pattern must account for the lead stand-off and solder fillet inspection. A single 5V supply simplifies power distribution — no separate core or I/O rails. The part is specified for 5V ±10% operation, typical for legacy 5V logic families.
