The ATF22V10C-15PU is a 5V EE PLD from Microchip's 22V10 family, offering 10 macrocells with a 15 ns propagation delay. That 15 ns tpd is the combinatorial path budget from any input through the AND-OR array to the registered or combinatorial output — at a 5V supply, it gates the maximum system clock to about 33 MHz for registered state machines, and sets the address-to-output window for decode logic. The through-hole 24-DIP package (0.300-inch body) mates with standard 0.100-inch pitch sockets or solders directly into plated through-holes on legacy or low-volume boards.
10 macrocells — sizing the logic budget
Ten macrocells, each configurable as registered or combinatorial, sum to roughly 200–300 equivalent gate-equivalents depending on the product-term sharing. For a typical address decoder, a few chip-select glues, and a small state machine, the 22V10 fits without spilling into a larger CPLD. The EE reprogrammability means the part can be re-allocated across board variants with different JEDEC files — no mask charge, no OTP lock-in.
Microchip lists the ATF22V10C-15PU as Active product status. No NRND or EOL notice applies at this writing.
