12 ns propagation delay — timing closure for glue logic
The ATF22V10CZ-12XC is a 22V10-architecture EE PLD from Microchip, delivering a 12 ns propagation delay from input to combinatorial output. That 12 ns figure sets the ceiling for the logic path timing — a registered output clock-to-output is typically a few nanoseconds faster, but the combinatorial tPD is the number to budget in a critical path. Ten macrocells provide enough fabric to absorb a handful of address decoders, state-machine next-state logic, or bus-interface gating without resorting to a larger CPLD.
Microchip lists this device as Obsolete. The formal last-time-buy window has passed, meaning the only channel for this exact order code is surplus inventory or broker-sourced stock.
5V-only rail — legacy supply consideration
The ATF22V10CZ-12XC requires a 5V supply for both the core and I/O. This is a 5V-only device — no internal regulator for 3.3V operation.
