The ATF16V8BQL-15JI is a 20-pin electrically erasable programmable logic device (EE PLD) from Microchip's 16V8 series, offering 8 macrocells and a propagation delay of 15 ns. This part is suited for address decoding, bus interface logic, and small state machines where the 15 ns speed provides comfortable timing margin against a 33 MHz system clock.
8 macrocells — logic capacity for small-scale integration
Eight macrocells give the ATF16V8BQL-15JI enough registered or combinatorial logic for a handful of D-type flip-flops, a 3-to-8 decoder, or a simple 4-state sequencer. The EE PLD architecture allows in-system or off-board reprogramming, so the logic function can be updated without replacing the device — useful during prototyping or field tweaks.
Microchip lists the ATF16V8BQL-15JI as Obsolete. For BOM lines that still call out this exact ordering code, supply is limited to independent-distributor surplus and broker inventory.
