Procurement for this order code is handled through independent distribution on a quoted-to-order basis.
15 ns propagation delay — timing budget for legacy glue logic
The ATF16V8B-15PI is an 8-macrocell electrically erasable programmable logic device (EE PLD) from Microchip's 16V8 family, specified with a 15 ns propagation delay (tPD). This 15 ns speed grade sets the timing floor for registered-output and combinatorial paths.
20-pin PDIP — board footprint and rework
The 20-pin PDIP package (0.300 inch body width, 7.62 mm row spacing) is a through-hole footprint. For rework or breadboard prototyping, the PDIP package is straightforward to handle with a manual soldering iron or a desoldering station. No special hot-air profile or moisture bake is required.
EE PLD architecture — reprogrammable, no OTP lock
The electrically erasable (EE) programmable logic array allows the device to be erased and reprogrammed in-system or in a programmer. This contrasts with OTP or fuse-based PLDs that cannot be changed after programming. The eight macrocells provide up to eight registered or combinatorial outputs. Each macrocell can be configured as a D-type flip-flop with programmable clock and reset, or as a combinatorial logic function.
