15 ns propagation delay — timing budget for the logic path
The ATF22V10B-15NM/883 is a 15 ns EE PLD from Microchip's 22V10 family, offering 10 macrocells in a hermetic 28-CLCC package. The 15 ns propagation delay is the pin-to-pin speed through the device — it sets the maximum clock frequency and the timing margin in a combinatorial or registered logic path. For a 5V-only system, this part fits where a 22V10-class PLD is needed and the board already runs on a single 5V rail.
The 28-CLCC (ceramic leaded chip carrier) provides a hermetic seal, which is the standard package choice for military, aerospace, and downhole applications where moisture and wide temperature cycling are a concern. The package footprint is 11.45 x 11.45 mm, surface-mount, with J-bend leads that solder to a standard LCC land pattern.
For a program that qualified the 22V10 architecture years ago, this part remains a straight drop-in for production replenishment.
EE PLD — reprogrammable without UV erasure
This is the same programming interface as the rest of the ATF22V10B family, so existing programming fixtures and JEDEC files carry over without changes.
