Description
ATF16V8B-15PC is a CPLD (Complex Programmable Logic Device) from Atmel (now Microchip) in the ATF16V8B family. It provides 16 macrocells that can be wired together to implement small digital designs, including combinational logic, simple state machines, decoders, and other glue-logic functions. The device is designed for 5V operation and offers programmable I/O and interconnect resources suitable for compact, low-cost logic in embedded systems or hobby projects. The “-15” speed grade indicates roughly a 15 ns timing characteristic (faster or slower variants exist in the family). The “PC” suffix denotes the package type; exact pinout and package details are specified in the datasheet. As an older CPLD device, it is largely superseded by newer Microchip/Atmel CPLDs and small FPGAs, but it remains of interest for legacy designs or simple, small-footprint logic tasks. For precise specifications (I/O count, pinout, voltage, and programming method), consult the ATF16V8B-15PC datasheet and application notes.
