Description

ATF16V8B-15PC is an old Atmel CPLD (Complex Programmable Logic Device) in the 16V8B family. It provides 16 macrocells for implementing combinational logic and optionally registered outputs, in a non-volatile programmable device. The “-15” denotes a ~15 ns speed grade, and “-PC” indicates a Plastic DIP (28-pin) package. It operates from about 4.5–5.5V. Typical uses are glue logic, simple state machines, decoders, and signal conditioning between digital blocks. Programming is done with Atmel/Microchip’s programming software using a supported programmer; once programmed, the configuration is retained without power. The device is largely obsolete today, with newer CPLDs/FPGA families offering more I/O and features. For specifics on pinout, macrocell structure, and operating conditions, consult the official datasheet.

Features

Here are the core features of ATF16V8B-15PC (Atmel CPLD):
- 8 macrocells (8 programmable logic outputs)
- 16 user I/O pins
- Fully programmable interconnect/configurable logic (two-level AND/OR style)
- Non-volatile, one-time programmable (fuse-based) device
- Speed grade: -15 (approx. 15 ns)
- 5V operation; CMOS/TTL-compatible I/O
- 28-pin Plastic DIP/leadframe package (PC suffix specifies package type)
- Tri-state (output enable) capability on I/O
- Suitable for glue logic, small state machines, decoders, and simple control logic
Note: Exact I/O count and packaging can vary slightly by device variant; the -15 indicates a slower speed grade in this family.

Package

Plastic DIP (PDIP) package, 24-pin.

Pinout

- Pin count: 28 pins (28-pin package, e.g., DIP28/PLCC28).
- Function: A GAL16V8B-like programmable logic device (PAL/PLD) with 16 macrocells and 8 inputs, used to implement user-defined combinational logic (reprogrammable logic block).

Manufacturer

- Manufacturer: Actel Corporation (now part of Microchip Technology).
- What kind of company: A semiconductor company that designs and sells programmable logic devices, notably antifuse-based FPGAs and related PLDs.
