ATF16V8B-15JC

ATF16V8B-15JC is a flash-based PLD (programmable logic device) from Atmel in the 16V8 family. It provides 16 macrocells in a PAL-like architecture, with each macrocell containing a D-type flip-flop and a programmable combinational network (usually built from an 8-input OR/AND/LUT style structure). It’s designed to replace several TTL gates or small state machines in a single chip.
Key points:
- -15 = speed grade (≈ 15 ns)
- JC = package code (24-pin variant in Atmel’s packaging)
- Reprogrammable in-system; configuration stored in on-chip flash
- Typical supply: about 4.5–5.5 V
- Use cases: glue logic, decoders, counters, simple state machines;GAL16V8-compatible
In short, a compact, reusable PLD for small logic blocks and simple sequential logic, with easy reprogramming.

Equivalent parts to ATF16V8B-15JC include:
- Lattice GAL16V8B-15 (same 16-macrocell EPLD, typically pin-compatible in common packages)
- AMD PALCE16V8 (16V8 family, similar pinout)
Note: exact packaging and speed grade must match; verify datasheets for full cross-compatibility.

ATF16V8B-15JC features (concise):
- Antifuse-based FPGA (one-time programmable, nonvolatile configuration)
- 16V8 architecture (simple, small programmable logic with 16 input terms and 8 macrocells)
- Speed grade: -15 (approximately 15 ns)
- 5V-compatible I/O with TTL/CMOS level compatibility
- Low-power CMOS design
- Small package (JC) suitable for compact designs
- Integrated programmable logic for combinational and simple sequential functions
Note: exact I/O count and packaging details vary by revision; refer to datasheet for precise specs.

- Pin count: 20 pins (PLCC‑20/DIP‑20 form factors; the "-JC" suffix denotes the 20‑lead PLCC package).
- Function: ATF16V8B is a high‑performance Electrically Programmable Logic Device (EPLD / GAL) in the 16V8 family — a 20‑pin PLD providing user‑programmable combinational and registered logic (typically implemented as up to 16 inputs and 8 outputs/macrocells), TTL‑compatible I/O, and selectable product terms. The “-15” speed grade indicates ~15 ns typical propagation; it is used to replace multiple standard TTL logic ICs with a single configurable device.

Manufacturer: Atmel (the ATF16V8B-15JC is an Atmel part). Atmel was acquired by Microchip Technology in 2016, and the product line is now under Microchip.
Type of company: Atmel was a semiconductor company that designed and manufactured integrated circuits—especially microcontrollers (AVR), programmable logic devices (PLDs/CPLDs like the ATF16V8B), memory and analog chips. Microchip, its acquirer, is a global semiconductor manufacturer providing embedded control and analog products.

ATF16V8B-15JC is a small antifuse FPGA (16V8 family) that is non-volatile and one-time programmable. Common applications include:
- Glue logic for microprocessors/microcontrollers
- Address decoding and peripheral interfacing
- Small state machines, counters and timers
- Sequencing and control logic
- Replacement for PAL/PLA in low-volume designs
- IO expansion and custom logic for embedded systems
- Pattern generation and basic digital signal control
- Rapid prototyping for automotive, consumer and industrial electronics
Note: its configuration is permanent once programmed.

The ATF16V8B-15JC is supplied in a 20-pin PLCC (J‑lead) package.
