概述

Description

ATF16V8B-10JU is a flash-based CPLD from Atmel (now Microchip). It provides 16 macrocells with programmable interconnect to implement small-scale digital logic (glue logic, simple state machines, and peripheral interfaces). The configuration is stored on-chip in flash, so the device is non-volatile and can be reprogrammed in-system without an external PROM. The “-10” is its speed grade, indicating faster timing, and “-JU” denotes the specific package variant. Typical use is when a compact, low-cost programmable logic device is needed to glue together a microcontroller and peripherals or decoders. Programming is done with Microchip/Atmel tools and can often be performed in-system via the appropriate programmer. Benefits include quick startup and reprogrammability; limitation is its modest capacity compared with larger CPLDs or FPGAs.

Features

Here are concise features of ATF16V8B-10JU:
- 16 macrocells (CPLD) with embedded D-flip-flops
- 4-input logic per macrocell and programmable interconnect for flexible routing
- 8 user I/O pins with 3-state buffers and configurable input/output options
- Non-volatile configuration memory with in-system programming
- JTAG boundary-scan for programming, testing, and diagnostics
- Speed grade: -10 (typical around 10 ns; depends on design)
- 5V operation with compatible logic levels
- Low power operation and suitable for compact, glue-logic designs
- Small package options (JU family variants)
Note: exact I/O count and package variants may vary by specific device/lot.

Package

Plastic DIP, 20-pin (DIP-20) package.

Pinout

- Pin count: 28 pins (DIP/28-pin variants).
- Function: ATF16V8B is a PAL/PLD (programmable logic device) in the PAL16V8 family, providing 16 input lines and 8 programmable output lines for implementing combinational logic. It’s a 5V TTL-compatible PAL device.

Manufacturer

- Manufacturer: Atmel Corporation (now part of Microchip Technology).
- What kind of company: A semiconductor company that designs and manufactures integrated circuits (notably microcontrollers, memory, and related ICs).

Application

ATF16V8B-10JU application areas:
- Glue logic and simple control logic in microcontroller-based systems
- Address/Peripheral decoding and interfacing
- Finite state machines and sequencing logic
- Timing/decoding circuits (counters, multiplexers)
- Rapid prototyping or replacement of TTL logic in low- to medium-volume designs

Equivalent

Common cross-references for ATF16V8B-10JU (28-pin) are:
- Lattice GAL16V8B family (e.g., GAL16V8B-20, -25, -30)
- AMD PAL16V8 / PAL16L8 family (pin-compatible)
Also consider other GAL/PAL 16V8-compatible devices. Always verify package (DIP28/SOIC-28) and timing/speed grades when substituting.
