Overview

The ATF22V10C-10JU is a high-performance CMOS Electrically Erasable Programmable Logic Device (EE PLD) featuring 10 macrocells and 5V operation. It provides a flexible solution for replacing discrete logic in legacy and modern systems, offering 10 ns propagation delays and 2,000V ESD protection. This device is backward-compatible with the Atmel ATF22V10B and AT22V10 series, making it a reliable drop-in upgrade for existing 22V10 designs.

Why Choose This Part

The ATF22V10C-10JU features a high-reliability CMOS process with 20-year data retention and 200mA latch-up immunity. It includes a low-power standby mode (650uA) and is PCI-compliant, making it suitable for industrial environments requiring high noise immunity and 5V I/O compatibility. The 10 ns speed grade ensures it can keep pace with fast system clocks and asynchronous control signals.

Applications

Glue Logic Replacement
Consolidates multiple 74-series logic gates and flip-flops into a single 28-PLCC package to save PCB real estate.
DMA Control
Implements custom Direct Memory Access arbitration and control logic for 5V embedded processors.
State Machine Implementation
Ideal for building synchronous or asynchronous state machines with up to 10 registers.
Graphics Processing Support
Handles timing and interface logic for legacy video displays and graphics controllers.

Getting Started

To program this PLD, engineers typically use CUPL or ABEL hardware description languages to define logic equations. The resulting JEDEC file is uploaded via a universal device programmer that supports 28-PLCC adapters. Ensure your system provides a stable 4.5V to 5.5V supply for reliable operation.
