D8254 - Programmable Interval Timer

D8254 - Programmable Interval Timer Description:

Overview

The D8254 is a programmable interval timer/counter, binary compatible with industry standard 82C54. The D8254 solves one of the most common problems in any micro-computer system, the generation of accurate time delays under software control. The D8254 can be used as a:
- Real time clock
- Even counter
- Digital one-shot
- Programmable rate generator
- Square wave generator
- Binary rate multiplier
- Complex waveform generator
- Complex motor controller

D8254 includes fully automated testbench with complete set of tests allowing easy package validation at each stage of SoC design flow.
D8254 is a technology independent design that can be implemented in a variety of process technologies.
