Overview
The D8254 is a programmable interval timer/counter, binary compatible with the 82C54 industry standard. Since DCD's core value is innovation, this unique IP Core 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: - Real time clock - Even counter - Digital one-shot - Programmable rate generator - Square wave generator - Binary rate multiplier - Complex waveform generator - Complex motor controller - Interrupt on terminal count The D8254 includes fully automated test bench with complete set of tests , which allows an easy package validation at each stage of SoC design flow. Our proprietary core is a technology independent design that can be implemented in a variety of process technologies.
