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 testbench 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.
