Programmable Interval Timer
ver 1.05
O V E R V I E W
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
K E Y F E AT U R E S
●
Three independent 16-bit counters
●
Six programmable Counter modes
○
Interrupt on terminal count
○
Hardware retriggerable One-Shot
○
Rate Generator
○
Square wave mode
○
Software triggered strobe
○
Hardware triggered strobe
●
Binary or BCD counting
●
Status Read Back Command
●
Simple interface allows easy connection
to microcontrollers
●
Fully synthesizable, static design with no
internal tri-states
