Block diagram of Intel 8253 The timer has three counters, numbered 0 to 2. [7] Each channel can be programmed to operate in one of six modes. Once programmed, the channels operate independently. [1] Each counter has two input pins - "CLK" ( clock input) and "GATE" - and one pin, "OUT", for data output.
8253 Programmable Timer
The 82C54 is pin compatible with the HMOS 8254, and is a superset of the 8253. Six programmable timer modes allow the 82C54 / 8253 to be used as an event counter, elapsed time indicator, programmable one-shot, and in many other applications. 4.4.1 Block diagram. The timer has three independent, programmable counters and they are all identical. The

Intel 8254 is a programmable interval timer designed by intel is a programmable external timer device built with an aim to resolve the time control issues that occur in between various processes occurring within the microprocessor. In order to communicate with the processor, it has a total of 8 data lines.
Block diagram of 8253
The Intel 8253 and 8254 are Programmable Interval Timers (PTIs) designed for microprocessors to perform timing and counting functions using three 16-bit registers. Each counter has 2 input pins, i.e. Clock & Gate, and 1 pin for "OUT" output. To operate a counter, a 16-bit count is loaded in its register.
