Best Answer

The 8253 and 8254 are Programmable Interval Timers (PITs), which perform timing and counting functions.

They were primarily designed for the Intel 8080/8085-processors, but later used in x86-systems.

They (or an equivalent circuit embedded in a larger chip) are found in all IBM PC compatibles.
