Motorola - MC68B40P - IC, Timer.

The MC6840 is a programmable subsystem component of the M6800 Family designed to provide variable system time intervals. The MC6840 has three 16-bits binary counters, three corresponding control registers, and status register. These counters are under software control and may be used to cause system interrupts and or generate output signals.

Programmable timer module (PTM).

Package: 28 Dip.
