EF68B40P datasheet

Description :

The EF6840 is a programmable subsystem component of the 6800 family designed to provide variable system time intevals. The EF6840 has three 16-bit binary counters, three corresponding control registers and a status register. These counters are under software control and may be used to cause system interrupts and / or generate output signals.


1. Operates from a single 5 V power supply
2. Single system clock required ( Enable )
3. Fully TTL compatible
4. Programmable interrupt (IRQ) output to MPU
5. Readable down counter indicates conunts to go to time-out
6. Three maskable outputs
