Description

The Intersil 82C85 Static CMOS Clock Controller/Generator provides complete control of static CMOS system operating modes and supports full speed, slow, stop-clock and stop-oscillator operation. While directly compatible with the Intersil 80C86 and 80C88 16-bit Static CMOS Microproces sor Family, the 82C85 can also be used for general system clock control.
