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 Microprocessor Family, the 82C85 can also be used for general system

clock control.

For static system designs, separate signals are provided on

the 82C85 for stop (S0, S1, S2/STOP) and start (START)

control of the crystal oscillator and system clocks. A single

control line (SLO/FST) determines 82C85 fast (crystal/EFI

frequency divided by 3) or slow (crystal/EFI frequency

divided by 768) mode operation. Automatic maximum

mode 80C86 and 80C88 software HALT instruction decode

logic in the 82C85 enables software-based clock control.

Restart logic insures valid clock start-up and complete synchronization of system clocks.

The 82C85 is manufactured using the Intersil advanced

Scaled SAJI IV CMOS process. In addition to clock control

circuitry, the 82C85 also contains a crystal controlled

oscillator (up to 25MHz), clock generation logic, complete

“Ready” synchronization and reset logic. This permits the

designer to tailor the system power-performance product to

provide optimum performance at low power levels
