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, 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. 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. FEATURES
