Intersil MD82C85B

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. 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.

DESCRIPTION

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. 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.
