82C85 March 1997 CMOS Static Clock Controller/Generator 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.

82C89 March 1997 CMOS Bus Arbiter Description The Intersil 82C89 Bus Arbiter is manufactured using a selfaligned silicon gate CMOS process (Scaled SAJI IV). This circuit, along with the 82C88 bus controller, provides full bus arbitration and control for multi-processor systems. The 82C89 is typically used in medium to large 80C86 or 80C88 systems where access to the bus by several processors must be coordinated. The 82C89 also provides high output current and capacitive drive to eliminate the n.

CMOS Static Clock Controller/Generator

82C85 March 1997 CMOS Static Clock Controller/Generator 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. Features • Generates the System Clock For CMOS or NMOS Microprocessors and Peripherals • Complete Control Over System Operation for Very L.
