1.5 AND 2.0 MHz PONENTS FOR THE M6800 MICROPUTER SYSTEM
The eight devices described in this data sheet extend the operating frequency of the M6800 Microputer Family. The block diagrams and device operation are the same as for the basic M6800-series ponents.
- Fully Hardware and Software patible with the M6800 Family
- Power Dissipation Approximately 20% Lower Than on Standard MC6800 Series
- Clock Specification Improved for Reduced plexity of Clock Generator/Driver Circuitry
- The MC6821 and its higher-frequency versions provide drive capability of two TTL loads on all A- and B-side buffers, improving the drive capability of the MC6820.
