Advance Inforlll.ation 1.5 AND 2.0 MHz COMPONENTS FOR THE M6800 MICROCOMPUTER SYSTEM The eight devices described in this data sheet extend the operating frequency of the M6800 Microcomputer Family. The block diagrams and device operation are the same as for the basic M6800-series components. • Fully Hardware and Software Compatible with the M6800 Family • Power Dissipation Approximately 20% Lower Than on Standard MC6800 Series • Clock Specification Improved for Reduced Complexity 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. 1.5 MHz 2.
