0 TWO-PHASE MICROPROCESSOR CLOCK The Fujitsu MB 8867 is an advanced Microprocessor Clock Generator/Driver LSI manufactured with Fujitsu's bipolar TTL process.
The circuit generates non-overlapping two-phase clock signals for the Fujitsu MB L 6800 microprocessor unit or similiar single +5 volt MPU's.
Additionally, two·phase TTL clock signals synchronized with the MPU clock are provided, as well as an MPU data strobe, reset/clock controls for the memory interrupt, and an automatic power·up reset.
With the MB 8867, the entire MPU timing ·system can be designed with one chip and a minimum of external components.
A built·in oscillator permits external timing control by a ·crystal; or RC network timing can .
be utilised for less critical applications.
In th~ former; the internal frequency divider is rate selectable, so that the output frequency is either 1/4 or 1/16 of the ...
