MOS INTEGRATED CIRCUIT

µPD7564A, 7564A(A)

4-BIT SINGLE-CHIP MICROCOMPUTER

DESCRIPTION

The µPD7564A is a 4-bit single-chip microcomputer with a small number of ports in a small package, which is

of low-order models, µPD7554 and 7564 sub-series in the µPD7500 series. With an on-chip serial interface, it per-

forms efficient dispersion processing of a system as a sub-CPU for the 75X series or 78k series.

The µPD7564A has outputs to directly drive a triac and LEDs and allows selection among many types of input/

output circuits using their respective mask options, sharply reducing the number of external circuits required.

Details of functions are described in the User’s Manual shown below. Be sure to read in design.
