UPD7564A(A)的产品描述：
The UPD7564A 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 UPD7564A 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.
