MOS INTEGRATED CIRCUIT
µPD7566A, 7566A(A)
4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The µPD7566A is a product of the µPD7554, 7564 sub-series which is a low-end, low-cost version of the
µPD7500 series microcomputers. This 4-bit single-chip microcomputer has fewer ports than the other products
in the µPD7500 series, in order to reduce the package size, and is especially ideal for temperature control
applications, as well as for application systems, such as air conditioners, microwave ovens, refrigerators, rice
cooker, washing machines, and cassette deck controllers. Some of the output pins for the microcomputer can
be used to directly drive triacs and LEDs.
In addition, various I/O circuits can be selected by mask options, so that the number of necessary external
circuits can be significantly reduced.
A detailed function description is provided in the following user's manual.
Be sure to read this manual when designing your system.
