This document describes the features and characteristics of the 78K0/KE2 series 8-bit single-chip microcontrollers, including the features of models such as μPD78F0531, μPD78F0531(A), μPD78F0531(A2), μPD78F0532, μPD78F0532(A), etc. This series of products have on-chip debugging function, but it is not recommended to use in large-scale production. The document also introduces precautions such as voltage waveform at input pins of CMOS devices, handling of unused input pins, ESD protection measures, state before initialization, and power switch order.
