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.
This manual provides engineers with detailed information about the NEC 78KO/KE2 8‑bit microcontroller family, including the PD78F0531‑PD78F0537 variants. It describes the device architecture, pin assignments, internal modules, instruction set, and electrical characteristics, and offers guidance for system design and debugging.
The document also lists related development tools, programming hardware, and revision history, and includes safety and ESD protection recommendations for reliable use in production designs. This manual is written in Chinese.
