m PD784020, 784021
16/8-BIT SINGLE-CHIP MICROCOMPUTER
The mPD784021 is a product of the mPD784026 sub-series in the 78K/IV series. It contains various peripheral hardware such as RAM, I/O ports, 8-bit resolution A/D and D/A converters, timers, serial interface, and interrupt functions, as well as a high-speed, high-performance CPU. The mPD784021 is a ROM-less product of the mPD784025 or mPD784026. The mPD784020 differs from the mPD784021 only in its RAM size: 512 bytes are allocated for the mPD784020, while 2048 bytes are allocated for the mPD784021. For specific functions and other detailed information, consult the following user's manual.
