DATA SHEET MOS INTEGRATED CIRCUIT ELECTRON DEVICE µPD75238 4 BIT SINGLE-CHIP MICROCOMPUTER The µPD75238 is a single-chip microcomputer which contains a CPU capable of 1-, 4-, and 8-bit data processing, ROM, RAM, and I/O ports. In addition, it contains a fluorescent display tube (FIP;) controller/driver, A/D converter, clock timer, timer/pulse generator capable of 14-bit PWM output, serial interface, and vectored interrupt function. In comparison with the µ PD75217, the µPD75238 has larger ROM and RAM capacity and has been enhanced in such peripheral facilities as the display function of the FIP controller/driver, I/O ports, A/D converter, serial interface.
