The 38D5 Group is pin-compatible with the 38C5 Group. The 38D5 Group has an LCD drive control circuit, an A/D converter, a serial interface, and a ROM correction function as additional functions. The QzROM version and the flash memory version are available. The flash memory version does not have a selection function for the oscillation start mode. Only the on-chip oscillator starts oscillating. The various microcomputers include variations of memory size, and packaging. For details, refer to the section on part numbering.
