DESCRIPTION
The 38D5 Group is the 8-bit microcomputer based on the 740
Family core technology.
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.
