DESCRIPTION
The 3822 group (A version) is the 8-bit microcomputer based on
the 740 family core technology.
The 3822 group (A version) has the LCD drive control circuit, an 8-
channel A-D converter, and a serial I/O as additional functions.
The various microcomputers in the 3822 group (A version) include
variations of internal memory size and packaging. For details, re-
fer to the section on part numbering.
