DESCRIPTION/FEATURES/APPLICATIONS/PIN CONFIGURATION
DESCRIPTION
The 3800 group is the 8-bit microcomputer based on the 740 fam-
ily core technology.
The 3800 group is designed for office automation equipment,
household appliances and include four timers, serial I/O function.
The various microcomputers in the 3800 group include variations
of internal memory size and packaging. For details, refer to the
section on part numbering.
For details on availability of microcomputers in the 3800 group, re-
fer to the section on group expansion.
