3819 Group
SINGLE-CHIP 8-BIT MICROCOMPUTER
DESCRIPTION
The 3819 group is a 8-bit microcomputer based on the 740 family
core technology.
The 3819 group has a flourescent display automatic display circuit
and an 16-channel 8-bit A-D converter as additional functions.
The various microcomputers in the 3819 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 3819 group, re-
fer to the section on group expansion.
