DESCRIPTION
The 38B5 group is the 8-bit microcomputer based on the 740 family
core technology.
The 38B5 group has six 8-bit timers, a 16-bit timer, a fluorescent
display automatic display circuit, 12-channel 10-bit A-D converter, a
serial I/O with automatic transfer function, which are available for
controlling musical instruments and household appliances.
The 38B5 group has variations of internal memory size and packag-
ing. For details, refer to the section on part numbering.
For details on availability of microcomputers in the 38B5 group, refer
to the section on group expansion.
