DESCRIPTION

The 38K2 group is the 8-bit microcomputer based on the 740 fam-

ily core technology.

The 38K2 group has the USB function, an 8-bit bus interface, a

Serial Interface, three 8-bit timers, and an 8-channel 10-bit A/D

converter, which are available for the PC peripheral I/O device.

The various microcomputers in the 38K2 group include variations

of internal memory size and packaging. For details, refer to the

section on part numbering.
