MITSUBISHI MICROCOMPUTERS
38K0 Group
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
DESCRIPTION
LED direct drive port ................................................................... 4
Clock generating circuit
•
•
The 38K0 group is the 8-bit microcomputer based on the 740 fam-
ily core technology.
(connect to external ceramic resonator or quartz-crystal oscillator)
Power source voltage
The 38K0 group has the USB function, an 8-bit bus interface, a
Serial I/O, three 8-bit timers, and an 8-channel 10-bit A-D con-
verter, which are available for the PC peripheral I/O device.
The various microcomputers in the 38K0 group include variations
of internal memory size and packaging. For details, refer to the
section on part numbering.
