SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
MITSUBISHI MICROCOMPUTERS
38K0 Group
DESCRIPTION
The 38K0 group is the 8-bit microcomputer based on the 740 fam-
ily core technology.
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.

CC
, and 0 V to V
SS
.
Power source pin for ports P1, P3, P4 and analog circuit. Connect this pin to V
CC
.
This pin controls the operation mode of the chip. Connect this pin to V
SS
. In the flash memory
mode, this pin becoems V
PP
power source input pin.
This pin controls the operation mode of the chip. Connect this pin to V
SS
.
Reference voltage input pin for A-D converter.
Power source pin for analog circuit.
Connect the DV
CC
and PV
CC
pins to V
CC
, and the PV
SS
pin to V
SS
.
Reset input pin for active "L"
Input and output pins for the main clock generating circuit.
Connect a ceramic resonator or a quartz-crystal oscillator between the X
IN
and X
OUT
pins to set
the oscillation frequency.
If an external clock is used, connect the clock source to the X
IN
pin and leave the X
OUT
pin open.
Power source pin for USB port circuit.
In Vcc = 4.00 to 5.25 V use the built-in USB reference voltage circuit. In Vcc = 3.00 to 4.00 V apply
3.3 V power supply from the external because use of the built-in USB reference voltage circuit is
prohibited in this voltage range. In Vcc = 3.00 to 3.60 V connect this pin to V
CC
.
