3802 Group
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
DESCRIPTION
The 3802 group is the 8-bit microcomputer based on the 740 fam-
ily core technology.
The 3802 group is designed for controlling systems that require
analog signal processing and include two serial I/O functions, A-D
converters, and D-A converters.
The various microcomputers in the 3802 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 3802 group, re-
fer to the section on group expansion.

PIN DESCRIPTION
Pin
VCC, VSS
Name
Power source
Function
• Apply voltage of 3.0 V–5.5 V to VCC, and 0 V to VSS.
(Extended operating temperature version : 4.0 V to 5.5 V)
Function except a port function
CNVSS
CNVSS
• This pin controls the operation mode of the chip.
• Normally connected to VSS.
• If this pin is connected to VCC, the internal ROM is inhibited and external memory is accessed.
VREF
Analog reference • Reference voltage input pin for A-D and D-A converters
voltage
AVSS
Analog power
source
• GND input pin for A-D and D-A converters
• Connect to VSS.
RESET
Reset input
• Reset input pin for active “L”
XIN
XOUT
Clock input
Clock output
• Input and output signals for the clock generating circuit.
• Connect a ceramic resonator or quartz-crystal oscillator between the XIN and XOUT pins to set the
oscillation frequency.
• If an external clock is used, connect the clock source to the XIN pin and leave the XOUT pin open.
• The clock is used as the oscillating source of system clock.
