3806 Group
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
DESCRIPTION
The 3806 group is 8-bit microcomputer based on the 740 family
core technology.
The 3806 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 3806 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 3806 group, re-
fer to the section on group expansion.

• Apply voltage of 3.0 V to 5.5 V to V
CC
, and 0 V to V
SS
.
(Extended operating temperature version : 4.0 V to 5.5 V)
(High-speed version : 2.7 V to 5.5 V)
• This pin controls the operation mode of the chip.
• Normally connected to V
SS
.
• If this pin is connected to V
CC
, the internal ROM is inhibited and external memory is accessed.
• Reference voltage input pin for A-D and D-A converters
• GND input pin for A-D and D-A converters
• Connect to V
SS
.
• Reset input pin for active “L”
• Input and output signals for the internal clock generating circuit.
• Connect a ceramic resonator or 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.
• The clock is used as the oscillating source of system clock.

•
8 bit CMOS I/O port
I/O direction register allows each pin to be individually programmed as either input or output.
At reset this port is set to input mode.
In modes other than single-chip, these pins are used as address, data, and control bus I/O pins.
