SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
Function
Apply voltage of 2.5 V to 5.5 V to V
CC
, and 0 V to V
SS
.
(Extended operating temperature version : 3.0 V to 5.5 V)
Reset input pin for active “L”
Input and output pins for the main clock generating circuit.
Feedback resistor is built in between X
IN
pin and X
OUT
pin.
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.
This clock is used as the oscillating source of system clock.
