SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
Analog Comparator
An analog comparator circuit which is independent of peripheral cir-
cuits in the microcomputer is incorporated (
Note
).
An analog comparator outputs the result of comparison with an input
voltage of CMP
REF
pin which is specified as a reference voltage and
an input voltage of CMP
IN
pin to CMP
OUT
pin. The result is "1" when
the input voltage to port CMP
IN
is higher than the voltage applied to
port CMP
REF
and "0" when the voltage is lower.
Because the analog comparator consists of an analog MOS circuit,
set the input voltage to the CMP
IN
pin and the CMP
REF
pin within the
following range :
V
SS
+1.2 V to CMPV
CC
–0.5V
I
Note
The analog comparator circuit is separated from the MCU internal
peripheral circuit in the microcomputer. Accordingly, even if the mi-
crocomputer runs away, the analog comparator is still in operation.
For this reason, the analog comparator can be used for safety circuit
design.
