Function that detects uncontrolled looping and jumps to
a specified address
Voltage detection reset circuit
One 6-bit A/D converter
Two 8-bit A/D converters (PWM) (LC72321N and
LC72322N only)
One external interrupt (The external interrupt can be
selected to be one of the following: an external interrupt,
an internal timer interrupt, or the serial I/O circuit (in the
LC72321N).)
RAM data retention in hold mode
Sensing flip-flop for hot/cold start discrimination
PLL: 4.5 to 5.5 V
CPU: 3.5 to 5.5 V
RAM: 1.3 to 5.5 V
No. 5945-2/13
LC72321N, 72322N, 72323N

Pin Assignment
N-channel open-drain
output-only pins with 15-V
voltage handling capacity
PH2 and PH3 can be
switched to be used with the
D/A converter.*2
PH1 can be switched to be
used as the beep tone
function pin.*1
Input-only pins
The input voltage handling
capacity is 13 V
(maximum rating)
High voltage handling capacity
input ports (maximum ratings)
INT, RES, ADI
SNS, HOLD
→ 13 V
CMOS I/O
These pins can
be switched
between input
and output in
1-bit units.
CMOS I/O
These pins can be
switched between input
and output in 4-bit
units.
PE1, PE2, and PE3
can be switched to be
used by the SI/O
circuit.*1
CMOS output-only
pins
Option
CMOS output-only pins (for key outputs or
similar functions)
These are unbalanced CMOS outputs and
pairs of these pins may be shorted together.
Input-only pins (for key inputs or
similar functions)
The presence or absence of built-in pull-
down resistors can be selected.
Can be switch to function as
LCD segment outputs.
CMOS output-only pins
S1 through S28 can be
switched to function as
general-purpose CMOS
output ports.
(In the option
specifications)
Notes:*1. Only possible with the LC72321N
*2. Only possible with the LC72321N and LC72322N
