Description
OSCIN I Typical crystal(32.768KHz) is connected across
OSCOUT O OSCIN/OSCOUT for oscillation; R/C oscillation mode is also available.
S1~4
I Input ports with chattering eliminator option for CK10 (32ms), CK8 (8ms) &
M1~4
I CK6 (2ms).
P1~4
O Output ports.
IOA1~4 I/O Input/Output ports.
IOB1~4 I/O Input/Output ports.
INT
I External interrupt request control input pin.
RESET I System reset pin.
LIGHT O Output only for outputting the signal to drive the transistor for light.
ALARM O Output only for outputting the 4kHz/2kHz/1kHz modulation signal.
Also can be used to output the non-modulation signal.
VDD
(+)Power supply pin.
VDD1
* For Ag version, apply (+) side to VDD & VDD1 together.
VDD2
For other than Ag version, apply (+) side to VDD & VDD2 together.
VDD3
Power supply pin for LCD driver power supply.
VSS
(--)Power supply pin.
CUP1~2 O Pins for connecting the voltage step-up (step-down) capacitor.
COM1~3 O Output pins for LCD panel common plate.
SEG1~25 O Output pins for LCD panel segments.
