Function description
Option
- Power terminal (-)
- •Power terminal(+) (Ag battery version)
Battery version
•Voltage supply to LCD driver (Li battery version, EXTV
Ag/Li/EXTV
version) (C is connected between VDD1 and VSS.)
•Voltage supply to logic unit (Ag battery version,
Back up flag off at Li battery version.)
- •Power terminal(+) (Li battery version, EXTV version)
Battery version
•Voltage supply to LCD driver (Ag battery version)
Ag/Li/EXTV
(C is connected between VDD2 and VSS.)
•Voltage supply to logic unit (EXTV version, Back up flag
is ON at Li battery version.)
- •Power terminal(+)
•For Li battery version, a capacitor must be connected
across BAK and VSS to prevent logic unit from
malfunctioning.
- Capacitor connecting terminals for step-up
(doubler/tripler)
I •4-bit input port
•LSI reset by S1-S4
•Input for HALT release
