Power terminal(-)
Power terminal(+) (Ag battery version)
Voltage supply to LCD driver (Li battery & EXTV ver.)
(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 & EXTV version)
Voltage supply to LCD driver (Ag battery version)
(C is connected between VDD2 and VSS.)
Voltage supply to logic unit (EXTV version,
Back up flag 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/step-down.
4-bit input port
Input for HALT release
LSI system is reset by applying VDD* to S1 to S4
simultaneously. (Mask option)
*Ag version : VDD1
Li/EXTV
VDD2
Programmable pull-down resistor
”L”-level hold Tr. (Mask option)
2-bit input port
Input for HALT release
Programmable pull-down resistor
”L”-level hold Tr.
Output terminal
Selectable general output or buzzer output by mask
option
(1) As using general output port
The output level is controlled by executing the SLGT
and RLGT instructions.
(2) As using buzzer output
Melody signal or 9 kinds of modulated signal is
controlled by executing the SAS or TMEL instructions.*
(Possible to output non-modulated signal)
Possible to output 3 octave melody signal.
LCD output terminals for segment
Possible to use output port for SEG13 to SEG25
(Pad No.12 to 24) by mask option.
SEG13 can be used as COM4 output by mask option.
