Function
Logical "High" input port (+5V ± 10%, +3V ± 10%)
0V (GND)
Logical "Low" for high voltage part
Bias supply voltage input to drive the LCD. Bias voltage divided
by the resistance is usually used as a supply voltage source
(refer to NOTE 2).
Display data output pin which corresponds to the respective latch
contents. One of V0, V12, V34 and V5 is selected as a display
driving voltage source according to the combination of the
latched data level and M signal (refer to NOTE 1).
Clock pulse input for the bi-directional shift register.
– In segment driver application mode, the data is shifted to 20 x
4-bit segment data shift
The clock pulse, which was input when the enable bit
(ELB/ERB) is in not active condition, is invalid.
– In common driver application mode, the data is shifted to 80-bit
common data bi-directional shift register by the CL1 clock.
Hence, this clock pin is not used (Open or connect this pin to
VDD).
Alternate signal input pin for LCD driving.
Normal frame inversion signal is input in to this pin.
– In segment driver application mode, this signal is used for
latching the shift register contents at the falling edge of this clock
pulse.
CL1 pulse "High" level initializes power-down function block.
– In common driver application mode, CL1 is used as a shifting
clock of common output data.
Control input pin to fix the driver output (SC1~SC80) to V0 level,
during "Low" value input. LCD becomes non-selected by V0 level
output from every output of segment drivers and every output of
common drivers.
When CS = "Low", S6B0086 is used as an 80-bit segment driver.
When CS = "High", S6B0086 is set to an 80-bit common driver
