Description
I
Control Data Chip Select
When read/write Touch Screen/Audio Control Data, set CS pin to “H”.
Read/Write operation requires 16 CCLK cycles. CS pin must be set to “L”
once per one Read/Write operation.
Audio/Touch Screen Data Control Clock Input
Clock signal used for Touch Screen/Audio control I/F.
Touch Screen/Audio Control Data Input
Control data is input to CDTI pin. The device latches data at the rising edge
of CCLK.
Touch Screen/Audio Control Data Output
Control data is output through CDTO pin. The device outputs data at the
falling edge of CCLK.

Touch Screen Reference Voltage Input
The TPVREFIN voltage is referenced as full scale of Touch Screen A/D
converter(TSADC)
This pin should be connected to 4.7uF and 0.1uF capacitors. Note that
maximum voltage is VA.
Battery level check Input_1
Note that maximum voltage is VA.
Battery level check Input_2
Note that maximum voltage is VA.
Touch Screen X_ TOP plate Voltage supply
Measurement of the position on X axis: This pin supplies the voltage to the
top side of the touch screen(normal mode -> VA, reverse mode -> AGND)
Measurement of the position on Y axis: The Input to Touch Screen A/D
converter(TSADC)
Powerdown Mode : OPEN
Pen Waiting Mode: OPEN
Touch Screen X_ BOTTOM plate Voltage supply
Measurement of the position on X axis: This pin supplies the voltage to the
bottom side of the touch screen(normal mode -> AGND, reverse mode ->
VA)
Measurement of the position on Y axis: OPEN
Powerdown Mode : OPEN
Pen Waiting Mode: This pin is connected to AGND through the resister.
Touch Screen Y_ TOP plate Voltage supply
Measurement of the position on Y axis: This pin supplies the voltage to the
top side of the touch screen(normal mode -> VA, reverse mode -> AGND)
Measurement of the position on X axis: The Input to Touch Screen A/D
converter(TSADC)
Powerdown Mode : OPEN
Pen Waiting Mode: OPEN
Touch Screen Y_ BOTTOM plate Voltage supply
Measurement of the position on Y axis: This pin supplies the voltage to the
bottom side of the touch screen(normal mode -> AGND, reverse mode ->
VA)
Measurement of the position on X axis: OPEN
Powerdown Mode : OPEN
Pen Waiting Mode: Supplies VA.
