DEF Group
I – HOST Serial data transfer clock. Serial data is transferred synchronizing with this clock.
SCLK is used as the master clock for TC35143AF. The specification of SCLK is 9.216 MHz,
with duty ratio 50%. Connect to the clock output of SIB master chip.
I HOST This signal provides synchronization for serial data frames. 72kHz clock. 1 frame consists
of 128 bits of serial data. Connect to the synchronizing signal output of SIB master chip.
I HOST Serial input data terminal. Serial data input through the SDIN terminal is latched inside at
the falling edge of SCLK. Connect to the data output of SIB master chip.
O HZ HOST Serial output data terminal. Serial data output through SDOUT terminal is output, synchro-
nizing with the rising edge of SCLK. Connect to the data input of SIB masterchip.
O L HOST Interrupt output terminal. Interrupt factors output from the control resistor to this terminal
are set. The signal level at the time of interrupt is active high.
I – HOST System reset. This signal is active low.
HZ(IN) TSC Interface terminal for touch screen X plate. Open when not in use.
HZ(IN) TSC Interface terminal for touch screen X place. Open when not in use.
HZ(IN) TSC Interface terminal for touch screen Y plate. Open when not in use.
HZ(IN) TSC Interface terminal for touch screen Y plate. Open when not in use.
I – ADC ADC input
I – ADC ADC input
I – ADC ADC input
I – ADC ADC input
I – ADC Synchronizing clock input terminal when putting 10-bit ADC in the external clock synchro-
nizing mode. ADC starts conversion synchronizing with the edge of ADSYNC.Pull down
when not in use.
I – TSC Terminal to which external resistance is connected, for adjusting detection sensitivity in
touch detection mode. Connect a resistance of more than 16kΩ between AVDD5.
O HZ TEL Positive polarity output terminal for telephone line CODEC
O HZ TEL Negative polarity output terminal for telephone line CODEC
I – TEL Positive polarity input terminal for telephone line CODEC. Open when not in use.
I – TEL Negative polarity input terminal for telephone line CODEC. Open when not in use.
O HZ VB Positive polarity output terminal 1 for sound CODEC. It is used for the handset speaker.
O HZ VB Negative polarity output terminal 1 for sound CODEC. It is used for the handset speaker.
