Description
Power Supply
Touch Screen X+ plate Voltage supply
X axis Measurement: Supplies the voltage
Y axis Measurement: This pin is used as the input for the A/D converter
Pen Pressure Measurement: This pin is the input to the A/D converter at Z1 measurement.
Temperature/VBAT/IN1/IN2 Measurement: OPEN state
Powerdown State: is pulled up by an internal resistor (typ.20k ohm).
Touch Screen Y+ plate Voltage supply
Y axis Measurement: Supplies the voltage
X axis Measurement: This pin is used as the input for the A/D converter
Pen Pressure Measurement: Supplies the voltage.
Temperature/VBAT/IN1/IN2 Measurement: OPEN state
Powerdown State: OPEN state.
Touch Screen X- plate Voltage supply
X axis Measurement: Supplies the voltage
Y axis Measurement: OPEN state
Pen Pressure Measurement: Supplies the voltage.
Temperature/VBAT/IN1/IN2 Measurement: OPEN state
Powerdown State: OPEN state
Touch Screen Y- plate Voltage supply
Y axis Measurement: Supplies the voltage
X axis Measurement: OPEN state
Pen Pressure Measurement: This pin is the input to the A/D converter at Z2 measurement.
Temperature/VBAT/IN1/IN2 Measurement: OPEN state
Powerdown State: connected to GND.
Ground
Analog Input for Battery Monitor
Auxiliary 1 Analog Input
Voltage Reference Input/Output
Outputs 2.5V
Auxiliary 2 Analog Input
Pen Interrupt Output
This pin should be pulled up via a 100k-ohm resistor.
Serial A/D Data Output
Outputs A/D data serially at the falling edge of DCLK. MSB is output at the falling edge of
BUSY signal.
DOUT is “L” at CSN=”L” except that A/D data is output.
This pin is Hi-Z state at CSN=”H”
BUSY Output
This pin goes to low at CSN = “L”. BUSY signal is “H” only for the period between the falling
edge of 8DCLK and the falling edge of 9DCLK.
This pin is Hi-Z state at CSN=”H”
Serial Data Input
Inputs 8-bit control command data serially when CSN=”L”
AK4180 latches at the rising edge of DCLK. Please keep “L” except when issuing commands.
Chip Select Input
Enables writing to the registers when CSN=”L”. CSN=”H” and DIN=”H” force the internal
registers to initial value, 00h. (Full Powerdown)
