Description
BUSY Output
This pin goes to low at CSN = “L”. BUSY signal is “H” only for the period between the falling
edge of 8
DCLK and the falling edge of 9
DCLK.
This pin is Hi-Z state at CSN= “H”
Serial Data Input
Inputs 8-bit control command data serially when CSN= “L”
AK4182A latches at the rising edge of DCLK. Must keep “L” while not issuing commands.
Chip Select Input
Enables writing data to the registers when CSN= “L”.
External Clock Input
Power Supply
Touch Screen X+ plate Voltage supply
X axis Measurement: Supplies the voltage to X+ position input
Y axis Measurement: This pin is used as the input for the A/D converter
Pen Pressure Measurement: This pin is the input for the A/D converter at Z1 measurement.
Temperature/VBAT/IN Measurement: OPEN state
Pen Waiting State: Pulled up by an internal resistor (typ.50K
).
Touch Screen Y+ plate Voltage supply
Y axis Measurement: Supplies the voltage to Y+ position input
X axis Measurement: This pin is used as the input for the A/D converter
Pen Pressure Measurement: Supplies the voltage.
Temperature/VBAT/IN Measurement: OPEN state
Pen Waiting State: OPEN state
Touch Screen X- plate Voltage supply
X axis Measurement: Supplies the voltage to X- position input
Y axis Measurement: OPEN state
Pen Pressure Measurement: Supplies the voltage.
Temperature/VBAT/IN Measurement: OPEN state
Touch Screen Y- plate Voltage supply
Y axis Measurement: Supplies the voltage to Y- position input
X axis Measurement: OPEN state
Pen Pressure Measurement: This pin is the input for the A/D converter at Z2 measurement.
Temperature/VBAT/IN Measurement: OPEN state
Pen Waiting State: connected to GND.
Ground
Analog Input for Battery Monitor
Auxiliary Analog Input
Voltage Reference Input/Output
2.5V reference voltage output at PD1 = “1”. Voltage reference input at PD1 = “0”.
Digital I/O Power Supply
Pen Interrupt Output
This pin is “L” during the pen down on pen interrupt enable state with CSN =“H” otherwise this
pin is “H”. This pin is “H” during pen interrupt disable state with the CSN = “H” regardless pen
touch. See
Power-down Control and
Pen Interrupt for the reference.
Serial A/D Data Output
Output A/D data serially at the falling edge of DCLK. MSB is output at the falling edge of
BUSY signal.
Output “L” at CSN= “L” during A/D data does not output.
This pin is Hi-Z state at CSN=”H”
