1. NC = NO CONNECT
2. THE EXPOSED PAD IS NOT CONNECTED INTERNALLY.
FOR INCREASED RELIABILITY OF THE SOLDER JOINTS
AND MAXIMUM THERMAL CAPABILITY, IT IS RECOMMENDED
THAT THE PAD BE SOLDERED TO THE GROUND PLANE.

ADD1
I2C Address Bit 1 for the AD7879-1. This pin can be tied high or low to determine an address
for the AD7879-1 (see Table 25).
7
GND
Ground. Ground reference point for all circuitry on the AD7879. All analog input signals and
any external reference signal should be referred to this voltage.

SDA
I2C Serial Data Input and Output for the AD7879-1.
12
PENIRQ/INT/DAV
Interrupt Output. This pin is asserted when the screen is touched (PENIRQ), when a measure-
ment exceeds the preprogrammed limits (INT), or when new data is available in the registers
(DAV). Active low, internal 50 k pull-up resistor.
13
AUX/VBAT/GPIO
This pin can be programmed as an auxiliary input to the ADC (AUX), as a battery measure-
ment input to the ADC (VBAT), or as a general-purpose digital input/output (GPIO).
14
N/A
CS
Chip Select for the SPI Serial Interface on the AD7879. Active low.
N/A
14
ADD0
I2C Address Bit 0 for the AD7879-1. This pin can be tied high or low to determine an address
for the AD7879-1 (see Table 25).
15
VCC/REF
Power Supply Input and ADC Reference.
16
X+
Touch Screen Input Channel.
EP
Exposed Pad. The exposed pad is not connected internally. For increased reliability of the
solder joints and maximum thermal capability, it is recommended that the pad be soldered
to the ground plane.
