Pin Functions

PIN I/O A/D DESCRIPTION
NAME NO.
A0 14 Input Digital Address input bit 0
A1 13 Input Digital Address input bit 1
AUX 16 Input Analog Auxiliary channel input
GND 6 — — Ground
NC 7, 8, 9, 15 — — No connection
PENIRQ 10 Output Digital Data available interrupt output. A delayed (process delay) pen touch detect. Pin polarity with active low.
SCL 12 Input and Output Digital Serial clock. This pin is normally an input, but acts as an output when the device stretches the clock to delay a bus transfer.
SDA 11 Input and Output Digital Serial data I/O
VDD/REF 1 Input — Supply voltage and external reference input
X+ 2 Input Analog X+ channel input
X– 4 Input Analog X– channel input
Y+ 3 Input Analog Y+ channel input
Y– 5 Input Analog Y– channel input
