Description
1
R7
GPIO, Row 7 in the Keypad Matrix.
2
R6
GPIO, Row 6 in the Keypad Matrix.
3
R5
GPIO, Row 5 in the Keypad Matrix.
4
R4
GPIO, Row 4 in the Keypad Matrix.
5
R3
GPIO, Row 3 in the Keypad Matrix.
6
R2
GPIO, Row 2 in the Keypad Matrix.
7
R1
GPIO, Row 1 in the Keypad Matrix.
8
R0
GPIO, Row 0 in the Keypad Matrix.
9
C0
GPIO, Column 0 in the Keypad Matrix.
10
C1
GPIO, Column 1 in the Keypad Matrix.
11
C2
GPIO, Column 2 in the Keypad Matrix.
12
C3
GPIO, Column 3 in the Keypad Matrix.
13
C4
GPIO, Column 4 in the Keypad Matrix.
14
C5
GPIO, Column 5 in the Keypad Matrix.
15
C6
GPIO, Column 6 in the Keypad Matrix.
16
C7
GPIO, Column 7 in the Keypad Matrix.
17
CMP_IN1/C8
GPIO, Column 8 in the Keypad Matrix; Comparator Input for Photosensor 1.
18
CMP_IN2/C9
GPIO, Column 9 in the Keypad Matrix; Comparator Input for Photosensor 2.
19
GND
Ground.
20
RST
Hardware Reset (Active Low). This bit resets the device to the power default conditions. The reset pin must be
driven for a minimum of 50 μs to be valid and to prevent falsing due to ESD glitches or noise in the system. If
not used, RST must be tied high with a pull-up.
21
VCC
VCC = 1.7 V to 3.3 V.
22
SDA
I2C Serial Data (Open Drain Requires External Pull-up).
23
SCL
I2C Clock.
24
INT
Processor Interrupt, Active Low, Open Drain. This pin can be pulled up to 2.7 V or 1.8 V for selection flexibility in
the processor GPIO supply group.
EP
EPAD
Exposed Pad. The exposed pad must be connected to ground.
