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.

10

C1

GPIO, Column 1 in the Keypad Matrix.

11

C2

GPIO, Column 2 in the Keypad Matrix.

12

C3

15

C6

GPIO, Column 6 in the Keypad Matrix.

16

C7

GPIO, Column 7 in the Keypad Matrix.

17

C8

GPIO, Column 8 in the Keypad Matrix.

18

C9

GPIO, Column 9 in the Keypad Matrix.

19

GND

Ground.

20

RST

Hardware Reset (Active Low). This pin resets the device to the power default conditions. The reset pin must

be driven low for a minimum of 50 μs to be valid and to prevent false resets due to ESD glitches or noise in

the system. If not used, RST must be tied high with a pull-up resistor.

21

Supply Voltage, 1.7 V to 3.6 V.

22

SDA

23

SCL

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.
