Pin name

Pin location

Pin function

V1V8

G5, G8

1.8V LDO output and supply rail for the digital core, the ADC and the analog circuitry.

Connect a 1 μF filtering capacitor between this pin and ground.

V5V0

F7, E6

5V LDO output and supply rail for the auxiliary circuitry. Connect a 4.7 μF filtering

capacitor between this pin and ground.

RSTB

Chip-reset input. If set low, the internal digital core is reset. This pin can also be used

by the host controller to control the power transfer process.

SCL

I2C bus, clock line input. A pull-up resistor to the supply rail of the host controller is

required to ensure correct digital levels. I2C bus, data line I/O. A pull-up resistor to the

supply rail of the host controller is required to ensure correct digital levels.

SDA

GPIO0

Programmable general-purpose I/Os: the function of these pins depends on the

configuration of the device.

GPIO1

GPIO2

GPIO3

GPIO4

GPIO5

GPIO7

INTB/GPIO6

Interrupt output (active low). Programmable open-drain output used to generate an

interrupt on specific events for the host controller.

C2,C6,C7,C8,

D1,D6,D7,D8,E8

Not connected pins , to be left floating.
