Mnemonic

Description

SCLK

SPI Communication Clock. Tied low for I2C.

MOSI/SDA

Main Output, Subordinate Input (MOSI), or I2C Serial Data (SDA).

MISO/ASEL

Main Input, Subordinate Output (MISO), or I2C Address Select (ASEL).

CS/SCL

SPI Chip Select, Active Low (CS), or I2C Clock (SCL).

INT1

Interrupt 1 Output. INT1 also serves as an input for external clocking.

INT2

Interrupt 2 Output. INT2 also serves as an input for synchronized sampling.

GND

Ground. The GND pin must be grounded.

ADC_IN

ADC Input Pin. The ADC_IN pin can be left unconnected or can be connected to Pin 7 (GND) and/or Pin 11 (GND).

VREG_OUT1

Internally Regulated Voltage.

Supply Voltage.

GND

Ground. The GND pin must be grounded.

VDDIO

Supply Voltage for Digital Input and Output.

1 The VREG_OUT pin is used as an internal supply decoupling pin, and an external 0.2μF capacitor is also required.
