Signal description

A1

I2C_RST

Digital input

slave. Connect to GND via 47 kΩ resistor.

A2

RSVD4

Reserved

Connect to ground

A3

INT

Digital input/output

(I/O)

Interrupt output, defaults to opendrain output

(tristate), 47 kΩ pullup resistor to IOVDD required

A4

IOVDD

Power

1.8 V, 2.8 V or 3.3 V supply for digital core and

I/O supply

A5

LPn

Digital input

Comms enable. Drive this pin to logic 0 to

comms in LP mode. Typically used when it is

systems. A 47 kΩ pullup resistor to IOVDD is

required.

A6

RSVD1

Reserved

Connect to ground

A7

RSVD2

Reserved

Connect to ground

B1

AVDD

Power

2.8 V or 3.3 V analog and VCSEL supply

B4

THERMALPAD

Ground

Connect to a ground plane to allow good thermal

conduction

B7

AVDD

Power

2.8 V or 3.3 V analog and VCSEL supply

C1

GND

Ground

Ground

C2

RSVD6

Reserved

General purpose I/O, defaults to opendrain

output (tristate), 47 kΩ pullup resistor to IOVDD

required

C3

SDA

Digital I/O

Data (bidirectional), 2.2 kΩ pullup resistor to

IOVDD required

C4

SCL

Digital input

Clock (input), 2.2 kΩ pullup resistor to IOVDD

required

C5

RSVD5

Reserved

Do not connect

C6

RSVD3

Reserved

Connect to ground

C7

GND

Ground

Ground

Note:

The THERMALPAD pin has to be connected to ground (for more information refer to AN5853).

Note:

All digital signals must be driven to the IOVDD level.

Note:

Toggling the I2C_RST pin resets the sensor I2C communication only. It does not reset the sensor itself. To reset

the sensor refer to the sensor reset management procedure (UM3038).
