NAME

GPIO1

Digital I/O

Digital core I/O

and control pins

Hi-Z

General purpose digital I/O 1. Float pin if it is configured as a push-pull

output in the application. Ground pin with a 1-MΩ resistor when unused in

the application.

No Ball

Blank

Ground and no

connect pins

—

Unpopulated ball for A1 marker and unpopulated inner ring.

I2C_SDA1

Digital I/O

Digital core I/O

and control pins

Digital input

I2C port 1 serial data. Open-drain output. Tie pin to LDO_3V3 or VDDIO

(depending on configuration) through a 10-kΩ resistance when used or

unused.

D10

GPIO2

Digital I/O

Digital core I/O

and control pins

Hi-Z

General purpose digital I/O 2. Float pin if it is configured as a push-pull

output in the application. Ground pin with a 1-MΩ resistor when unused in

the application.

D11

PP_5V0

Power

High-current

power pins

—

5-V supply for VBUS. Bypass with capacitance CPP_5V0 to GND. Tie pin

to GND when unused.

I2C_SCL1

Digital I/O

Digital core I/O

and control pins

Digital input

I2C port 1 serial clock. Open-drain output. Tie pin to LDO_3V3 or VDDIO

(depending on configuration) through a 10-kΩ resistance when used or

unused.

No Ball

Blank

Ground and no

connect pins

—

Unpopulated ball for A1 marker and unpopulated inner ring.

DEBUG_CTL2

(GPIO17, I2C ADDR

B5)

Digital I/O

Digital core I/O

and control pins

Hi-Z

General purpose digital I/O 17. At power-up, pin state is sensed to

determine bit 5 of the I2C address.

HRESET

Digital I/O

Digital core I/O

and control pins

Hi-Z

Active high hardware reset input. Will re-load settings from external flash

memory. Ground pin when HRESET functionality is not used.

GPIO7

Digital I/O

Digital core I/O

and control pins

Hi-Z

General purpose digital I/O 7. Float pin if it is configured as a push-pull

output in the application. Ground pin with a 1-MΩ resistor when unused in

the application.

GND

Ground

Ground and no

connect pins

—

Ground. Connect all balls to ground plane.

No Ball

Blank

Ground and no

connect pins

—

Unpopulated ball for A1 marker and unpopulated inner ring.

LDO_BMC

Power

Low-current

power pins

—

Output of the USB-PD BMC transceiver output level LDO. Bypass with

capacitance CLDO_BMC to GND.

E10

GPIO5

(HPD RX)

Digital I/O

Digital core I/O

and control pins

Hi-Z

General purpose digital I/O 5. Can be configured as Hot Plug Detect (HPD)

RX when DisplayPort mode supported. Must be tied high or low through a

1-kΩ pullup or pulldown resistor when used as a configuration input.

Ground pin with a 1-MΩ resistor when unused in the application.

E11

MRESET

(GPIO11)

Digital I/O

Digital core I/O

and control pins

Hi-Z

General purpose digital I/O 11. Forces RESETZ to assert. By default, this

pin asserts RESETZ when pulled high. The pin can be programmed to

assert RESETZ when pulled low. Ground pin with a 1MΩ resistor when

unused in the application.

UART_TX

Digital

output

Port multiplexer

pins

UART_RX

UART serial transmit data. Connect pin to another TPS65982 UART_TX to

share firmware. Connect UART_RX to UART_TX when not connected to

another TPS65982.

No Ball

Blank

Ground and no

connect pins

—

(GPIO16, I2C ADDR

B4)

Digital I/O

Digital core I/O

and control pins

Hi-Z

General purpose digital I/O 16. At power-up, pin state is sensed to

determine bit 4 of the I2C address.

GND

Ground

Ground and no

connect pins

—

Ground. Connect all balls to ground plane.

No Ball

Blank

Ground and no

connect pins
