BALL NUMBER

BALL NAME

CONNECTION REQUIREMENTS

B20

MCU_SAFETY_ERRORn

TRSTn

Each of these balls must be connected to VSS through separate

external pull resistors to ensure these balls are held to a valid logic

low level if a PCB signal trace is connected and not actively driven

by an attached device. The internal pull-down can be used to hold a

valid logic low level if no PCB signal trace is connected to the ball.

C17

EMU0

EMU1

MCU_RESETz

RESET_REQz

TCK

TDI

TMS

Each of these balls must be connected to the corresponding power

supply(1) through separate external pull resistors to ensure these

balls are held to a valid logic high level if a PCB signal trace

is connected and not actively driven by an attached device. The

internal pull-up can be used to hold a valid logic high level if no PCB

signal trace is connected to the ball.

B16

B15

I2C0_SCL

I2C0_SDA

Each of these balls must be connected to the corresponding power

supply(1) through separate external pull resistors to ensure these

balls are held to a valid logic high level.

VDDA_ADC

ADC0_AIN0

ADC0_AIN1

ADC0_AIN2

ADC0_AIN3

ADC0_AIN4

ADC0_AIN5

ADC0_AIN6

ADC0_AIN7

If the entire ADC0 is not used, each of these balls must be

connected directly to VSS.

ADC0_AIN0

ADC0_AIN1

ADC0_AIN2

ADC0_AIN3

ADC0_AIN4

ADC0_AIN5

ADC0_AIN6

ADC0_AIN7

Any unused ADC0_AIN[7:0] ball must be pulled to VSS through a

resistor or connected directly to VSS when VDDA_ADC is connected

to a power source.

K15

J17

VDDA_3P3_SDIO

CAP_VDDSHV_MMC1

If SDIO_LDO is not used to power VDDSHV5, each of these balls

must be connected directly to VSS.

V16

U15

U16

VDDA_0P85_USB0

VDDA_1P8_USB0

VDDA_3P3_USB0

If USB0 is not used, each of these balls must be connected directly

to VSS.

AA17

AA16

Y17

W17

V18

USB0_DM

USB0_DP

USB0_ID

USB0_RCALIB

USB0_VBUS

If USB0 is not used, leave unconnected.

Note: The USB0_RCALIB pin can only be left unconnected when

VDDA_0P85_USB0, VDDA_1P8_USB0, and VDDA_3P3_USB0

are connected to VSS. The USB0_RCALIB pin must be

connected to VSS through the appropriate external resistor when

VDDA_0P85_USB0, VDDA_1P8_USB0, and VDDA_3P3_USB0 are

connected to a power source.

G13

VMON_VSYS

If VMON_VSYS is not used, this ball must be connected directly to

VSS.

F14

E15

VMON_1P8_SOC

VMON_3P3_SOC

If VMON_1P8_SOC and VMON_3P3_SOC are not used to monitor

the SOC power rails, these balls must still be connected to their

respective 1.8-V and 3.3-V power rails.
