5.4 Pin Connectivity Requirements

Ball Number

Ball Name

Pin Connectivity Requirements

SAFETY_ERRORn

This pin must be connected to ground (VSS) through a separate external

pull resistor to make sure the pin is 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.

J16

RSVD_J16

This pin must be connected to 1.2V supply (VDD).

RSVD_T4

RSVD_U1

Each of these pins must be connected (shorted) directly to ground (VSS)

RSVD_U3

RSVD_V2

Each of these pins must be left unconnected.

P15(1)

RSVD_P15(1)

ZCZ_S and ZCZ_F Package only. This pin must be left unconnected

TCK

TDI

TMS

Each of these pins must be connected to the corresponding power supply

through separate external pull resistors to make sure 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.

A13

B13

I2C0_SCL

I2C0_SDA

Each of these pins must be connected to the corresponding power supply

through separate external pull resistors to make sure these balls are held to

a valid logic high level.

A11

C10

QSPI0_D0 (SOP0)

QSPI0_D1 (SOP1)

SPI0_CLK (SOP2)

SPI0_D0 (SOP3)

Each of these pins must be connected to the corresponding power supply

or ground (VSS) through separate external pull resistors to make sure these

balls are held to a valid logic high or low level as appropriate to select the

desired device boot mode.

U16

T15

ADC_CAL0

ADC_CAL1

If all ADCx_AINy inputs for all ADC instances (ADC[0:4]_AIN[0:5]) are not

used, the ADC_CAL[0:1] analog pins must be connected (shorted) directly to

ground (VSS).

VSYS_MON

If VSYS_MON is not used, this pin can be connected (shorted) directly to

ground (VSS).

ADC ZCZ PIN

ADC[0:4]_AIN[0:5]

Any unused ADCx_AINy input pin for any ADC instance (ADC[0:4]_AIN[0:5])

must be connected (shorted) directly to ground (VSS).

ADC_R ZCZ PIN

ADC_R[0:1]_AIN[0:3]

Any unused ADC_Rx_AINy input pin for any ADC_R instance

(ADC_R[0:1]_AIN[0:3]) must be connected (shorted) directly to ground

(VSS).

LVCMOS ZCZ PIN

Any LVCMOS Voltage Buffer

If an associated IOMUX pad configuration register exists for a given pin,

the pin can remain unconnected. After PORz, the LVCMOS voltage buffer is

configured to a default state compatible with an unconnected ball.

GPIO69(2)

GPIO70(2)

ZCZ_F Package only. Each of these pins must be left unconnected with no

PCB trace.

L1(2)

GPIO8(2)

ZCZ_F Package only. This pin must be connected to VDDS33 through

a separate external 4.7kΩ pull resistor placed as close to the device as

possible.

J3(2)

GPIO64(2)

ZCZ_F Package only. OSPI_RESET_OUT0 connection to PORz. To reset

the on-die OSPI flash module OSPI_RESET_OUT0 must be connected to an

open-drain equivalent of PORz.
