ADVANCE INFORMATION
Ball Number | Ball Name | Pin Connectivity Requirements |
---|---|---|
F3 B10 |
MCU_ERRORn TRSTn |
Each of these balls must be connected to VSS through separate external pull resistors to ensure the inputs associated with 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. |
C9 C10 D9 P3 A10 D10 C11 |
EMU0 EMU1 MCU_RESETz EXTINTn TCK TDI TMS |
Each of these balls must be connected to the corresponding power supply(1) through separate external pull resistors to ensure the inputs associated with 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. |
B9 A8 |
WKUP_I2C0_SCL WKUP_I2C0_SDA |
Each of these balls must be connected to the corresponding power supply(1) through separate external pull resistors to ensure the inputs associated with these balls are held to a valid logic high level. |
N10 P10 R9 |
VDDA_CORE_USB VDDA_1P8_USB VDDA_3P3_USB |
If USB0 is not used, each of these balls must be connected directly to VSS. |
W9 V9 V8 U9 |
USB0_DM USB0_DP USB0_RCALIB USB0_VBUS |
If USB0 is not used, leave the DM, DP, and VBUS balls unconnected. Note: The USB0_RCALIB ballcan only be left unconnected when VDDA_CORE_USB, VDDA_1P8_USB, and VDDA_3P3_USB are connected to VSS. The USB0_RCALIB ball must be connected to VSS through an appropriate external resistor when VDDA_CORE_USB, VDDA_1P8_USB, and VDDA_3P3_USB are connected to power sources. |
H8 | VMON_ER_VSYS | If VMON_ER_VSYS is not used, this ball must be connected directly to VSS. |
J6 | VMON_1P8_SOC | If VMON_1P8_SOC is not used to monitor the SOC power rail, this ball must remain connected to a 1.8-V power supply. |
H5 | VMON_3P3_SOC | If VMON_3P3_SOC is not used to monitor the SOC power rail, this ball must remain connected to a 3.3-V power rail or connected directly to VSS. |
A3 A12 B3 E2 E4 G3 W8 |
RSVD_A3 RSVD_A12 RSVD_B3 RSVD_E2 RSVD_E4 RSVD_G3 RSVD_W8 |
Each of these balls must be left unconnected. |
LVCMOS PIN | Any LVCMOS Voltage Buffer Pin | If an associated IOMUX pad configuration register exists for a given pin, it may remain unconnected. After PORz, the LVCMOS voltage buffer is configured to a default state compatible with an unconnected ball. |
