5.4 Pin Connectivity Requirements

This section describes connectivity requirements for package balls that have specific connectivity requirements and unused package balls.

Note:

All power balls must be supplied with the voltages specified in the Recommended Operating Conditions section, unless otherwise specified.

Note:

For additional clarification, "leave unconnected" or "no connect" (NC) means no signal traces can be connected to these device ball numbers.

Note: See associated AM273x Hardware Design Guide for further details and design context.
Table 5-42 Connectivity Requirements - AM273x ZCE Package
BALL NUMBER BALL NAME CONNECTION REQUIREMENTS
V1 CLKP Crystal oscillator excitation output. Can be attached to external crystal terminal or driven with 1.8 V oscillator output.
U1 CLKM Crystal oscillator excitation input. Can be attached to external crystal terminal. If an external 1.8 V oscillator is used to drive the CLKP pin, this CLKM pin should be attached to VSS. Recommend attaching through pull-down resistor.
T1 VBGAP Should be attached to external 0.047 uF capacitor for proper bandgap voltage operation.
N18, N17, J3, T8 VNWA, VDD_SRAM_1, VDD_SRAM_2, VDD_SRAM_3 All of these power pins must be shorted to common VDD 1.2 V core supply net and provided separate decoupling capacitance on the PCB.
U9 VPP Should be connected to valid e-fuse programming voltage source, or routed to connector. If unused, this should be completely disconnected on the PCB.
K1, L1, L3 WARM_RESET, NERROR_OUT and NERROR_IN WARM_RESET, NERROR_OUT and NERROR_IN are implemented as fail-safe, open-drain I/O. These pins require separate, external pull-up resistor to VIOIN to function correctly.
P4, N3 RESERVED1, RESERVED2 Reserved signals. Should be shorted to VSS.
Table 5-43 Connectivity Requirements - AM273x NZN Package
BALL NUMBER BALL NAME CONNECTION REQUIREMENTS
P1 CLKP Crystal oscillator excitation output. Can be attached to external crystal terminal or driven with 1.8 V oscillator output.
N1 CLKM Crystal oscillator excitation input. Can be attached to external crystal terminal. If an external 1.8 V oscillator is used to drive the CLKP pin, this CLKM pin should be attached to VSS. Recommend attaching through pull-down resistor.
M1 VBGAP Should be attached to external 0.047 uF capacitor for proper bandgap voltage operation.
L13, K14, G3, M6 VNWA, VDD_SRAM_1, VDD_SRAM_2, VDD_SRAM_3 All of these power pins must be shorted to common VDD 1.2 V core supply net and provided separate decoupling capacitance on the PCB.
N7 VPP Should be connected to valid e-fuse programming voltage source, or routed to connector. If unused, this should be completely disconnected on the PCB.
H3, H1, H2 WARM_RESET, NERROR_OUT and NERROR_IN WARM_RESET, NERROR_OUT and NERROR_IN are implemented as fail-safe, open-drain I/O. These pins require separate, external pull-up resistor to VIOIN to function correctly.
L3, K3 RESERVED1, RESERVED2 Reserved signals. Should be shorted to VSS.

Note:

Internal pull resistors are weak and may not source enough current to maintain a valid logic level for some operating conditions. This can be the case when connected to components with leakage to the opposite logic level, or when external noise sources couple to signal traces attached to balls which are only pulled to a valid logic level by the internal resistor. Therefore, external pull resistors are recommended to hold a valid logic level on balls with external connections.

Many of the device IOs are turned off by default and external pull resistors may be required to hold inputs of any attached device in a valid logic state until software initializes the respective IOs. The state of configurable device IOs are defined in the BALL STATE DURING RESET RX/TX/PULL and BALL STATE AFTER RESET RX/TX/PULL columns of the Pin Attributes table. Any IO with its input buffer (RX) turned off is allowed to float without damaging the device. However, any IO with its input buffer (RX) turned on shall never be allowed to float to any potential between VILSS and VIHSS. The input buffer can enter a high-current state which could damage the IO cell if allowed to float between these levels.
