(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If used outside the Section 7.3, Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.

(2) All voltage values are with respect to their associated VSS or VSSA_x, unless otherwise noted.

(3) This parameter applies to all IO pins which are not fail-safe and the requirement applies to all values of IO supply voltage. For example, if the voltage applied to a specific IO supply is 0 volts the valid input voltage range for any IO powered by that supply will be –0.3 to +0.3 volts. Special attention should be applied anytime peripheral devices are not powered from the same power sources used to power the respective IO supply. It is important the attached peripheral never sources a voltage outside the valid input voltage range, including power supply ramp-up and ramp-down sequences.

(4) For current pulse injection:
Pins stressed per JEDEC JESD78E (Class II) and passed with specified I/O pin injection current and clamp voltage of 1.5 times maximum recommended I/O voltage and negative 0.5 times maximum recommended I/O voltage.
For overvoltage performance:
Supplies stressed per JEDEC JESD78E (Class II) and passed specified voltage injection.

(5) For tape and reel the storage temperature range is [–10°C; +50°C] with a maximum relative humidity of 70%. TI recommends returning to ambient room temperature before usage.

(6) VDD is the voltage on the corresponding power-supply pin(s) for the IO.

(7) An external resistor divider is required to create the VMON input value that triggers with V_TH = 0.45 when the V_SYS level reaches the minimum allowed threshold. A series resistor R2 (VMON_ER_VSYS = V_SYS × R1 / (R1 + R2)) of at least 10kΩ is recommended to limit current.

(8) The VMON1_ER_VSYS pin provides a way to monitor the system power supply. For more information, see Section 9.3.4 System Power Supply Monitor Design Guidelines.

(9) An external resistor divider is required to limit the voltage applied to this device pin. For more information, see Section 9.3.3, USB VBUS Design Guidelines.

(10) A single 1.1V source must drive all three VDDS_DDR, VDDS_DDR_BIAS, VDDS_DDR_C supplies.

Fail-safe IO terminals are designed such they do not have dependencies on the respective IO power supply voltage. This allows external voltage sources to be connected to these IO terminals when the respective IO power supplies are turned off. The I2C0_SCL, I2C0_SDA, WKUP_I2C0_SCL, WKUP_I2C0_SDA, MCU_I2C0_SCL, MCU_I2C0_SDA, EXTINTn, MCU_PORz, PORz, VMON1_ER_VSYS, VMON2_IR_VCPU, VMON3_IR_VEXT1P8, VMON4_IR_VEXT1P8, VMON5_ER_VEXT3P3 are the only fail-safe IO terminals. All other IO terminals are not fail-safe and the voltage applied to them should be limited to the value defined by the Steady State Max. Voltage at all IO pins parameter in Section 7.1.
