(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 Recommended Operating Conditions, but within the Absolute Maximum Ratings, the device may not be fully

functional, and may affect device reliability, performance, functionality, and shorten the device lifetime.

(2)

All voltage values are with respect to VSS, unless otherwise noted.

(3)

The absolute maximum ratings for these fail-safe pins depends on their IO supply operating voltage. Therefore, this value is also

defined by the maximum VIH value found in the I2C Open-Drain, and Fail-Safe (I2C OD FS) Electrical Characteristics section, where

the electrical characteristics table has separate parameter values for 1.8-V mode and 3.3-V mode.

(4)

The VMON_VSYS pin provides a way to monitor the system power supply. For more information, see the System Power Supply

Monitor Design Guidelines.

(5)

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.

(6)

An external resistor divider is required to limit the voltage applied to this device pin. For more information, see the USB VBUS Design

Guidelines.

(7)

The USB0_ID pin is connected to analog circuits in the USB0 PHY. The analog circuits source a known current while measuring

voltage, to determine the resistance value (RID), if connected to VSS through a resistor. This pin should be connected to VSS for USB

host operation, or left unconnected for USB device operation, and should never be connected to any external voltage source.

(8)

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

(9)

For current pulse injection (I-Test):

•

Pins stressed per JEDEC JESD78 (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.

(10) For over-voltage performance (Over-Voltage (OV) Test):

•

Supplies stressed per JEDEC JESD78 (Class II) and passed specified voltage injection.

(11) 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.

Fail-safe IO terminals are designed without any 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.

MCU_I2C0_SCL, MCU_I2C0_SDA, I2C0_SCL, I2C0_SDA, EXTINTn, VMON_1P8_MCU, VMON_1P8_SOC,

VMON_3P3_MCU, VMON_3P3_SOC, and MCU_PORz 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.
