  1. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
  2. All voltage values are with respect to their associated VSS or VSSA_x.
  3. Not available on the ZCE package. VDD_MPU is merged with VDD_CORE on the ZCE package.
  4. This supply is sourced from an internal LDO when RTC_KALDO_ENn is low. If RTC_KALDO_ENn is high, this supply must be sourced from an external power supply.
  5. During functional operation, this pin is a no connect.
  6. Not available on the ZCE package.
  7. This terminal is connected to a fail-safe I/O and does not have a dependence on any I/O supply voltage.
  8. This parameter applies to all I/O terminals which are not fail-safe and the requirement applies to all values of I/O supply voltage. For example, if the voltage applied to a specific I/O supply is 0 volts the valid input voltage range for any I/O powered by that supply will be –0.5 to +0.3 V. Apply special attention anytime peripheral devices are not powered from the same power sources used to power the respective I/O 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.
  9. This terminal is connected to analog circuits in the respective USB PHY. The circuit sources a known current while measuring the voltage to determine if the terminal is connected to VSSA_USB with a resistance less than 10 Ω or greater than 100 kΩ. The terminal should be connected to ground for USB host operation or open-circuit for USB peripheral operation, and should never be connected to any external voltage source.
  10. Based on JEDEC JESD78D [IC Latch-Up Test].
  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.

    12. Fail-safe I/O terminals are designed such they do not have dependencies on the respective I/O power supply voltage. This allows external voltage sources to be connected to these I/O terminals when the respective I/O power supplies are turned off. The USB0_VBUS and USB1_VBUS are the only fail-safe I/O terminals. All other I/O 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 I/O pins parameter in Section 5.1.

5.8 Thermal Resistance Characteristics for ZCE and ZCZ Packages

Failure to maintain a junction temperature within the range specified in Section 5.5 reduces operating lifetime, reliability, and performance—and may cause irreversible damage to the system. Therefore, the product design cycle should include thermal analysis to verify the maximum operating junction temperature of the device. It is important this thermal analysis is performed using specific system use cases and conditions. TI provides an application report to aid users in overcoming some of the existing challenges of producing a good thermal design. For more information, see AM335x Thermal Considerations.

Table 5-12 provides thermal characteristics for the packages used on this device.

5.9 External Capacitors

To improve module performance, decoupling capacitors are required to suppress the switching noise generated by high frequency and to stabilize the supply voltage. A decoupling capacitor is most effective when it is close to the device, because this minimizes the inductance of the circuit board wiring and interconnects.

Table 5-13 summarizes the Core voltage decoupling characteristics.

5.9.2 Output Capacitors

Internal low dropout output (LDO) regulators require external capacitors to stabilize their outputs. These capacitors should be placed as close as possible to the respective terminals of the AM335x device. Table 5-15 summarizes the LDO output capacitor recommendations.
