2.1.1 Operating Conditions

Stresses beyond the operating conditions listed in Table 2-1 may cause permanent damage to the device.

Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Absolute Maximum Ratings are stress ratings only; functional operation of the device at these or any other conditions beyond those listed under the Recommended Operating Conditions specified in Table 2-3 is not implied.

Note:
  1. All parameters representing voltages are measured with respect to GND unless otherwise specified.
  2. The following 1.5V supplies should be connected together while following proper noise filtering practices: VCC, VCC15A, and VCC15ADCx.
  3. VPP can be left floating during operation (not programming mode).
  4. The ranges given here are for power supplies only. The recommended input voltage ranges specific to each I/O standard are given in Table 2-19. VCCxxxxIOBx should be at the same voltage within a given I/O bank.
  5. The following 3.3V supplies should be connected together while following proper noise filtering practices: VCC33A, VCC33ADCx, VCC33AP, VCC33SDDx, VCCMAINXTAL, and VCCLPXTAL.
