All electrical parameters in all tables are specified under the conditions listed in Table 3.1 Recommended Operating Conditions on page 10, unless stated otherwise.

Stresses above those listed in 3.3 Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the devices at those or any other conditions above those indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. For more information on the available quality and reliability data, see the Quality and Reliability Monitor Report at http://www.silabs.com/support/quality/pages/ default.aspx.

Table 3.10. Absolute Maximum Ratings

1. Exposure to maximum rating conditions for extended periods may affect device reliability.

2. On devices without a VIO pin, V IO = V DD

Table 3.1. Recommended Operating Conditions

1. Standard USB compliance tests require 3.0 V on VDD for compliant operation.
2. All voltages with respect to GND.
3. On devices without a VIO pin, V IO = V DD .
4. GPIO levels are undefined whenever VIO is less than 1 V.

Table 3.9. Thermal Conditions

1. Thermal resistance assumes a multi-layer PCB with any exposed pad soldered to a PCB pad.
