Stresses beyond those listed in Table A-3may cause permanent damage. The ratings are stress ratings only, and functional operation of the Rabbit 4000 chip at these or any other conditions beyond those indicated in this section is not implied. Exposure to the absolute maximum rating conditions for extended periods may affect the reliability of the Rabbit 4000 chip.

Table A-4outlines the DC characteristics for the Rabbit 4000 at 3.3 V over the recom- mended operating temperature range from TA = –40°C to +85°C, VDDIO = 3.0 V to 3.6 V.
