A.2 Rabbit 4000 DC Characteristics
Stresses beyond those listed in Table A-3 may 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-4 outlines the DC characteristics for the Rabbit 4000 at 3.3 V over the recom-
mended operating temperature range from T
