64 RabbitCore RCM3600
A.4 I/O Buffer Sourcing and Sinking Limit
Unless otherwise specified, the Rabbit I/O buffers are capable of sourcing and sinking
6.8 mA of current per pin at full AC switching speed. Full AC switching assumes a
22.1 MHz CPU clock and capacitive loading on address and data lines of less than 100 pF
per pin. The absolute maximum operating voltage on all I/O is 5.5 V.
Table A-7 shows the AC and DC output drive limits of the parallel I/O buffers when the
Rabbit 3000 is used in the RCM3600.
