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
29.4 MHz CPU clock and capacitive loading on address and data lines of less than 70 pF
per pin. The absolute maximum operating voltage on all I/O is 5.5 V.
Table A-6 shows the AC and DC output drive limits of the parallel I/O buffers when the
Rabbit 3000 is used in the RCM3200.
Under certain conditions, the maximum instantaneous AC/DC sourcing or sinking current
may be greater than the limits outlined in Table A-6. The maximum AC/DC sourcing cur-
rent can be as high as 12.5 mA per buffer as long as the number of sourcing buffers does
not exceed three per V
maximum AC/DC sinking current can be as high as 8.5 mA per buffer as long as the num-
ber of sinking buffers does not exceed three per V
between pads. The V
28 mA. All these analyses were measured at 100°C.
