A.4 I/O Buffer Sourcing and Sinking Limit
Unless otherwise specified, the Rabbit I/O buffers are capable of sourcing and sinking 8 mA of cur-
rent 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. Pins A0–A12 and D0–D7
are each rated at 8 mA. The absolute maximum operating voltage on all I/O is VDD + 0.5 V, or 5.5 V.
Table A-5 shows the AC and DC output drive limits of the parallel I/O buffers when the Rabbit 2000
is used in the RCM2100.

* The maximum DC sourcing current for I/O buffers between VDD
pins is 112 mA.
The maximum DC sinking current for I/O buffers between VSS
pins is 150 mA.

The maximum DC output drive on I/O buffers must be adjusted to
take into consideration the current demands made my AC switch-
ing outputs, capacitive loading on switching outputs, and switching
voltage.
The current drawn by all switching and nonswitching I/O must
not exceed the limits specified in the first two footnotes.
