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 current per pin at full AC switching speed. Full AC switching assumes a 25.8 MHz
CPU clock and capacitive loading on address and data lines of less than 100 pF per pin.
Address pin A0 and data pin D0 are rated at 16 mA each. Pins A1–A12 and D1–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 RabbitCore 2000.
Some of the values listed are different from those listed in the Rabbit 2000 Microproces-
sor User’s Manual to take into account external loading of the Rabbit 2000 while it is part
of the RCM2000. Loads that exceed the values listed above need to be buffered.

The maximum DC output drive on I/O buffers must be adjusted to take
into consideration the current demands made my AC switching 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.
