E.2 Header J6
The connector is a 2 × 5, 0.1" pitch header suitable for connecting to an IDC header
socket, with the following pin allocations.
All Parallel Port F lines (pins 1 to 8) are pulled up internally to +3.3 V via 100 k
resis-
tors. When used as outputs, the port pins will sink up to 6 mA at a VOL of 0.4 V max.
(0.2 V typ), and source up to 6 mA at a VOH of 2.2 V typ. When used as inputs, all pins
are 5 V tolerant.
As the outputs from Parallel Port F are compatible with 3.3 V logic, buffers may be
needed when the external circuit drive requirements exceed the 2.2 V typ logic high and/or
the 6 mA maximum from the Rabbit 3000. The +5 V supply output is provided for supply-
ing interface logic. When used as inputs, the pins on header J6 do not require buffers
unless the input voltage will exceed the 5 V tolerance of the processor pins. Usually, a
simple resistive divider with catching diodes will suffice if higher voltage inputs are
required. If the outputs are configured for open-drain operation, they may be pulled up to
+5 V (while observing the maximum current, of course).
