13. Pmod Ports
Pmod ports are 2×6, right-angle, 100-mil spaced female connectors that mate with
standard 2×6 pin headers. Each 12-pin Pmod port provides two 3.3V VCC signals (pins
6 and 12), two Ground signals (pins 5 and 11), and eight logic signals, as shown in
Figure 13.1. The VCC and Ground pins can deliver up to 1A of current, but care must
be taken not to exceed any of the power budgets of the on-board regulators or the
external power supply (as described in the

Digilent produces a large collection of Pmod accessory boards that can attach to the
Pmod ports to add ready-
made functions like A/D’s, D/A’s, motor drivers, sensors, and
for more information. The vivado-library and
vivado-hierarchies repositories on the
contains pre-made IP cores for
many of these Pmods that greatly reduces the work of integrating them into your
project. See the Pmod-related tutorials on the Eclypse Z7 Resource Center for help
using them.
The Eclypse Z7's two Pmod ports are connected to the Zynq PL via high-speed down
translation and protection circuitry. When used as outputs, the Pmod pins are driven at
3.3V. When used as inputs, the Pmod pins are 5V tolerant. The maximum
recommended voltage applied to these pins is 5.5V, though the inline resettable fuses
will protect the FPGA pins from damage.
