2.5 Interface Headers
2.5.1 Digilent Pmod™ Compatible Expansion Headers (2x6)
The Carrier has 12 Digilent Pmod™ right angle 0.1” female headers (2x6). These
connections include eight user I/O plus an adjustable voltage derived from VCCIO_34
and VCCIO_35 power supplies. These power supplies are jumper selectable to
provide 1.8V, 2.5V or 3.3V. When 3.3V is selected, the connectors are Pmod
compatibale. All Pmod™ connections with the exception of the PS Pmod™ are
matched differential Pmod™ connections and are routed differentially within the
connector and with reference to one another to ensure high speed signal integrity.
• The Digilent Pmod™ compatible interface connects to Zynq banks 500, 34, 35
and 13. Bank 13 is only available on the 7Z020 version MicroZed.
• The PS Pmod attached to bank 500 can be used for PJTAG access (MIO[10-
13]) as well as utilizing nine other hardened MIO peripherals (SPI, GPIO, CAN,
I2C, UART, SD, QSPI, Trace, Watchdog). NOTE: The PS Pmod™ is also
accessible on MicroZed and only can be used by one Digilent Pmod™
compatible interfaces at one time. The PS Pmod is 3.3V only.
• 7Z020 MicroZed only: Pmods™ ,JY and JZ, are sourced by Bank 13 and thus
only available when MicroZed is populated with a 7Z020 device. Pmod™ JZ
only has 7 pin connections, thus this Pmod™ interface cannot interface to
QSPI or SD interface per the Digilent Pmod™ specification.
