Controller Features

Versal

• The two GPIO controllers have the same functionality. There are a total of 174 channels in two controllers: PMC GPIO controller:

  • Two banks (26 channels each) to PMC MIO

  • Two banks (32 channels each) to PL EMIO

LPD GPIO controller:

• • One bank (26 channels) to LPD MIO

  • One bank (32 channels) to PL EMIO

• The function of each GPIO can be dynamically programmed on an individual or group basis.

• Enable, bit or bank data write, output enable and direction controls.

• Programmable interrupts on individual GPIO basis

  • Status read of raw and masked interrupt.

  • Selectable sensitivity: Level-sensitive (High or Low) or edge-sensitive (positive, negative, or both).

ZYNQMP

• 78 GPIO signals for device pins.
  • Routed through the MIO multiplexer.
  • Outputs are 3-state capable.
• 288 GPIO signals between the PS and PL through the EMIO interface.
  • 96 inputs.
  • 192 outputs (96 true outputs and 96 output enables).
• I/O interface is organized into 6 banks(3 MIO and 3 EMIO)
• Interface control registers are grouped by bank {0:5}.
• Input values are read using the six DATA_RO_x registers.
• The function of each GPIO can be dynamically programmed on an individual or group basis.
• Enable, bit or bank data write, output enable and direction controls.
• Programmable interrupts on individual GPIO basis.
  • Status read of raw and masked interrupt.
  • Selectable sensitivity: Level-sensitive (High or Low) or edge-sensitive (positive, negative, or both).
