The K26 SOM leverages the XCK26-SFVC784-2LV-C/I, a custom-built Zynq UltraScale+ MPSoC that runs optimally (and exclusively) on the SOM. It provides an embedded processing system (PS) with tightly integrated programmable logic and a rich set of configurable I/O capabilities. The SOM hardware features include:

  • Zynq UltraScale+ MPSoC (XCK26 in commercial (C) grade or industrial (I) grade)
  • 4 GB 64-bit wide, 2400 Mb/s memory
  • Integrated non-volatile memory devices
    • 512 Mb QSPI
    • 16 GB eMMC
    • 64 Kb EEPROM
  • TPM2.0 security module
  • Two 240-pin connectors with access to user-configurable I/O:
    • PS MIO
    • PS-GTR transceivers
    • PS I2C platform control bus
    • PL HPIO
    • PL HDIO
    • PL GTH transceivers
    • Sideband platform signals
    • Power and power sequencing signals
  • Integrated and flexible power design
    • SOC power supplies derived from a single +5V input
    • PL I/O supplies customized through carrier card defined power rails
  • Compact mechanical size with integrated thermal heat spreader

The following sections provide a more detailed description of:

  • Functional interfaces and input/output
  • MPSoC processing system (PS)
  • MPSoC programmable logic (PL)
  • Boot sources and storage devices
