The K24 SOM leverages the XCK24-UBVA530-2LV-C/XCK24-UBVA530-2LV-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 (XCK24 in commercial (C) grade or industrial (I) grade)
  • 2 GB 32-bit wide, 1066 Mb/s LPDDR4 memory, ECC support for I grade, no ECC support for C grade
  • Integrated non-volatile memory devices
    • 512 Mb QSPI
    • 32 GB eMMC
    • 64 Kb EEPROM
  • TPM2.0 security module
  • One 240-pin connector and one 40-pin connector with access to user-configurable I/O. The 240-pin connector is backward compatible to the K26 SOM 240_1 connector:
    • PS MIO
    • PS-GTR transceivers
    • PS I2C platform control bus
    • PL HPIO
    • PL HDIO
    • 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 interface plate

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
  • Security features and module
