Introduction[edit | edit source]

This chapter contains the pinout description of the BORA Lite SOM, grouped in two tables (odd and even pins) that report the pin mapping of the 204-pin SO-DIMM BORA Lite connector. Each row in the pinout tables contains the following information:

  • Pin: reference to the connector pin
  • Pin Name: pin (signal) name on the Bora connectors
  • Internal connections: connections to the Bora components
    • CPU.<x> : pin connected to CPU (processing system) pad named <x>
    • FPGA.<x>: pin connected to FPGA (programmable logic) pad named <x>
    • CAN.<x> : pin connected to the CAN transceiver
    • LAN.<x> : pin connected to the LAN PHY
    • USB.<x> : pin connected to the USB transceiver
    • NAND.<x>: pin connected to the flash NAND
    • NOR.<x>: pin connected to the flash NOR
    • SV.<x>: pin connected to voltage supervisor
    • MTR: pin connected to voltage monitors
  • Ball/pin #: Component ball/pin number connected to signal
  • Supply Group: Power Supply Group
  • Type: pin type
    • I = Input
    • O = Output
    • D = Differential
    • Z = High impedance
    • S = Power supply voltage
    • G = Ground
    • A = Analog signal
  • Voltage: I/O voltage levels
