2 EVM Overview

The features of this EVM are as follows:

  • Single power-supply input for basic operation
  • Example push-pull transformer and 58-kHz transducer
  • LIN master transceiver
  • RS-232 transceiver for UART testing and debug
  • PC control with a graphical user interface and USB communications board

For a given PGA450Q1EVM installation, the following items apply:

  • The PGA450Q1EVM can have either a through-hole or surface-mount transformer installed on it. When a through-hole transformer is installed, ensure that the case corners are not touching the surface mount pads.
  • The PGA450Q1EVM can be used to drive either a single-ended or push-pull transformer. The selection of the drive method is achieved through jumper selection.
  • The USB communication board 5-V power supply must be enabled for LIN communication to work. The 5-V power supply provides power to the LIN master transceiver installed on the board.
  • In order to communicate with the PGA450-Q1 device using SPI, the 8051W inside the device must be put in the reset state.
