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.
