Application Card Interface

The common processor card includes an application connector to interface different pin-multiplexed functions of the PRG0 and PRG1 I/O groups of the AM65x processor. The main purpose of the application card is to highlight the industrial capabilities of the AM65x processor. All the signals associated with the PRG0 and PRG1 interface are routed to the application connector.

The interfaces provided on the application connector are RGMII, UART, MCAN, I2C, SPI, McASP, ADC, and PWM signals. The PRG0 signals are multiplexed with the McASP1 signals of the HDMI/GPMC card. Resistor options are provided to allow for the selection of the required interface, as shown in Figure 3-21. Table 3-27 lists the resistors that are mounted or demounted to select RGMII signals on the application connector.

The card presence detect signal from the application card is connected to the I/O expander, which in turn is connected to the WKUP I2C0 port of the AM65x processor.

The 120-pin connector pin-out is given in Table 3-28.
