7.5.1 Strap Configuration

The DP83867 uses many of the functional pins as strap options to place the device into specific modes of operation. The values of these pins are sampled at power up or hard reset. During software resets, the strap options are internally reloaded from the values sampled at power up or hard reset. The strap option pin assignments are defined below. The functional pin name is indicated in parentheses.

The strap pins supported are 4-level straps, which are described in greater detail below.

Note:

Because strap pins may have alternate functions after reset is deasserted, they should not be connected directly to VDD or GND.

Configuration of the device may be done through the 4-level strap pins or through the management register interface. A pullup resistor and a pulldown resistor of suggested values may be used to set the voltage ratio of the 4-level strap pin input and the supply to select one of the possible selected modes.

The MAC interface pins must support I/O voltages of 3.3V, 2.5V, and 1.8V. As the strap inputs are implemented on these pins, the straps must also support operation at 3.3V, 2.5V, and 1.8V supplies.

For more information about configuring 4-level straps, see the Configuring Ethernet Devices with 4-Level Straps application report (SNLA258).

All straps have a 9kΩ ±25% internal pulldown resistor. The voltage at strap pins should be between the Vmin and Vmax mentioned in the Target Voltage column in Table 7-4. Strap resistors with 1% tolerance are recommended.

The following tables describes the DP83867 configuration straps:
