Variable Voltage I/O
The device’s digital I/O pins are variable voltage, allowing them to take advantage of low power savings
from shrinking technologies. These pins can operate at +2.5V or 3.3V. The applied I/O voltage must
maintain its value within the tolerances specified in Chapter 5, "Operational Characteristics". Varying
the voltage up or down after the transceiver has completely powered-on can cause errors in the
transceiver operation. Refer to Chapter 5, "Operational Characteristics," on page 82 for additional
information.
