Note 1

There are two types of pads, namely Type A and Type B. Type A is a normal IO pad with a Schmitt

trigger on input while Type B has an extra RC Filter with a cutoff frequency of 100 kHz

Note 2

This pin is also used for the communication to the internal SPI FLASH

Characteristics

All MIN/MAX specification limits are guaranteed by design, production testing and/or statistical

characterization. Typical values are based on characterization results at default measurement

conditions and are informative only.

measurements are done with standard RF measurement equipment.

Absolute Maximum Ratings

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to

the device. These are stress ratings only, so functional operation of the device at these or any other

conditions beyond those indicated in the operational sections of the specification are not implied.

Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability.
