Input thresholds:

1The module is qualified for this temperature range. Functionality has been tested form –40 to +80° with a small number of samples. Components are specified form –20°C to 70°C. Radio performance decreases with rising temperature.

2PIO terminals have weak pull-down resistors (1/10th current of standard pull-down resistors).
