= -40° to +85° C (unless otherwise noted)
1. Typical values at 25° C. Values are based on characterization and are not tested.
2. Operating Frequency is dependent on the reader circuit design, PCB layout, and component specifications.
SPI Interface timing requirements
An Atmel reference design with 13.560 MHz 50 ppm crystal was used to characterize this parameter.
