STSW-ST25RFAL001
2/4 DB3939 Rev 1
Description
STSW-ST25RFAL001 is the implementation of the RF/NFC abstraction layer (RFAL) for the
ST25R3911B.
The RFAL simplifies the development of applications by encapsulating device and protocol
details.
The RFAL provides a common interface that makes the upper software layers independent
from the used ST25R device. The RFAL with the same APIs is available for all ST25R
devices, thus simplifying the software efforts when migrating from one device to another.
