New NFC reader evaboard ST25R3911B-DISCO

ST25R3911B-DISCO is a kit for ST25R3911B high performance HF reader / NFC initiator with 1.4 W output power, VHBR and AAT.

The ST25R3911B-DISCO is a ready-to-use kit featuring the ST25R3911B, an highly integrated HF reader / NFC initiator IC.

The ST25R3911B-DISCO can be operated as ISO18092 (NFCIP-1) active and passive initiator, ISO18092 (NFCIP-1) active target, ISO 14443A and B reader including very high bit rates (VHBR), long range ISO15693 and FeliCa™ reader.
Implementation of other standard and custom protocols like MIFARE™ Classic is possible using the AFE and implementing framing in the external microcontroller (stream and transparent modes).

The ST25R3911B-DISCO addresses a wide range of applications such as access control, ticketing, industrial, medical and consumer, where users need optimal RF performance and flexibility combined with low power consumption.

It contains a low power capacitive sensor that can be used for ultra-low power wakeup without switching on the reader field.
Traditional inductive wakeup with the choice of amplitude or phase measurement can be used as well.

The automatic antenna tuning (AAT) technology enables operation close to metallic parts and/or in changing environments.
The available software visually displays the impact of AAT, thus enabling an easy evaluation of the feature.
