ST25R3911B-DISCO

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

• Based on ST25R3911B HF reader / NFC initiator with 1.4 W output power, supporting VHBR and AAT
• STM32L476RET6 32-bit microcontroller with 512 kB of Flash memory
• 105mm x 52mm, two turns antenna etched on the PCB, and associated VHBR tuning circuit
• Micro-USB connector for communication with the host PC and board powering
• Six LEDs indicating the presence of RF field and the protocol used to communicate
