MFRC53101T

Product Summary

The MFRC53101T is member of a new family of highly integrated reader ICs for contactless communication at 13.56 MHz. This reader IC family utilises an outstanding modulation and demodulation concept completely integrated for all kinds of passive contactless communication methods and protocols at 13.56 MHz. The MFRC53101T is pin- compatible to the MF RC500, the MF RC530 and the SL RC400. The MFRC53101T supports all layers of the ISO14443 including the type A and type B communication scheme The MFRC53101T supports contactless communication using MIFARE Higher Baudrates. The internal transmitter part is able to drive an antenna designed for proximity operating distance (up to 100 mm) directly without additional active circuitry. The receiver part provides a robust and efficient implementation of a demodulation and decoding circuitry for signals from ISO14443 compatible transponders. The digital part handles the complete ISO14443 framing and error detection (Parity & CRC). Additionally it supports the fast MIFARE Classic security algorithm to authenticate MIFARE Classic (e.g. MIFARE Standard, MIFARE Light) products. A comfortable parallel interface, which can be mdirectly connected to any 8-bit μ-Processor gives high flexibility for the reader/terminal design. Additionally a SPI compatible interface is supported.
