MFRC531 - Brand New NXP Semiconductors RFID, RF Access, Monitoring ICs
-
Description
The MFRC531 is a highly integrated reader IC for contactless communication at 13.56 MHz. It utilizes a modulation and demodulation concept that is integrated for all kinds of passive contactless communication methods and protocols at this frequency. The MFRC531 is pin-compatible to the MFRC500, MFRC530, and SLRC400.
