MFRC50001T

The MFRC50001T is one member of the MFRC500 series.The MFRC500 is member of a new family of highly integrated reader ICs for contactless communication on 13,56MHz. This new reader IC family utilises an outstanding modulation and demodulation concept completely integrated for all major kinds of passive contactless communication methods and protocols on 13,56MHz.The MFRC500 is tailored to fit the requirements of various applications using contactless communication based on ISO/IEC 14443A standard where cost-effectiveness, small size,high performance with a single voltage supply are important.

Features of the MFRC50001T are:(1)highly integrated analog circuitry to decode card response; (2)buffered output drivers to connect an antenna with minimum number of external components; (3)proximity operating distance (up to 100 mm); (4)fast internal oscillator buffer to connect 13.56MHz quartz; (5)clock frequency monitoring; (6)hard reset with low power functions; (7)power down mode per software; (8)parallel Controller interface with internal address latch and IRQ line; (9)automatic detection of parallel C interface type; (10)comfortable send and receive FIFO buffer; (11)anti-collision procedure support; (12)bit- and byte-oriented framing; (13)unique serial number; (14)onboard timer circuit.

The absolute maximum ratings of the MFRC50001T can be summarized as:(1)digital supply voltage:4.5 to 5.5V;(2)analog supply voltage:4.5 to 5.5 V;(3)operating digital supply current:6 mA.The card responds with load modulation of the RF field. The resulting signal picked up by the antenna is coupled out from the antenna matching circuit and forwarded to the RX-pin. Inside the MF RC500 the receiver senses and demodulates the signal and processes it according to the register settings. Data is passed further on to the parallel interface where it is accessible by the -Controller.The correct key for the authentication has to be selected from the secure internal non-volatile key memory and loaded into the internal CRYPTO1 register. Next the authentication command is transmitted to the card.These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury.
