MFRC53101T

The MFRC53101T is member of a new family of highly integrated reader ICs for contactless communication at 13.56 MHz. This reader IC family uses an distinctive modulation and demodulation concept completely combined for all kin ds of passive contactless communication methods and protocols at 13.56 MHz. The MFRC53101T supports all layers of the ISO14443 including the type A and type B communication scheme. The MFRC53101T supports contactless com munication using MIFARE higher baudrates.The internal transmitter part can drive an antenna designed for proximity operating distance (up to 100 mm) directly without additional active circuitry.

Features of the MFRC53101T are:(1)highly integrated analog circuitry to demodulate and 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) supports ISO 14443;(5)supports MIFARE dual interface card ICs and supports MIFARE classic protocol;(6)supports contactless communication with higher baudrates up to 424kHz;(7)crypto1 and secure non-volatile internal key memory;(8) pin-compatible to the MF RC500, MF RC530 and the SL RC400.

The electrical specification of the MFRC53101T can be summarized as:(1):digital supply voltage is 3.0V min, 3.3V typ and 3.6 V max;(2):analog supply voltage is 4.5V min, 5.0V typ and 5.5 V max;(3):transmitter supply voltage is 3.3V min, 5.0V typ and 5.5 V max;(4):operating digital supply current is 25 mA of idle command; (5):operating analog sup ply current is 25mA of idle command,receiver on;(6):hard reset via reset pin is 1 A when it is less than1000 s;(7): soft reset via register setting is 1 A when it is less than 1000 s.etc.
