MiFare one card introduced
First, MiFare one IC S70 key indicators
¡ñ capacity of K-32 EEPROM
¡ñ divided into 40 sectors, 32 sectors in which each sector storage capacity of 64 bytes, and is divided into four, each of 16 bytes; eight sectors in the storage capacity for each sector 256 words Festival is divided into 16, 16 bytes of each block; to block access unit
¡ñ each sector there are a group of independent passwords and access control
¡ñ Each card has a unique serial number for 32
¡ñ a mechanism for conflict prevention, support for multi-card operation
¡ñ no power supply, comes with the antenna, embedded encryption control logic and communication logic circuit
¡ñ data retention period of 10 years can be rewritten 100,000 times, unlimited Reading
¡ñ Operating Temperature: -20 ℃ to 50 ℃ (humidity of 90%)
¡ñ frequency: 13.56MHZ
¡ñ communication rate: 106 KBPS
¡ñ literacy distance: within 10 cm (and the reader)
Second, M1 RF card and reader communication
Icon below:
Third, working principle
Electric card by only one part of the antenna and ASIC components.
Antenna: card antenna is only a few group wound coil, it is appropriate to IS0 card in the package.
ASIC: the ASIC card from a high-speed (106KB baud rate) RF interface, a control unit and an 8-K EEPROM components.
Principle: M1 to the card reader, a group of fixed-frequency electromagnetic waves, card there is a series resonant LC circuit, the frequency with the launch of the writing - the same frequency in the electromagnetic wave excitation, the resonant LC resonant circuit, With capacitance of the charge, in the other end of the capacitor, then there is a single electronic wizard-pump, the capacitive charge to another within the storage capacitor, when the accumulated charge to 2 V, the capacitance can be used as a Power to provide work for other circuit voltage, will launch the card data or access the data read and write.
