卡介绍 MiFare one card
introduced |
一、 MiFare one IC S50
主要指标 First, MiFare one IC S50 key indicators
●容量为8K 位EEPROM ●
capacity of 8-bit EEPROM K
●
分为16 个扇区，每个扇区为4 块，每块16 个字节, 以块为存取单位 ● divided into 16
sectors, each sector for the four, each of 16 bytes to block access
unit
●每个扇区有独立的一组密码及访问控制 ●
each sector there are a group of independent passwords and access
control
●每张卡有唯一序列号，为32 位 ●
Each card has a unique serial number for 32
●具有防冲突机制，支持多卡操作 ● a
mechanism for conflict prevention, support for multi-card
operation

三、工作原理 Third,
working principle
卡片的电气部分只由一个天线和ASIC
组成。 Electric card by only one part of the antenna and ASIC
components.
天线：卡片的天线是只有几组绕线的线圈，很适于封装到IS0
卡片中。 Antenna: card antenna is only a few group wound coil, it
is appropriate to IS0 card in the package.
ASIC
：卡片的ASIC 由一个高速（ 106KB 波特率）的RF 接口，一个控制单元和一个8K 位EEPROM 组成。
ASIC: the ASIC card from a high-speed (106KB baud rate) RF
interface, a control unit and an 8-K EEPROM components.
工作原理：读写器向M1
卡发一组固定频率的电磁波，卡片内有一个LC 串联谐振电路，其频率与讯 Principle: M1 to the card

时，此电容可做为电源为其它电路提供工作电压，将卡内数据发射出去或接取读写器的数据。 To 2 V, the
capacitance can be used as a power source to provide work for other
circuit voltage, will launch the card data or access the data read
and write. |
