Not only did she find4 it hard to fall asleep, but also she felt her stomach hurt. Suddenly she came up with an idea, “Were I full5, I would have a good sleep easily.”Then she got up and went to the kitchen. There was6 a cabbage, some hams and some eggs in the fridge. No sooner had she taken7 out,what she neede。

8、图,8.1 IC卡的存储器芯片,存储固定信息和消费信息(可修改); 只有与读写器接触时才取得能量;,存储器的性能:,存储器的类型:,EEPROM; 有8个引出端、其中一个为数据I/O端; 信息传送以串行方式进行;,美国ATMEL公司的AT24C01A/02/04/08/16为例:,1. 芯片特点,低电压内部组成AT24C01A(1K:128*8) 双线串行接口(时钟SCL,串行数据SDA)支持ISO/IEC 781610 同步协议高可靠性:10万次、100年,2. 芯片封装,3. EEPROM逻辑图,Q:EEPROM如何读写 ?,器件地址输入端 (标准封装),SCL(串行时钟):SCL上升沿将数据输入到EEPROM芯片,下降沿将EEPROM中的数据读出。
SDA(串行数据):双向串行数据传送端,采用漏极开路驱动,可以进行? 串行控制逻辑:用于区分SCL和SDA。
地址/计数器:形成访问EEPROM的地址,分别 送X译码器进行字选,送Y译码器进行位选。
升压/定时线路:为EEPROM的写入操作提供高电压(12V20V),4. 器件操作,数据和时钟传送:SCL和SDA通常各自通过一。
