X5045中文资料
X5045特性介绍1．特性：可选时间的看门狗定时器。
VCC的降压检测和复位控制5种标准的开始复位电压使用特定的编程顺序即可对低电压检测和复位开始电压进行编程。
复位电压可低至VCC=1V。
省电特性在看门狗打开时，电流小于50uA在看门狗关闭时，电流小10uA在读操作时，电流小2mA不同的型号的器件，其供电电压可以是1.8-3.6V,2.7V-5.5V,4.5V-5.5V。
4K位EEPROM，1，000，000次的擦写周期。
具有数据的块保护功能——可以保护1/4、1/2、全部的EEPROM，当然也可以置于不保护状态。
内建的防误写措施——用指令允许写操作。
——写保护引脚。
时钟可达3.3M。
短的编程时间——16字节的页写模式。
——写时由器件内部自动完成。
——典型的器件写周期为5ms。
2．功能描述：本器件将四种功能合于一体：上电复位控制、看门狗定时器、降压管理以及具有块保护功能的串行EEPROM。
它有助于简化应用系统的设计，减少印制板的占用面积，提高可靠性。
该芯片内的串行EEPROM是具有Xicor公司的块锁保护CMOS串行EEPROM。
它被组织成8位的结构。
它由一个由四线构成的SPI总线方式进行操作，其擦写周期至少有1，000，000次，并且写好的数据能够保存100年。
3．操作方法上电复位当器件通电并超过V TRIP时，X5045内部的复位电路将会提供一个约为200MS的复位脉冲，让微处理器能够正常复位。
降压检测：工作过程中，X5045监测V CC端的电压下降，并且在VCC电压跌落到V TRIP以下时会产生一个复位脉冲。
这个复位脉冲一直有效，直到VCC降到1V以下。
如果V CC在降落到V TRIP后上升，超过V后延时约200ms，复位信号消失，使得微处理器可以继续工作。
则在V时内部的非易失性写周期已经初始化了，WP变为低电平不起作用。
4 VSS 地5 SI 串行输入：SI是串行数据输入端，指令码、地址、数据都通过这个引脚进行输入。
