1024-Bit, 1-Wire EEPROM for Automotive Applications

General Description The DS2431 is a 1024-bit, 1-Wire® EEPROM chip organized as four memory pages of 256 bits each. Data is written to an 8-byte scratchpad, verified, and then copied to the EEPROM memory. As a special feature, the four memory pages can individually be write protected or put in E

1024-Bit, 1-Wire EEPROM for Automotive Applications

General Description The DS2431-A1 is an AEC-Q100 Grade 1 qualified version of the DS2431. The logical behavior of both versions is identical. The DS2431-A1 is a 1024-bit, 1-Wire® EEPROM chip organized as four memory pages of 256 bits each. Data is written to an 8-byte scratchpad, verified, a

适用于汽车应用的1024位、1-Wire EEPROM

DS2431-A1是DS2431的AEC-Q100 1级认证版本。两个版本的逻辑行为相同。DS2431-A1是一款1024位1-Wire® EEPROM芯片，其结构为四个存储器页，每页为256位。数据被写入8字节暂存区，经过验证，然后复制到EEPROM存储器。作为一个特殊特性，四个存储器页可以单独进行写保护或置于EPROM仿真模式，其中的位只能从1更改为0状态。DS2431-A1通过单导线1-Wire总线进行通信。通信遵循标准1-Wire协议。每个器件都有自己的唯一64位ROM注册编码，该注册编码不可更改且出厂时已印刻到芯片中。注册编码用于在多点1-Wire网络环境中对器件进行寻址。\n\n • 1024位EEPROM存储器分为四页，每页256位\n\n• 单个存储器页可以受到永久写保护或置于EPROM仿真模式（“写入0”）\n\n• 开关点迟滞和滤波可优化存在噪声时的性能\n\n• IEC 1000-4-2 4级ESD保护（+8kV接触放电，+15kV空气放电，典型值）\n\n• 在4.5V至5.25V电压范围内读取和写入（-40°C至+125°C）\n\n• 使用1-Wire协议通过15.4kbps的单个数字信号与主机进行通信\n\n• 符合AEC-Q100 1级认证要求\n\n• 还提供工业温度范围的标准版本(DS2431);
