便携系统控制器

DS1673便携式系统控制器是一种将低功耗便携式产品所需的许多功能集成到一个芯片中的电路。该器件提供实时时钟(RTC)、NV RAM控制器、微处理器监控器和3通道、8位模数转换器(ADC)。通过简单的3线接口与DS1673建立通信。\n\n RTC提供秒、分、时、星期、日期、月和年信息以及闰年补偿。RTC还提供警报中断。当DS1673由系统电源供电或采用备用电池供电时，该中断起作用，因此该警报可用于唤醒关断的系统。\n\n 通过VCCO、低电平有效CEOL和低电平有效CEOH引脚提供外部SRAM的自动备份和写保护。用于为RTC供电的备用能源还用于在没有VCC的情况下通过VC • 提供实时时钟\n• 为秒、分、时、日期、\n\n• 月、星期和年计数，\n\n• 闰年补偿有效期至2100年\n\n• 电源控制电路支持系统\n\n• 通过星期/时间警报上电\n\n\n\n\n• 微处理器监控器\n• 在电源故障期间停止微处理器\n\n• 在电源故障之后\n\n• 自动重新启动微处理器\n\n• 监控按钮的外部覆盖情况\n\n• 停止并复位失控的\n\n• 微处理器\n\n\n\n\n• NV RAM控制\n• 对外部SRAM提供\n\n• 自动电池备份和写保护\n\n\n\n\n• 3通道、8位ADC\n\n• 简单的3线接口\n\n• +3.0V或+5.0V电源;
