MICROCHIP晶振MCP7940N系列低功耗实时时钟 (RTC) 使用数字时序补偿来实现精确的时钟/日历、可编程输出控制以实现多功能性,以及自动切换到备用电源的电源检测电路。它使用低成本的32.768kHz晶振,使用多个内部寄存器跟踪时间。对于通信,MCP7940N使用I2C™ 总线。时钟/日历自动调整少于31天的月份,包括闰年校正。时钟以24小时制或12小时制运行,带有 AM/PM 指示器和可设置为秒、分、小时、星期几、日期或月份的闹钟。使用可编程CLKOUT,可以从外部晶振产生32.768k、8.192k和4.096kHz和1Hz的频率。

MICROCHIP晶振MCP7940N系列低功耗实时时钟,MCP7940NT-ESTVAO,32.768k晶振

MCP7940N实时时钟/日历(RTCC) 使用内部计数器跟踪时间,包括小时、分钟, 秒、日、月、年和星期几。 可以在所有计数器上配置报警,最多可配置到和包括几个月。

开漏多功能输出可以是配置为在报警匹配时断言,输出一个可选频率方波,或作为一般目的输出。 

MCP7940N设计使用32.768k音叉晶体,带外部晶体负载电容。可以使用片内数字调整,为了调整由晶体引起的频率变化公差和温度。 

SRAM和计时电路由供电 主电源断电时的备用电源,允许 保持精确时间的装置和SRAM 内容。设备切换到的时间 备用电源和主电源恢复时 都由电源故障时间戳记录。
