Extremely Accurate SPI Bus RTC with Integrated Crystal and SRAM

General Description The DS3234 is a low-cost, extremely accurate SPI bus real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The DS3234 incorporates a precision, temperature-compensated voltage reference and comparator circuit to monitor VCC. B

超高精度、SPI总线RTC，集成晶体和SRAM

DS3234是一款低成本、超高精度、采用SPI™总线的实时时钟(RTC)，集成了温度补偿晶体振荡器(TCXO)和晶体。DS3234内置经过温度补偿的精密电压基准和比较器电路用来监视VCC。当VCC跌落至低于电源失效电压(VPF)时，器件产生/RST输出；当VCC跌落至同时低于VPF和VBAT时，器件将禁止读/写访问。器件还对/RST引脚进行监视，可作为按钮输入以产生µP复位。当器件的主电源中断时，器件切换至备用电源输入以保持精确的计时。集成的晶体谐振器增强了器件的长期精度同时减少了生产线上的零件数量。DS3234提供商业级和工业级温度范围，并采用工业标准300mil、20引脚SO封装。\n\n • 在0°C至+40°C范围内，精度为±2ppm\n• 在-40°C至+85°C范围内，精度为±3.5ppm\n• 为不间断计时提供电池备份输入\n• 工作温度范围 \n• 商业级：0°C至+70°C \n• 工业级：-40°C至+85°C\n\n\n• 低功耗\n• 实时时钟计数秒、分、时、星期、日期、月份和年份信息，具有有效至2099年的闰年补偿\n• 提供每天两个定时闹钟\n• 可编程方波输出\n• 4MHz SPI接口，支持模式1和3\n• 数字温度传感器输出：精度为±3°C\n• 老化修正寄存器\n• /RST输入/输出\n• 300mil、20引脚SO封装;
