【应用】24MHz频率的晶科鑫晶振7U24000E12UCG用于主控MCU外挂,最大只有±10ppm的频率漂移
MCU有各种各样的外设为了能有条不紊的稳定运行,都离不开统一的时钟。晶振震荡频率是MCU的脉搏,CPU在与定时器和看门狗、UART收发器、I²C总线、SPI总线、GPIO、ADC、SW-DP调试端口、温度传感器等通信,执行指令、访问数据、DMA搬运、状态变换等动作都离不开晶振,串口数据收发、A/D转换、定时器计数等外设工作也是在晶振的驱动下完成的。
往往MCU会搭配一颗外部晶振来确保芯片整体稳定的运行并且软件时序不出问题,高速外部晶振可以使用一个2~24MHz的晶体/陶瓷谐振器构成的振荡器产生,布线时谐振器和负载电容必须尽可能地靠近振荡器的引脚,以减小输出失真和启动时的稳定时间。
晶科鑫7U24000E12UCG采用常用的3225封装,封装较典型,外围搭配12PF匹配电容,下图为晶科鑫7U24000E12UCG的外部尺寸图:

综上晶科鑫7U24000E12UCG用于MCU外挂高速晶振,具有如下优势:
1、晶科鑫7U24000E12UCG在25℃时最大只有±10ppm的频率漂移,频率精度较高,使主芯片很稳定工作,并可以防止频率被干扰;
2、晶科鑫7U24000E12UCG外围搭配的匹配电容容值为12PF,是较为通用的匹配值,方便器件选型;
3、晶科鑫7U24000E12UCG工作温度范围为-40~85°C,能很好的适应芯片工作时的微量发热,且从-40~85℃最大只有±30ppm的频率漂移,温漂也十分稳定;
4、晶科鑫7U24000E12UCG采用较典型的SMD3225封装,封装较小,且较为典型,是通用的晶振焊盘封装,有利于开发的简单化。
综上所述,晶科鑫7U24000E12UCG高速外部晶振适合用于MCU外挂。
