【应用】集成USB接口的国产32位MCU用于手持式差压计,最高主频200M,工作电压2.6-3.6V
手持式差压计一般用于测量管道中流体的两点间压力差的仪器,有体积小、速度快、操作简单等特点。
下图是手持式差压计的原理框图,推荐采用国产雅特力32位MCU AT32F403ZET67为主控, 该MCU最高主频200M,Flash 512k, 工作温度范围-40至+85度,2.6至3.6V的工作电压,也被广泛应用于无人机,充电桩以及变频器等设备。
AT32F403ZET6应用于手持式差压计有如下优势:
1.AT32F403ZET6具备高性能Cortex-M4F内核,最高200M的主频,内置浮点运算FPU,以及DSP指令集,为用户提供高效的指令集控制。
2.该MCU集成有多种通信接口,包括UART,SPI,I2C,以及CAN接口,例如与差压传感器通信时,用到的I2C,SPI接口,MCU内置的接口即可满足与外设传感器的通信需求,无需外扩,使硬件设计更加简洁方便,也可有效降低成本。
3.还集成有USB2.0全速设备接口,遵循全速USB设备(12Mb/s)标准,端点可由软件配置,同时,具有待机、唤醒功能,与外设通信时,无需外加USB接口芯片,节省成本。
4.集成有3个21通道的12位ADC,可以实现对外部信号的快速,精准采样,无需外置ADC,便硬件设计,更简洁,也可有效提高产品的可靠性,稳定性。
5.他带有112个多功能双向的I/O口,所有I/O口可以映像到16个外部中断,使MCU可更快的响应外部事件,并且几乎所有IO可容忍5V电压输入,省去了额外的LDO,降低了成本。
6.还能提供睡眠、停机、和待机三种低功耗模式,在停机模式下,典型功耗可以做到1mA,可以有效延长电池的使用时间。
7.内置512K的Flash和96+128 K字节的SRAM,方便用户代码升级。
另外,AT32F403ZET6可替换STM32F429ZET6,国产MCU,供货有保障。
