Cortex.-M0内核，可用于工业控制和需要 高性能、低功耗的应用. Cortex.-M0是ARM最新的微处理器，有32位的性能，但是价格只相当于传 统的8位单片机. NuMicro MINI51.系列最快可以跑到24MHz. 因而可以支持很广范围的工业控制和需要高性能CPU 的场合. NuMicro MINI51. 系列内嵌4K/8K/16K字节程序flash，数据flash大小可配置(与程序flash共 享) ,2K字节ISP flash，2K字节SRAM. 为了降低成本，减小空间，NuMicro MINI51. 系列内嵌了很多外设，像：I/O口、定时器、UART、 SPI、I2C、PWM、ADC、看门狗和低电压检测，这使NuMicro MINI51. 系列可以用于更广泛的应 用. 另外，NuMicro MINI51. 系列还配备ISP (In-System Programming) 和 ICP (In-Circuit Programming) 功能，让用户可以升级固件而不必将芯片从板子上取下. 2 特性 .. 内核 ..
