Some ARM microcontrollers integrate many peripherals, such as Ethernet MAC, MMU, USART and so on, therefore less peripheral elements are needed. With this attribute, low cost, high reliability can be achieved in the ARM based control systems.

• 有些ARM控制器还集成了以太网MAC控制器、存储器管理单元MMU以及各种外围模块,可以运行操作系统,给底层设备入网提供了可行的解决方案。
