  • system power consumption to a minimum by selectively enabling/disabling the processor and various peripherals under software control. It uses an enhanced clock generator to provide a selection of clock signals including a slow clock (32 kHz) to optimize power consumption and performance at all times。

    The AT91RM9200 integrates a wide range of standard interfaces including USB 2.0 Full Speed Host and Device and Ethernet 10/100 Base-T Media Access Controller (MAC), which provides connection to a extensive range of external peripheral devices and a widely used networking layer. In addition, it provides an extensive set of peripherals that operate in accordance with several industry standards, such as those used in audio, telecom, Flash Card, infrared and Smart Card applications。

    To complete the offer, the AT91RM9200 benefits from the integration of a wide range of debug features including JTAG-ICE, a dedicated UART debug channel (DBGU) and an embedded real time trace. This enables the development and debug of all applications, especially those with real-time constraints。
