Cutting power
While maximizing performance, the SAM9M10 contains a number of advanced features that minimize power consumption and reduce the number of external components required. At 400MHz operation and a 1V core supply the typical power consumption less than 300W/MHz. In backup mode with the RTC running, the SAM9M10 only consumes around 8A. The system controller incorporates startup, shutdown and power-on reset controllers, on-chip oscillators for 12MHz and 32KHz, and a power management controller that fine-tunes power consumption to the required system performance under all conditions of use. I/Os have programmable slew rate to simplify PCB design and support 1.8V and 3.3V operation to eliminate external level shifters, thereby reducing component count and board area.

A bandwidth of 480Mbit/s high-speed USB can meet growing demands for bandwidth. The EHCI-compliant high-speed USB host provides a well-understood, easy-to-use vehicle to handle large amounts of data and interconnection between systems and the PCBs inside a system. The SAM9M10 USB host is fully compliant to the EHCI and OHCI standards that guarantee straightforward porting of proven USB host drivers to the SAM9M10. These features shorten the development cycle and secure higher quality standards.

The SAM9M10 is released with an evaluation kit and supported by a free Linux distribution and Microsoft Windows Embedded CE BSP, including a video driver and GStreamer and DirectShow multimedia frameworks, respectively.

Extensive documentation including a ready-to-run demonstration explaining how to use and customize the source code and how to build applications is also provided. The device is supported by the worldwide ecosystem of suppliers of development tools, OS, protocol stacks and applications that Atmel has built up around its AT91SAM family of ARM-based MCUs and embedded microprocessors including Mentor Graphics, Fluffy Spider Technology, QNX, Micrium, IAR, Keil, Segger, Adeneo and TimeSys.

The SAM9M10 is sampling now, and is priced at $11.40 in quantities of 10K units. The SAM9M10 evaluation kit is also available at $750 for single unit quantities.
