Versatile ARM-based microcontrollers target host of applications

The devices integrate high-precision 12-bit analogue and internal oscillators, two 16-bit timer/counters, one timer/counter for control applications, real-time performance, and flexible clocking options and sleep modes.

The devices include a 6-channel DMA controller supporting both memory and peripheral data transfers. The SAM D10D and D11D devices also include three (two in the SAM D11C) serial communication modules (SERCOM) that can be configured from the application to act as an USART, UART, SPI, and I²C interface.        

The SAM D11 also includes a Full-Speed USB 2.0 Device interface. Both devices incorporate the Atmel QTouch Peripheral Touch Controller, which offers built-in hardware support for buttons, sliders, wheels and proximity, and supports both mutual- and self-capacitive touch without the need for external components. The devices also feature power-saving techniques, including an event system that allows peripherals to communicate directly with each other without involving the CPU.      

The microcontrollers provide in-system programmable Flash, six-channel direct memory access (DMA) controller, programmable interrupt controller, and up to 22 programmable I/O pins. The devices are supported by a full suite of program and system development tools, including C compilers, macro assemblers, program debugger/simulators, programmers and evaluation kits.
