The SMART SAM D11 is a series of low-power microcontrollers using the 32-bit ARM Cortex -M0+ processor, and ranging from 14- to 24-pins with 16KB Flash and 4KB of SRAM. The SAM D11 devices operate at a maximum frequency of 48MHz and reach 2.46 Coremark/MHz They are designed for simple and intuitive migration with identical peripheral modules, hex compatible code, identical linear address map and pin compatible migration paths between all devices in the product series. All devices include intelligent and flexible peripherals, Event System for inter-peripheral signaling, and support for capacitive touch button, slider and wheel user interfaces. The SAM D11 series is compatible to the other product series in the SAM D family, enabling easy migration to larger device with added features. All devices have accurate and low-power external and internal oscillators. All oscillators can be used as a source for the system clock. Different clock domains can be independently configured to run at different frequencies, enabling power saving by running each peripheral at its optimal clock frequency, and thus maintaining a high CPU frequency while reducing power consumption. The SAM D11 devices have two software-selectable sleep modes, idle and standby. In idle mode the CPU is stopped while all other functions can be kept running. In standby all clocks and functions are stopped expect those selected to continue running. The device supports SleepWalking. This feature allows the peripheral to wake up from sleep based on predefined conditions, and thus allows the CPU to wake up only needed, e.g. a threshold is crossed or a result is ready. The Event System supports synchronous and asynchronous events, allowing peripherals to receive, react to and send events even in standby mode. The Flash program memory can be reprogrammed in-system through the SWD interface. The same interface can be used for non-intrusive on-chip debug and trace of application code. A boot loader running in the device can use any communication interface to download and upgrade the application program in the Flash memory.
