At Embedded World in Nuremberg, Atmel introduced the SAM D10, SAM D11 and SAM D21 series of embedded Flash microcontrollers (MCU), expanding the Atmel® ARM® Cortex®-M0+ based SAM D family from the 15 SAM D20 devices shipping in volume now to a total of 39 devices. With this new range of lower-end ARM Cortex based devices Atmel will have a complete MCU offering, including the best 8-bit products available as well as a Cortex-M0+ family that sets a new benchmark for flexibility, functionality, compatibility and ease of use.
In addition to new pinout and memory options, the three new series introduce additional functionality on top of the SAM D20 series unique Event System, SERCOM module, and Peripheral Touch Controller. Among the added functionality is Full Speed USB 2.0 device and embedded host, DMA, I2S, Timers/Counters for Control applications, increased I2C speed with support for SMBus and PMBus, UART with autobaud and IrDA support, and Micro Trace Buffer for easy debugging. The USB device can run from the internal RC Oscillator, simplifying design and reducing external circuitry. All SAM D devices are code- and pin-compatible, making it easy to migrate both up and down the family.
The SAM D21 series will be available in 32-, 48-, and 64-pin QFN and TQFP packages and will range from 32KB to 256KB of Flash. The SAM D21 series devices are pin-compatible with the SAM D20, while adding all the new features listed above.
The SAM D11 series will be available in 14- and 20-pin SOIC and 24-pin QFN packages and will be available with 8KB and 16KB of Flash. Both memory options will feature 4KB of SRAM. The SAM D11 series includes all the features listed above except the USB embedded host. The SAM 10 series is identical to the SAM D11 series, but does not feature a USB device.
The three new SAM D series extend the Atmel ARM Cortex based MCU portfolio—closing the gap between the Atmel megaAVR® and AVR® XMEGA® and the SAM3 and SAM4 products—and expanding Atmel’s addressable market. SAM D family features include:

The largest memory density for all pin-outs and packages of the SAM D21 devices will be open for sampling Feb 26th. The SAM D21 will start shipping to mass production in May.
SAM D10 and SAM D11 samples will be available towards the end of Q2. The SAM D10 and SAM D11 will start shipping to mass production in October.
All products available now are -40-85°C. 105°C versions will be introduced towards the end of 2014.
The SAM D21 Xplained Pro is available now. The Xplained Pro boards include an embedded debugger and programmer and have a wide range of compatible extensions. If you prefer to use a standalone programmer debugger, the Atmel SAM-ICE™ product fully supports the SAM D family. SAM D products are fully supported by Atmel Studio and Atmel Software Framework.
