ARM Cortex-M0+ Processor
The most energy-efficient ARM processor yet, the Cortex-M0+
builds on the Cortex-M0 processor—retaining its full instruction set
and tool compatibility—while further reducing energy consumption
and increasing performance. SAM D ARM Cortex-M0+ based
MCUs operate at 48MHz and feature a two-stage pipeline,
single-cycle I/O access, single-cycle 32x32 multiplier, event
system, and a fast and flexible interrupt controller. Highly efficient,
the Atmel SAM D family reaches 2.14 CoreMark/MHz – 0.93
DMIPS/MHz.

The Atmel SAM D family of ARM
Cortex-M0+ based microcontrollers (MCU)
leverages two decades of experience. It builds
on the success of our popular Atmel AVR MCUs
and ARM-based devices. The Atmel SAM D
family delivers a powerful combination of proven
technologies—such as our peripheral event
system—as well as the latest Atmel innovations,
including capacitive touch support for buttons,
sliders, wheels and proximity. This truly
differentiated general-purpose microcontroller is
a perfect fit for many low-power, cost-sensitive
industrial and consumer applications.

Easy Migration
Made with portability in mind, these devices are code-compatible
so that you can easily move between both memory densities and
pinouts. Plus, the different pin options are designed to minimize
PCB changes when going from one pin count to another. With the
TQFP package, you can even lay out the three different packages
inside each other.
