SAM DA1
32-bit ARM-Based Microcontrollers
Introduction
В® В® The SAM DA1 is a series of low-power microcontrollers using the 32-bit ARM Cortex -M0+ processor,
and ranging from 32-to 64-pins with up to 64KB Flash, 8KB of SRAM and up to 2KB Read-While-Write
(RWW) Flash section. The SAM DA1 operate at a maximum frequency of 48MHz and reach 2.46
В®
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. Features Processor
