SMART ARM-Based Microcontrollers SAM D20E / SAM D20G / SAM D20J
DATASHEET COMPLETE Introduction
В® в„ў Atmel | SMART SAM D20 is a series of low-power microcontrollers using
В®
В®
the 32-bit ARM Cortex -M0+ processor, and ranging from 32-to 64-pins
with up to 256KB Flash and 32KB of SRAM. The SAM D20 devices operate
В®
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, Atmel Event System for
inter-peripheral signaling, and support for capacitive touch button, slider and
wheel user interfaces. Features Processor
– ARM Cortex-M0+ CPU running at up to 48MHz Single-cycle hardware multiplier
Memories
– 16/32/64/128/256KB in-system self-programmable Flash
– 2/4/8/16/32KB SRAM Memory
System
– Power-on reset (POR) and brown-out detection (BOD)
– Internal and external clock options with 48MHz Digital Frequency
Locked Loop (DFLL48M) …
