32-bit ARM-Based
Microcontrollers
SAM D21E / SAM D21G / SAM D21J
Introduction
® ® The SAM D21 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 256KB Flash and 32KB of SRAM. The SAM D21 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. Features
• • • • • Processor
– ARM Cortex-M0+ CPU running at up to 48MHz
• Single-cycle hardware multiplier
• Micro Trace Buffer (MTB)
Memories
– 32/64/128/256KB in-system self-programmable Flash
– 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)
and 48MHz to 96MHz Fractional Digital Phase Locked Loop (FDPLL96M) …
