Think Beyond the Core Introducing Microchip SAM D20 ARM-based Microcontrollers

Bringing AVR^® Ease-of-Use to Cortex^® M0+ MCUs

Microchip SAM D20

The Microchip SAM D20 family—based on the ARM^® Cortex^®- M0+ core—builds on decades of innovation and experience in embedded Flash microcontroller (MCU) technology. It not only sets a new benchmark for flexibility and ease-of-use but also combines the performance and energy efficiency of the ARM^® Cortex^®-M0+ core with an optimized architecture and peripheral set. This truly differentiated general-purpose MCU family is ideal for many low-power, cost-sensitive industrial and consumer applications.

Key Features

Low Power - Market-leading power-saving techniques include an event system that allows peripherals to communicate directly with each other without involving the CPU. Microchip SleepWalking™ peripherals also wake up the CPU only upon a pre-qualified event, reducing overall power consumption.
Peripheral Flexibility - An innovative serial communication module (SERCOM) is fully software-configurable to handle I2C, USART/UART and SPI communications. With multiple SERCOM modules on a device, you can tailor the peripheral mix precisely to your application.
Microchip QTouch® Peripheral Touch Controller - Offers built-in hardware support for buttons, sliders, wheels and proximity, and supports both mutual and self-capacitive touch without the need for external components. It offers superb sensitivity and noise tolerance, as well as self-calibration, making any user tuning superfluous.
Scalability - Flash memory densities range from 16KB to 256KB and devices are available in 32-, 48- and 64-pin QFP and QFN package options, with BGA and WLCSP package options to be added.

Getting Started with the SAM D20 Family

The Microchip SAM D20 Xplained Pro board is the ideal platform for evaluation and prototyping with the SAM D20 microcontroller (MCU). The board gives access to all IO pins as well as some buttons and LEDs and offers expansion possibilities with its multiple extension ports. Code can easily be moved from the SAM D20 Xplained Pro to your target device, as the SAM D20 devices are binary-compatible.

Three Device Families for a Broad Range of Design Needs

The Microchip SAM D20 series is designed for easy migration within the Microchip MCU portfolio. Devices are compatible across pinouts for drop-in replacement and are code-compatible with upcoming series that introduce additional features. If you need more performance or larger Flash memory, the Microchip SAM4L based on the ARM^® Cortex^®-M4 core is upwards compatible with the Microchip SAM D20.
