Overview

The ATSAMD11D14A-MU is a compact, 32-bit ARM Cortex-M0+ microcontroller designed for power-sensitive and space-constrained applications. Operating at up to 48MHz with 16KB of Flash and 4KB of SRAM, it features a Full-Speed USB 2.0 device interface and a flexible Event System that allows peripherals to communicate without CPU intervention.

Why Choose This Part

The device features the Atmel Event System and SleepWalking technology, which allow for autonomous peripheral operation during standby modes to drastically reduce power consumption. Its small 4x4mm QFN24 package includes a 12-bit ADC and 10-bit DAC, providing significant analog capability in a footprint smaller than many 8-bit alternatives.

Applications

USB-to-Serial Bridges
Utilizing the integrated Full-Speed USB device controller and three SERCOM modules to create compact, low-cost interface converters.
Battery-Powered Sensor Nodes
Leveraging SleepWalking technology and 1.62V to 3.63V operation to minimize power consumption in remote monitoring devices.
Internal System Controllers
Serving as a dedicated co-processor for power sequencing, fan control, or HID input management in larger embedded systems.

Getting Started

Development is primarily supported through the SAM D11 Xplained Pro evaluation kit (ATSAMD11-XPRO) and the Microchip Studio or MPLAB X IDEs. Engineers can use the Atmel Software Framework (ASF) or MPLAB Harmony for driver configuration, while the device is programmed and debugged via the standard SWD interface.
