Overview

The ATSAMD11D14A-MUT is a low-power, entry-level 32-bit microcontroller featuring an ARM Cortex-M0+ core running up to 48MHz. It is specifically designed for cost-sensitive applications requiring crystal-less USB connectivity and integrated analog peripherals in a compact 24-pin QFN package.

Why Choose This Part

This MCU provides a highly integrated solution with 16KB Flash and 4KB RAM, including a Full-Speed USB controller that operates without an external crystal. The inclusion of a 10-bit DAC and 10 channels of 12-bit ADC allows for sophisticated analog signal processing in a tiny 4x4mm footprint.

Applications

USB Peripheral Bridges
Acts as a cost-effective USB-to-UART or USB-to-I2C bridge for interfacing legacy sensors or peripherals with a PC host.
Battery-Powered Consumer Devices
Utilizes SleepWalking and low-power modes to extend battery life in handheld devices and portable electronics.
HID Input Devices
Ideal for small-form-factor keyboards, mice, or custom control surfaces requiring Full-Speed USB without external crystals.
Embedded System Controllers
Serves as a dedicated sub-processor for power management, house-keeping, or sensor data aggregation in larger systems.
