Overview

The ATSAMD11C14A-SSUT is a low-pin-count, entry-level ARM Cortex-M0+ microcontroller designed for simple USB-to-serial bridges and small footprint embedded control. Operating at 48MHz with 16KB of Flash and 4KB of RAM, it features a crystal-less USB 2.0 interface that simplifies BOM costs in compact designs. Its wide operating voltage of 1.62V to 3.63V makes it ideal for battery-powered applications and modern low-voltage systems.

Why Choose This Part

The primary advantage is the crystal-less USB operation, which saves PCB space and reduces component count. It also features a flexible Event System and 6-channel DMA that allow peripherals to communicate without CPU intervention, significantly reducing power consumption and improving real-time responsiveness.

Applications

USB-to-UART Bridges
Utilizing the crystal-less USB 2.0 Full-Speed interface to create compact serial converters for debugging or peripheral communication.
Human Interface Devices (HID)
Implementing small-form-factor USB mice, keyboards, or custom control surfaces using the Peripheral Touch Controller (PTC).
Smart Battery Management
Monitoring cell health and communicating status over I2C or USB in space-constrained battery packs.
Industrial Sensor Nodes
Collecting analog data via the 12-bit ADC and transmitting over LIN bus or SPI in industrial automation environments.

Getting Started

Developers can begin evaluation with the SAM D11 Xplained Pro evaluation kit. Development is supported by the Microchip Studio (formerly Atmel Studio) and MPLAB X IDEs, utilizing the Atmel Software Framework (ASF) or MPLAB Harmony for driver configuration. Debugging is handled via the Serial Wire Debug (SWD) interface using tools like the Atmel-ICE or PICkit 4.
