ATSAMD11C14A-SSUT

Overview

The ATSAMD11C14A-SSUT is a low-power microcontroller from the Atmel SMART SAM D11 series, featuring a 32-bit ARM Cortex-M0+ processor operating at up to 48MHz. It integrates 16KB of in-system self-programmable Flash and 4KB of SRAM within a 14-pin SOIC package. The device includes a full-speed crystal-less USB 2.0 device interface, three Serial Communication Modules (SERCOM), a 12-bit ADC with up to 10 channels, and a Peripheral Touch Controller supporting capacitive touch interfaces.

Feature Summary

• Supports SleepWalking peripherals to wake from standby based on predefined conditions while keeping the CPU stopped.
• Includes an Event System for synchronous and asynchronous inter-peripheral signaling without CPU intervention.
• Features a 12-bit ADC with hardware oversampling and decimation to support resolutions up to 16 bits.

Applications

• Capacitive touch user interfaces such as buttons, sliders, and wheels
• Low-power embedded devices requiring crystal-less USB connectivity
• Simple control applications utilizing Timer/Counter and TCC modules

Procurement Notes

Verify the ordering code matches the specific pin count and package type required for your design. Confirm that the suffix indicates the correct temperature range and carrier type. Ensure compatibility with existing firmware due to identical peripheral modules across the SAM D11 series. Check for any specific revision notices or packaging changes before finalizing procurement.

Selection Notes

Select this component for designs prioritizing low power consumption and simple migration paths within the SAM D family. It is suitable for applications needing basic analog-to-digital conversion and serial communication without complex processing requirements. Consider the limited I/O count if extensive peripheral connectivity is needed.

Part Context

This part belongs to the Atmel SMART SAM D11 series of microcontrollers. The series is designed for intuitive migration with identical peripheral modules and hex-compatible code across different pin counts. It supports easy upgrades to larger devices within the SAM D family while maintaining pin compatibility.
