ATSAMD11D14A-SSUT

Overview

The ATSAMD11D14A-SSUT is a 32-bit microcontroller from the SAM D11 series, utilizing an ARM Cortex-M0+ processor. It features 16KB of in-system self-programmable Flash and 4KB of SRAM. The device operates at a maximum frequency of 48MHz and supports an operating voltage range of 1.62V to 3.63V. It includes a full-speed USB 2.0 interface, up to three SERCOM modules, a 12-bit ADC with 10 channels, and a 10-bit DAC. The component is housed in a 20-pin SOIC package.

Feature Summary

• ARM Cortex-M0+ processor running at up to 48MHz
• Full-speed crystal-less USB 2.0 device interface
• Capacitive touch sensing support via Peripheral Touch Controller
• Integrated analog peripherals including ADC, DAC, and comparators

Applications

• Low-cost consumer electronics requiring USB connectivity
• Simple sensor interfaces using serial communication protocols
• Battery-powered devices utilizing low-power sleep modes
• Basic human-machine interfaces with capacitive touch controls

Procurement Notes

Verify the specific ordering suffix 'U' indicates the -40°C to 85°C temperature grade and 'T' denotes tape and reel packaging. Confirm that the manufacturer designation has transitioned from Atmel to Microchip Technology for accurate sourcing and documentation alignment. Ensure compatibility with existing design files before procurement.

Selection Notes

Select this model for applications requiring a balance of processing capability and peripheral integration within a compact 20-pin form factor. The device is suitable for designs needing direct USB connectivity without external transceivers. Consider the pin count limitations regarding available I/O and analog channels when defining system requirements.

Part Context

This component belongs to the SAM D11 family of microcontrollers designed for easy migration between different pin counts and memory densities. It shares identical peripheral modules and code compatibility with other devices in the series, such as the 14-pin and 24-pin variants. This allows for flexible product line scaling while maintaining software consistency across the platform.

Replacement Considerations

ATSAMD11D14A-SSNT: Identical specifications but supplied in tube packaging instead of tape and reel.
