ATSAMD11D14A-SSNT

Overview

The ATSAMD11D14A-SSNT 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 memory and 4KB of SRAM. The device operates at a maximum frequency of 48MHz with a supply voltage range of 1.62V to 3.63V. It includes a full-speed USB 2.0 interface, up to three SERCOMs, a 12-bit ADC, and a 10-bit DAC. The component is housed in a 20-pin SOIC package.

Feature Summary

• Supports low-power operation with idle and standby sleep modes and SleepWalking peripherals.
• Integrates a six-channel Direct Memory Access Controller for efficient data transfer.
• Provides flexible serial communication via configurable Serial Communication Modules.
• Includes a Peripheral Touch Controller for capacitive touch sensing applications.

Applications

• Simple migration projects requiring identical peripheral modules and pin-compatible paths.
• Applications utilizing capacitive touch button, slider, or wheel user interfaces.
• Systems requiring a full-speed crystal-less USB 2.0 device interface.
• Low-power embedded designs needing independent clock domain configuration.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with required manufacturing standards such as RoHS. Confirm that the tape and reel carrier type matches assembly line specifications. Cross-reference the manufacturer product number with current datasheets to validate revision status before procurement.

Selection Notes

Select this model when a 20-pin SOIC package is required within the SAM D11 family. It provides the same core performance and memory as other variants but differs in physical footprint. Consider the 24-pin QFN or 14-pin SOIC options if different I/O counts or package sizes are needed. Verify that the 22 programmable I/O pins meet the design requirements.

Part Context

This component belongs to the Atmel SMART SAM D11 series of low-power microcontrollers. The series is designed for intuitive migration with identical linear address maps and hex-compatible code across devices. It supports easy upgrades to larger devices within the SAM D family while maintaining peripheral module consistency.
