ATSAMD10D14A-SSNT

Overview

The ATSAMD10D14A-SSNT is a 32-bit microcontroller from the SAM D10 series, utilizing an ARM Cortex-M0+ processor core. It features 16KB of in-system programmable Flash memory and 4KB of SRAM. The device operates at a maximum frequency of 48MHz and supports a supply voltage range of 1.62V to 3.63V. It is housed in a 20-pin SOIC package with an industrial temperature rating of -40°C to +85°C.

Feature Summary

• Includes intelligent peripherals such as a six-channel DMA controller and a six-channel Event System for inter-peripheral signaling without CPU intervention.
• Supports capacitive touch user interfaces via the Peripheral Touch Controller, enabling button, slider, wheel, and proximity sensing applications.
• Provides flexible serial communication options through up to three SERCOM modules configurable as USART, SPI, I2C, SMBus, PMBus, or LIN slave.
• Features low-power operation with idle and standby sleep modes, alongside SleepWalking capabilities that allow peripherals to wake the CPU based on predefined conditions.

Applications

• Smart home automation devices requiring low power consumption and simple control logic
• Consumer electronics with capacitive touch interface requirements
• Industrial smart metering systems needing reliable serial communication protocols
• Battery-powered wearable devices utilizing efficient sleep modes

Procurement Notes

Verify the specific ordering suffix 'SS' confirms the 20-pin SOIC package type and 'N' indicates tape and reel carrier format. Confirm the 'U' suffix corresponds to the -40°C to +85°C operating temperature range. Ensure compatibility with standard surface mount assembly processes for SOIC packages. Check for any recent Product Change Notifications regarding pinout or electrical characteristics updates.

Selection Notes

Select this component when a balance of moderate Flash capacity and extensive peripheral connectivity is required within a compact 20-pin form factor. Consider migration paths within the SAM D family if future upgrades to higher pin counts or additional memory are anticipated. Evaluate the need for the Peripheral Touch Controller if user interaction via touch is planned. Compare against other SAM D series members for identical peripheral module compatibility.

Part Context

This part belongs to the Atmel SMART SAM D10 series of low-power microcontrollers based on the ARM Cortex-M0+ architecture. The series is designed for intuitive migration with identical peripheral modules and linear address maps across different pin counts and memory densities. It serves as a foundational platform for embedded applications requiring efficient processing and versatile connectivity options.

Replacement Considerations

ATSAMD10D14A-SSUT: Same functional specifications but packaged in Tape & Reel instead of Cut Tape (if applicable). ATSAMD10D13A-SSNT: Identical package and carrier but with 8KB Flash memory instead of 16KB. ATSAMD10D14A-MNT: Same electrical specifications but housed in a 24-pin QFN package requiring PCB layout adjustments.

FAQ

How does the Event System enhance performance in the ATSAMD10D14A-SSNT?

The six-channel Event System allows peripherals to react to and send events synchronously or asynchronously without CPU intervention, reducing power consumption and improving response times.

What clock sources are available for the system clock?

The device supports internal and external oscillators, including a 48MHz Digital Frequency Locked Loop (DFLL48M) and a 48MHz to 96MHz Fractional Digital Phase Locked Loop (FDPLL96M).

Can the Timer/Counters be cascaded for higher resolution?

Yes, selected Timer/Counters (TCs) can be cascaded to form a 32-bit TC, providing enhanced timing and measurement capabilities for digital signals.
