ATSAMD10D13A-SSNT

Overview

The ATSAMD10D13A-SSNT is an ARM Cortex-M0+ microcontroller in a 20-pin SOIC package. It features 8 KB of Flash memory and 4 KB of SRAM, operating at a maximum frequency of 48 MHz with a supply voltage range of 1.62 V to 3.63 V. The device includes up to 22 programmable I/O pins, a 12-bit ADC with 10 channels, a 10-bit DAC, two analog comparators, and three SERCOM interfaces supporting SPI, I2C, UART, and USART protocols.

Feature Summary

• Integrates a 32-bit ARM Cortex-M0+ processor with single-cycle hardware multiplier and Micro Trace Buffer for efficient code execution.
• Includes intelligent peripherals such as a six-channel DMA controller, six-channel Event System, and Peripheral Touch Controller for capacitive sensing.
• Supports low-power operation through idle and standby sleep modes, SleepWalking capabilities, and independent clock domain configuration.
• Provides flexible serial communication via three SERCOM modules configurable as USART, UART, SPI, I2C, SMBus, PMBus, or LIN slave.

Applications

• Low-cost consumer electronics requiring simple embedded control
• Battery-powered devices utilizing low-power sleep modes
• Industrial control systems using event-driven peripheral signaling
• Wearable technology incorporating capacitive touch interfaces

Procurement Notes

Verify the ordering suffix SSNT indicates tape and reel packaging and industrial temperature grade (-40°C to +105°C). Confirm the 'A' variant matches the required functional specification. Ensure compatibility with standard SOIC-20 footprint dimensions and soldering profiles specified in the datasheet thermal considerations section.

Selection Notes

Select this part when 8 KB of program memory suffices for the application logic. Choose the 20-pin SOIC package if board space allows larger footprints compared to QFN or WLCSP options. Verify that the 10 available ADC channels meet signal acquisition requirements before considering variants with higher channel counts.

Part Context

This component belongs to the SAM D10 series, designed for intuitive migration within the SAM D family. It shares identical peripheral modules and linear address maps with other series members, facilitating hex-compatible code reuse. The device supports pin-compatible upgrades to larger microcontrollers with increased memory and I/O capacity.

Replacement Considerations

ATSAMD10D13A-SSUT: Identical electrical specifications but supplied in tape and reel packaging instead of cut tape.

FAQ

How does the SAM D10 achieve power savings during operation?

The device supports idle and standby sleep modes. In standby mode, clocks and functions stop except those selected to continue running. The SleepWalking feature allows peripherals to wake the CPU based on predefined conditions.

What clock sources are available for the system clock?

All devices have accurate external and internal oscillators, including a 32.768 kHz crystal oscillator, a 0.4-32 MHz crystal oscillator, and internal oscillators like OSC8M and OSCULP32K. These can feed the DFLL48M or FDPLL96M.

Can the Timer/Counters be cascaded?

Yes, specific TCs can be cascaded to form a 32-bit Timer/Counter. They can operate in 8-bit or 16-bit mode and support frequency generation, waveform output, and input capture.
