ATSAMD10D13A-MUT

Overview

The ATSAMD10D13A-MUT is a 32-bit microcontroller from the SAM D10 series, utilizing an ARM Cortex-M0+ processor. It features 8KB of in-system 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 12-bit ADC with 10 channels, a 10-bit DAC, two analog comparators, and a Peripheral Touch Controller. Connectivity options include up to three SERCOM modules supporting USART, SPI, I2C, and LIN slave protocols. The component is housed in a 24-pin QFN package.

Feature Summary

• Supports capacitive touch sensing via the Peripheral Touch Controller for buttons, sliders, and wheels.
• Enables low-power operation through idle and standby sleep modes with SleepWalking peripheral wake-up capabilities.
• Provides flexible inter-peripheral signaling using a six-channel Event System that functions independently of the CPU.
• Allows in-system programming and non-intrusive debugging via the Serial Wire Debug (SWD) interface.

Applications

• Simple user interfaces requiring capacitive touch input
• Low-power battery-operated devices
• General-purpose serial communication applications

Procurement Notes

Verify the specific ordering code against official Microchip documentation to ensure correct package type and temperature grade. Confirm that the required Flash density matches the 8KB variant. Check for any recent Product Change Notifications regarding assembly sites or material composition changes before finalizing procurement.

Selection Notes

Select this part when a compact 24-pin QFN form factor is required alongside 8KB of program memory. Ensure the application does not exceed the 48MHz clock speed limit. Verify that the available GPIO count meets the design requirements and that the operating voltage aligns with the 1.62V to 3.63V specification.

Part Context

This component belongs to the SAM D10 family of low-power microcontrollers based on the ARM Cortex-M0+ core. The series offers pin-compatible migration paths between different Flash densities and package types. It shares identical peripheral modules and address maps within the family, facilitating easy upgrades to larger devices without hardware redesign.

Replacement Considerations

ATSAMD10D14A-MUT provides 16KB Flash with identical pinout and peripherals.
