ATSAML10D14A-MF

Overview

The ATSAML10D14A-MF is a 32-bit microcontroller from the Microchip SAM L10 series, featuring an ARM Cortex-M23 core. It integrates 16KB of flash memory and 2KB of EEPROM within a 24-VQFN package. The device operates on a supply voltage range of 1.62V to 3.63V with a maximum clock speed of 32MHz. It includes five 12-bit ADC channels and one 10-bit DAC. Connectivity options include I2C, LINbus, SPI, and UART/USART interfaces. The component supports peripherals such as DMA, PWM, and watchdog timers, functioning reliably in temperatures from -40°C to +85°C.

Feature Summary

• Integrates an ARM Cortex-M23 processor core for efficient 32-bit processing capabilities.
• Includes multiple analog-to-digital converters and a digital-to-analog converter for signal interfacing.
• Supports standard communication protocols including I2C, SPI, UART, and LINbus.
• Features integrated power management peripherals like brown-out detection and power-on reset.

Applications

• Low-power sensor nodes requiring minimal active current consumption
• Simple industrial control devices utilizing LINbus or UART interfaces
• Battery-operated consumer electronics needing extended standby times
• Basic data logging applications with limited memory requirements

Procurement Notes

Verify the specific suffix 'MF' indicates tray packaging when ordering, distinct from the 'MUT' tape-and-reel variant. Confirm the operating temperature grade corresponds to the commercial range (-40°C to +85°C) required for your application environment. Ensure design compatibility with the 24-VQFN footprint and verify that the 1.62V minimum supply voltage aligns with your system's power rails. Cross-reference the latest datasheet for any errata or pinout clarifications before finalizing the schematic.

Selection Notes

Select this model when a compact 24-pin form factor is necessary alongside basic connectivity needs. It is suitable for designs where code size remains under 16KB and RAM usage is minimal. Consider this part if cost-sensitive applications require ARM Cortex-M23 efficiency without complex networking stacks. Evaluate the trade-off between the limited I/O count and the reduced package size against more capable but larger alternatives in the same family.

Part Context

This component belongs to the SAM L10 family, designed specifically for ultra-low-power performance using ARM Cortex-M23 technology. It targets applications demanding long battery life with fast wake-up times. The family shares architectural similarities with the SAM L11 series but differs in security features and peripheral sets. This specific variant provides a balance of processing power and peripheral integration for simple embedded tasks.

Replacement Considerations

The ATSAML10D14A-MUT serves as a functional equivalent with identical electrical specifications but utilizes tape-and-reel packaging instead of trays. Other members of the SAM L10 family, such as those with higher flash capacities, may require software adjustments due to differing memory maps. Verify pin compatibility when substituting with variants offering different I/O counts or package types.
