ATSAML10D16A-YFT

Overview

The ATSAML10D16A-YFT is a 32-bit microcontroller from the SAM L10 family, featuring an ARM Cortex-M23 core operating at a maximum frequency of 32 MHz. It integrates 64 KB of Flash memory and 16 KB of SRAM. The device supports a supply voltage range of 1.62 V to 3.63 V and operates within a temperature range of -40°C to +85°C. It is housed in a 24-SSOP package and includes peripherals such as I2C, SPI, UART/USART, LINbus, DMA, PWM, and watchdog timers.

Feature Summary

• Ultra-low power consumption with active mode current below 25 uA/MHz and sleep mode current under 100 nA
• Integrated cryptographic security features for data protection
• Supports multiple communication interfaces including I2C, SPI, UART/USART, and LINbus
• Includes analog peripherals such as ADC, DAC, operational amplifiers, and analog comparators

Applications

• Battery-powered wearable devices requiring extended standby life
• Smart home sensors and actuators with low power constraints
• Industrial monitoring nodes utilizing LINbus or serial communication

Procurement Notes

Verify the specific suffix YFT confirms the 24-SSOP package and industrial temperature grade. Confirm RoHS compliance status through official Microchip documentation. Ensure compatibility with existing PCB footprints for SSOP-24 components. Check for any recent Product Change Notifications regarding assembly sites or packaging updates before finalizing procurement plans.

Selection Notes

Select this component when ultra-low power performance is critical alongside moderate code storage requirements. The 64 KB Flash and 16 KB RAM balance capacity with energy efficiency. Consider the 24-SSOP package if leadless packages are not feasible. Verify that the required peripheral count, specifically the number of SERCOMs and analog channels, meets application needs without exceeding available pins.

Part Context

This MCU belongs to the SAM L10 family, designed for cost-sensitive and power-constrained applications. It shares architectural similarities with the SAM L11 series but typically lacks certain high-end security or connectivity features found in higher-tier models. The family targets simple control tasks where minimal active current is paramount.

Replacement Considerations

Direct substitutes within the same package include ATSAML10D16A-MUT (VQFN) if form factor changes are acceptable. For identical pinout and functionality, verify cross-referencing with ATSAML10E15A-UUT, noting differences in Flash/RAM size and package type. Always consult the latest datasheet errata for functional nuances between variants.
