ATSAML10D14A-YU

Overview

The ATSAML10D14A-YU is a 32-bit microcontroller from the SAM L10 series, featuring an ARM Cortex-M23 core operating at a maximum frequency of 32MHz. It integrates 16KB of Flash program memory and includes 2KB of EEPROM. The device operates within a supply voltage range of 1.62V to 3.63V and supports an industrial temperature range of -40°C to +85°C. Connectivity options include I2C, LINbus, SPI, and UART/USART interfaces. It is housed in a 24-SSOP package with 17 available I/O lines.

Feature Summary

• Integrates an ARM Cortex-M23 processor core for efficient 32-bit processing.
• Includes built-in analog peripherals such as five 12-bit ADC channels and one 10-bit DAC.
• Supports multiple communication protocols including I2C, SPI, UART, and LINbus.
• Features integrated power management capabilities like Brown-out Reset and Power-on Reset.

Applications

• Low-power embedded control systems
• Industrial sensor nodes
• Consumer electronics requiring compact form factors
• Battery-operated devices

Procurement Notes

Verify the package type matches the design requirements, as this specific model uses a 24-SSOP housing, which differs from the VQFN variant. Confirm the suffix 'YU' corresponds to the correct tape-and-reel or tube packaging configuration intended for assembly. Ensure compatibility with the target voltage domain, as the device requires a supply between 1.62V and 3.63V. Check for any recent Product Change Notifications regarding assembly sites or material composition updates.

Selection Notes

Select this component when a 32-bit architecture is required alongside a through-hole compatible SSOP package. It is suitable for designs needing moderate code storage with 16KB Flash and basic analog input capabilities via its ADC array. Consider this part if LINbus support is necessary for automotive or industrial bus networks. Evaluate pin count constraints, as the 24-pin limit restricts the number of available general-purpose I/Os compared to larger packages.

Part Context

This microcontroller belongs to the Microchip SAM L10 family, which is optimized for low-power applications using the Arm Cortex-M23 core. The family emphasizes energy efficiency while providing sufficient processing power for simple control tasks. The ATSAML10D14A-YU represents a specific memory and package configuration within this broader ecosystem, sharing peripheral sets with other members like the ATSAML10D14A-MUT but differing in physical footprint.

Replacement Considerations

The ATSAML10D14A-MUT serves as a functional equivalent within the same series but utilizes a 24-VQFN package instead of the 24-SSOP. Designers must account for significant PCB layout changes due to the difference between surface-mount QFN and SSOP footprints. Other variants in the ATSAML10D14A series may offer different memory sizes or package types but maintain core compatibility.
