ATSAML11D16A-YUT Equivalent & Substitute Parts

Part Overview

The ATSAML11D16A-YUT is an ARM Cortex-M23 SAM L11 microcontroller IC manufactured by Microchip Technology. This 32-bit single-core embedded processor operates at 32MHz with 64KB FLASH program memory, 16KB RAM, and 2KB EEPROM. The device integrates multiple connectivity interfaces including I2C, LINbus, SPI, and UART/USART, along with essential peripherals such as DMA, PWM, WDT, and brown-out detection. Currently in active product status with 2053 units in stock, this microcontroller is widely used in embedded applications requiring low-power operation across the 1.62V to 3.63V supply range. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the SAM L-series product line.

Engineering Selection Recommendations

Both the ATSAML11D16A-YUT and ATSAML10D16A-YUT are active products from Microchip Technology with full compliance to ROHS3 and REACH regulations. Selection between these parts should be based on packaging availability and supply chain considerations rather than functional differences.

The ATSAML11D16A-YUT is supplied in Cut Tape (CT) packaging with 2053 units currently in stock. The ATSAML10D16A-YUT is supplied in Tape & Reel (TR) packaging with 2599 units in stock. Both parts maintain identical electrical and mechanical specifications, ensuring direct substitution capability in 24-SSOP surface mount applications.

Moisture sensitivity levels differ between the two parts: ATSAML11D16A-YUT is rated MSL 3 (168 Hours), while ATSAML10D16A-YUT is rated MSL 2 (1 Year). This distinction may influence storage and handling requirements depending on manufacturing environment conditions.

Frequently Asked Questions (FAQ)

Q: Can ATSAML10D16A-YUT replace ATSAML11D16A-YUT in existing designs?

A: Yes. Both parts share identical electrical specifications including processor architecture, memory configuration, operating frequency, voltage range, I/O count, and connectivity interfaces. The 24-SSOP package dimensions and surface mount compatibility are also identical, enabling direct substitution without circuit modification.

Q: What is the difference between SAM L11 and SAM L10 series designations?

A: Within the D16A configuration, both series provide identical core functionality and electrical characteristics. The series designation reflects product line organization within Microchip's portfolio but does not indicate functional differences for these specific part numbers.

Q: Are there packaging differences between these parts?

A: Yes. The ATSAML11D16A-YUT is supplied in Cut Tape (CT) packaging, while the ATSAML10D16A-YUT is supplied in Tape & Reel (TR) packaging. Both use the same 24-SSOP physical package format with identical dimensions and pin configuration.

Q: Do moisture sensitivity levels affect substitution?

A: Moisture sensitivity levels (MSL) affect storage and handling procedures but do not impact electrical or mechanical compatibility. ATSAML11D16A-YUT (MSL 3, 168 Hours) requires more frequent baking cycles than ATSAML10D16A-YUT (MSL 2, 1 Year) in high-humidity manufacturing environments. Select based on your facility's moisture control capabilities.

Q: Are both parts currently available?

A: Yes. Both parts maintain active product status with current inventory: ATSAML11D16A-YUT (2053 units) and ATSAML10D16A-YUT (2599 units).

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for embedded microcontroller applications.
