ATSAML11D15A-MFT Equivalent & Substitute Parts

Part Overview

The ATSAML11D15A-MFT is an ARM Cortex-M23 SAM L11 microcontroller IC manufactured by Microchip Technology. This 32-bit single-core embedded processor operates at 32MHz with 32KB FLASH program memory, 8KB RAM, and 2KB EEPROM. The device is housed in a 24-VQFN (4x4) surface mount package with an exposed pad. The ATSAML11D15A-MFT maintains Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the SAM L10 and SAM L11 series microcontrollers.

Substitute Part Grouping Explanation

The ATSAML10D15A-MFT qualifies as a parametric equivalent substitute based on the following criteria:

Electrical Equivalence: Both parts share identical core processor architecture (ARM Cortex-M23), operating frequency (32MHz), program memory capacity (32KB FLASH), RAM allocation (8K x 8), EEPROM size (2K x 8), I/O count (17), connectivity interfaces (I2C, LINbus, SPI, UART/USART), peripheral features (Brown-out Detect/Reset, DMA, POR, PWM, WDT), data converter specifications (A/D 5x12b; D/A 1x10b), supply voltage range (1.62V ~ 3.63V), and operating temperature range (-40°C ~ 125°C).

Mechanical Compatibility: Both parts use identical surface mount packaging: 24-VFQFN Exposed Pad (4x4mm footprint).

Compliance Alignment: Both parts maintain ROHS3 compliance, identical MSL rating (3, 168 Hours), and REACH Unaffected status.

Series Differentiation: The primary distinction is the product series designation—ATSAML11D15A-MFT belongs to the SAM L11 series, while ATSAML10D15A-MFT belongs to the SAM L10 series. Both series employ the same ARM Cortex-M23 architecture with matching electrical and mechanical specifications for this specific part number variant.

Parameter Comparison

Engineering Selection Recommendations

Both the ATSAML11D15A-MFT and ATSAML10D15A-MFT maintain Active product status from Microchip Technology, ensuring continued manufacturing support and availability. Both parts carry ROHS3 compliance certification and REACH Unaffected status, meeting regulatory requirements for industrial and commercial applications.

Selection between these parts should be based on packaging requirements: the ATSAML11D15A-MFT is supplied in Cut Tape (CT) format, while the ATSAML10D15A-MFT is supplied in Tape & Reel (TR) format. Cut Tape packaging is suitable for lower-volume applications and manual assembly processes, whereas Tape & Reel packaging is optimized for high-volume automated assembly operations.

From an electrical and mechanical standpoint, both parts are functionally interchangeable for applications requiring ARM Cortex-M23 microcontrollers with 32KB FLASH, 8KB RAM, 32MHz operation, and 24-VQFN surface mount packaging.

Frequently Asked Questions (FAQ)

Q: Are the ATSAML11D15A-MFT and ATSAML10D15A-MFT electrically identical?

A: Yes. Both parts share identical electrical specifications including core processor (ARM Cortex-M23), operating frequency (32MHz), memory configuration (32KB FLASH, 8KB RAM, 2KB EEPROM), I/O count (17), connectivity interfaces (I2C, LINbus, SPI, UART/USART), peripheral features, data converters, supply voltage range (1.62V ~ 3.63V), and operating temperature range (-40°C ~ 125°C).

Q: Can these parts be used interchangeably on the same PCB?

A: Yes, from a mechanical and electrical standpoint. Both parts use identical 24-VFQFN Exposed Pad surface mount packaging with the same footprint and pin configuration. No PCB redesign is required for substitution.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging supplies individual component strips cut to specified lengths, suitable for small-quantity orders and manual assembly. Tape & Reel (TR) packaging supplies components on continuous reels optimized for automated pick-and-place assembly equipment in high-volume production environments.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ATSAML11D15A-MFT and ATSAML10D15A-MFT are ROHS3 compliant, carry MSL rating 3 (168 Hours), and maintain REACH Unaffected status.

Q: Why are there two different series designations (SAM L11 vs. SAM L10) if the parts are equivalent?

A: The SAM L11 and SAM L10 series represent different product lines within Microchip's ARM Cortex-M23 microcontroller portfolio. For the D15A variant with 32KB FLASH and 8KB RAM, both series offer identical electrical specifications and mechanical packaging. Series designation reflects product family categorization rather than functional differentiation for this specific part number configuration.

Q: Are both parts currently in production?

A: Yes. Both parts maintain Active product status with Microchip Technology, ensuring continued availability and manufacturing support.
