Substitute Part Grouping Explanation

Substitute parts for the ATSAML11D16A-MFKPH are identified based on strict equivalence across the following critical parameters:

Core processor architecture (ARM Cortex-M23)
Memory configuration (64KB FLASH, 16KB RAM, 2KB EEPROM)
Operating frequency (32MHz)
I/O count (17 pins)
Connectivity interfaces (I2C, LINbus, SPI, UART/USART)
Data converter specifications (A/D 5x12b, D/A 1x10b)
Supply voltage range (1.62V ~ 3.63V)
Operating temperature range (-40°C ~ 125°C)
Package type (24-VQFN 4x4 with exposed pad)
Compliance certifications (ROHS3, REACH Unaffected)

The ATSAML11D16A-MF and ATSAML10D16A-MF meet these equivalence criteria and are classified as parametric equivalents. Differences in packaging designation (MFKPH vs. MF) and ECCN classification do not affect functional or electrical compatibility.

Engineering Selection Recommendations

All three parts listed—ATSAML11D16A-MFKPH, ATSAML11D16A-MF, and ATSAML10D16A-MF—maintain active production status with Microchip Technology. Each part carries ROHS3 compliance and REACH Unaffected certification, meeting current environmental and regulatory requirements for embedded applications.

The ATSAML11D16A-MFKPH and ATSAML11D16A-MF differ only in packaging designation and ECCN classification; both are SAM L11 series devices. The ATSAML10D16A-MF belongs to the SAM L10 series but maintains identical electrical specifications, memory configuration, and pin count. Selection between these parts depends on supply chain availability, inventory status, and specific procurement or export requirements related to ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can ATSAML10D16A-MF be used as a direct replacement for ATSAML11D16A-MFKPH?

A: Yes. Both devices share identical core processor architecture, memory configuration (64KB FLASH, 16KB RAM, 2KB EEPROM), operating frequency (32MHz), I/O count (17), connectivity interfaces, data converter specifications, supply voltage range, operating temperature range, and package type (24-VQFN 4x4). The difference in series designation (SAM L10 vs. SAM L11) does not affect functional compatibility when electrical and mechanical parameters are equivalent.

Q: What is the difference between ATSAML11D16A-MFKPH and ATSAML11D16A-MF?

A: These parts are electrically and mechanically identical. The difference lies in packaging designation (MFKPH vs. MF) and ECCN classification (5A992C vs. 5A992C). Both are SAM L11 series devices with active production status. Selection may depend on procurement requirements or export regulations.

Q: Are all three parts compatible with the same PCB layout?

A: Yes. All three parts use the 24-VQFN (4x4) package with exposed pad, identical pin count (17 I/O), and identical pin assignments. PCB layout and footprint design remain unchanged across all three part numbers.

Q: What is the moisture sensitivity level for these parts?

A: All three parts carry MSL rating 3 with a 168-hour floor life. Standard moisture control procedures during storage and handling apply.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH Unaffected, meeting current environmental regulations for electronic components.
