Engineering Selection Recommendations

Both the ATSAML10E16A-AUT and ATSAML11E16A-AUT are active products from Microchip Technology with full RoHS3 compliance and identical electrical specifications. Selection between these parts should be based on packaging and procurement requirements rather than functional capability.

ATSAML10E16A-AUT is supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly operations where component feeding systems require continuous tape packaging.

ATSAML11E16A-AUT is supplied in Cut Tape (CT) format, appropriate for lower-volume applications, prototyping, or situations where smaller quantity procurement is required.

Both parts maintain identical pinout, memory configuration, and peripheral functionality, ensuring direct substitution at the circuit board level without design modifications.

Frequently Asked Questions (FAQ)

Q: Can ATSAML11E16A-AUT replace ATSAML10E16A-AUT in production designs?

A: Yes. Both parts share identical electrical specifications, pinout, memory configuration, and peripheral functionality. The only difference is packaging format (Tape & Reel versus Cut Tape). No circuit board redesign or firmware modification is required.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging provides the same components on shorter tape segments, typically used for lower-volume orders or manual assembly processes. Both formats contain identical components with the same specifications.

Q: Are there any differences in the 32-TQFP package between these parts?

A: No. Both parts use identical 32-TQFP (7x7) packages with matching pinout, footprint, and mechanical dimensions. PCB layouts and component placement are interchangeable.

Q: Do both parts support the same supply voltage range?

A: Yes. Both ATSAML10E16A-AUT and ATSAML11E16A-AUT operate across the identical voltage supply range of 1.62V to 3.63V, ensuring compatibility in power supply designs.

Q: Are firmware and software compatible between these parts?

A: Yes. Both parts use the identical ARM Cortex-M23 processor core, memory architecture, and peripheral configuration. Firmware compiled for one part executes identically on the other without modification.

Q: What is the inventory status for each part?

A: ATSAML10E16A-AUT has 3070 pieces in stock. ATSAML11E16A-AUT has 967 pieces in stock. Both are actively produced and available for immediate procurement.
