AN1116: EFM8UB1/2 to EFM8UB3 Compatibility and Migration Guide
This porting guide is targeted at migrating an existing design from a EFM8UB1 or EFM8UB2 to a EFM8UB3 microcontroller. Both hardware and software migration needs to be considered.
KEY POINTS:
• The EFM8UB3 maintains a high degree of pin and feature compatibility with EFM8UB1.
• Designs will require minimal hardware or software changes when migrating EFM8UB1 to EFM8UB3.
• EFM8UB3 is software compatible with EFM8UB2, only minor changes are required for common peripherals.
The Universal Bee family of EFM8 microcontrollers is ideal for space constrained USB applications. The family includes devices with a USB 2.0-compliant full speed controller. This application note highlights the differences between EFM8UB1, EFM8UB2, and EFM8UB3 microcontrollers. The EFM8UB3 family is designed to be largely code-compatible and pin-compatible with EFM8UB1 devices, and thus requires only minor changes when porting firmware and hardware between the two families. EFM8UB2 is not pin-compatible with EFM8UB1 and EFM8UB3. This document describes in detail what is required to integrate an EFM8UB3 into a design in place of an existing EFM8UB1 or EFM8UB2 device, respectively.
