Direct replacement for STM32WLE5CCU6

[DCarv]

Hi,

I have a project that use the STM32WLE5CCU6 and I want to make a variation of this project without RF communication.

Can you suggest me a reference to replace this MCU taking advantage of existing firmware without major changes. Preferably cheaper.

Thanks

I don't think there is a software or pin compatible equivalent part.

CubeMX should have a pin matching tool​

Correct, there is currently no pin-compatible MCU for the STM32WLE5 - a WLE5 without RF frontend, so to speak. The pins of other STM32 in UFQFPN48 are arranged completely differently, even the OSC pins for the crystals, NRST and the VDD/VSS pins are located elsewhere, not to mention the GPIOs.

Good luck anyway!

Regards

Hello @DCarv​,

I think the How to find compatible devices for an MCU? STM32G473CB as example article can help you finding the convenient device from the ST portfolio for your application.

Thank you.
