Code Migration Between STM32WL55xx Chips

[Jakob]

I developed a program that was based off of the STM32WL55JC1 Nucleo board and SubGhz PingPong example. Working to create my own PCB and wanted to place the STM32WL55CCU6 on my board instead of STM32WL55JCI chip as the package seems easier to work with. From looking at data sheet it appears like they are the same chip just with different packages and different number of GPIOs broken out. Assuming I copy files over to a STM32WL55CCU6 project generated on CubeMX will it run without modificatitons or at least little modification?

Hello @Jakob and welcome to the Community,

Comparing the two mentioned MCUs pin to pin, we can see that they are not fully compatible is some features and peripherals such as: package, GPIOs, ADC.

• STM32WL55JCIx is a UFBGA73 package with 43 I/O and 12xADC.
• STM32WL55CCUx is an UFQFPN48 package with 29 IO and 9x ADC

So, you should pay attention in pins and features differences.
