STM32WL55 and STM32WLE5 HW compatibility

MMici.1
Associate II

Hi,

I would like to confirm that STM32WL55 and STM32WLE5 are mutually HW compatible from the point of external circuitry? I.e. can we use either one in a PCB originaly designed for one of them w/o any modifications? (Yes, I checked both datasheets but better to be safe than botching ;))

I know that "The STM32WL55 is a Dual core MCU (cortex-M4 and cortex-M0+) but the STM32WLE5 is using only one core (cortex-M4)." so there might be a difference from the FW perspecitve. 

 

Thank you
