Hi

According to the Murata's manual, the CMWX1ZZABZ-091 module uses an STM32L082 processor, but the ST website says it uses an STM32L072CZ. What information is correct?

I am asking this question because the Murata manual does not reference all the alternate functions available on a given STM32L0 pin.

For example in the Murata manual, PA12 / USB_DP is connected to STM32L082_PA12 and has the description GPIO Mode PA12 and USB_DP.

According to the STM32L072 manual, pin PA12 can have the following alternative functions: SPI1_MOSI, EVENTOUT, TSG_G4_I04, USART1_RTS_DE and COMP2_OUT.

Can I use all the alternate STM32L0 functions on the Murata Lorawan Module?

Hello!

From Murata's "LoRa Module FAQ":

Q. What is the difference between CMWX1ZZABZ-078 and CMWX1ZZABZ-091?

A. In terms of the performance and the software, basically there is no difference between these two modules. The only difference is the Hardware Encryption for AES.

CMWX1ZZABZ-078 carries this function, but CMWX1ZZABZ-091 does not. Besides, the price is the same for both modules.

CMWX1ZZABZ-078 - STM32L082

CMWX1ZZABZ-091 - STM32L072

>According to the STM32L072 manual, pin PA12 can have the following alternative functions: SPI1_MOSI, EVENTOUT, TSG_G4_I04, USART1_RTS_DE and COMP2_OUT.

From manual 072: "Alternative functions: SPI1_MOSI, EVENTOUT, TSG_G4_I04, USART1_RTS_DE and COMP2_OUT." and "Aditional functions: USB_DP"
