inconsistent Information concerning STM32L071

There is an inconsistent information about the numbers of usart in series STM32L071KBTx and STM32L071KZTx

(both LQFP32.)

in the datasheet, it says there are 3 usart:


but in the STM32CubeMx, if I choose L071KBTx, I got 4 USART?!


Have I misunderstood something....?

There are totally 3 USART or 4 USART in this package??!!

I would like to know!

Thanks in advanced.




In the STMCU Finder pc software, if I choose STM32L0x1 and I request 4 USART,

then there will be no LQFP32 package in the result list. 

However, If I use STM32CubeMx, doing the same (choose STM32L0x1 and 4 usart), 

there will be STM32F071KB and STM32F071KZ in the result list.
