Problem with a timer counter.

I set a timer to count 500us ticksTIM_InitStruct.Prescaler = (uint16_t)40000-1; //SYSCLK = 80Mhz – 80Mhz/40000 = 500us TIM_InitStruct.CounterMode = LL_TIM_COUNTERMODE_UP; TIM_InitStruct.Autoreload = 0xFFFFFFFF; //TIM2 – 32-bit c...

stm32 with 8 uarts and a small footprint

I'm searching for a stm32 with 8 uarts for io-link. But there is no way I can search for peripherals. So any suggestions, preferably in LQFP-48 or something similar small.Thanks.
