I will communicate with a device via SMBus. I use PIC18F26K83 for this. In SMBus spec it says clock minimum clock frequency is 10 kHz and maximum clock frequency is 100 kHz. Would it be a risk to use 100 kHz clock frequency since it is the boundary and max limit? Or is it safer to go with 75 kHz for example?
I will be using multiplexer and communicating with 3 smart batteries. Reading their SOC and send these data with UART to another PIC. Cable length from batteries to PIC will not be more than 1 meter long. I am planning to make MCU clock also 100 kHz.
