AM4378: duration of time required to transfer the data

Hello Renan, 

Thank you for the query.

Please ask customer to provide additional details on what he is looking for.

Helo Kallikuppa,

My customer "wanted to calculate the time required for the data transfer through SPI communication protocol".

Renan

Hello Renan, 

There are configurations to be made for SPI interface. The above statement is generic.

More details would help.

I am checking internally if there is a way to estimate this.

Hi Renan,

First of all TTL Serial Communication is very low power; even at the fastest rates and at 3.3V the total power consumed in a steady state environment is only a few mW (so low that for a several Watt part we often do not prioritize these measurements).

Second of all the time it takes for 'the data to complete the transfer' is a function of both the total size of the message and also the baud rate of the serial clock. 

Why is this measurement needed? What is the objective to confirm 1-3mW of consumption?

Regards,

Colin
