[Cryptech Tech] arm

[Hannes Tschofenig]

It might be good to know how much data you want to exchange.

The I2C bus exchanges data at a rate up to 1 Mbit/s.

The chips typically come with a number of other interfaces as well. For
example, USART (11.25 Mbits/s) and SPI (45 Mbits/s) interfaces.

The speed will vary across chips.
