Re: Jan 16 - Part 3. Low-Power Peripherals

There was a question from Class 3 slide 19 on Serial Ports in Low Power Designs. One of the bullets is -

- Transmission/Reception

    - Data length

    - Phase, MSB, Polarity

These are just common characteristcis  of serial ports and don't have any appreciable effect on power dissipation.

The key low power point of this slide is really the table that shows the Total Charge needed to transfer data by UART, I2C and SPI. Typically the faster you can send data the lower the overall power (total charge) will be. Backwards from what you might expect!
