AN60580 - SIO Tips and Tricks in PSoC® 3 / PSoC 5LP

Last Updated:

*I

The special input/output (SIO) pins provide differential input buffer and a means to regulate the high-level output voltage (VOH). The SIO pins are tolerant to input voltages higher than the I/O supply voltage and can sink up to 25 mA current. This application note explains the following applications of SIO pins: comparator, charge pump, Salen-key filter, level shifter, half wave rectifier, peak detector, and sleep wakeup using SIO comparator.

The following video gives introduction to the features of SIO pins.
