Some pins are designed to work with a 3.3V logic level, while others are designed for a 2.0V logic level. This is due to the different internal circuitry and electrical characteristics of the pins.</P> <P>BR</P> <P>Hang</P> Mon, 05 Aug 2024 08:00:46 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Voltage-level-I-O-pins/m-p/1925091#M56586 Harry_Zhang 2024-08-05T08:00:46Z
