Can LPC802 IO support 5V voltage pull high

[li-chinwang]

Customer plan to use LPC802 to connect to an 5V CODEC via 5V pull up I2C.

Since LPC802/804 input can support max 5.4V voltage, can customer do so in HW without level shift?

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
It's necessary to need a level shift in this implementation, just in case.
Have a great day,
TIC
