MSP430F5259 1.8V Split Rail I/O

Other Parts Discussed in Thread: CC2530, MSP430F5259, SN74AVC2T245


I am planning to use MSP430F5259 with CC2530 in my application. The communication between two is based on the USCI-UART mode of UCA0 of Port 3.

As I come to know that MSP430F5259 is having 1.8V I/O and CC2530 is having 3.3V I/O.

If I will directly connect both of them, then in UART communication, is any voltage level issue appear?
