It can support basic UART with DMA interface function, x4 to x32 oversampling of baud-rate.This module supports LIN slave operation.</P><P>The module can remain functional in VLPS mode provided the clock it is using remains enabled. It can support ISO7816.</P><P></P><P>UART1 and UART2 are basic universal asynchronous receiver/transmitter (UART) modules with DMA function support. Generally, these modules are used in RS-232, RS-485, and other communications. This module supports LIN Slave operation.</P><P></P><P>UART pins are digital. So the operation voltage depends on VDD voltage value.</P><P></P><P>Hope my reply can help you.</P><P></P><P>Best Regards</P><P>Paul</P></BODY></HTML> Mon, 17 Mar 2014 04:12:11 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/UART-on-kl25z/m-p/296733#M12230 Paul_Tian 2014-03-17T04:12:11Z
