I think that I am equivalent to FB3, and is it right?</P></BODY></HTML> Mon, 28 Oct 2013 00:12:27 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/for-flexbus/m-p/235748#M5421 okubohitoshi 2013-10-28T00:12:27Z Re: for flexbus https://community.nxp.com/t5/Kinetis-Microcontrollers/for-flexbus/m-p/235749#M5422 <HTML><HEAD></HEAD><BODY><P>About Flexbus timing, the time from CLK_RISE to FB_CS (control signals) is covered by the FB3 spec, the time from CLK_RISE to input Date hold time spec is FB5.</P><P>FYI: The latest <SPAN style="color: #3d3d3d; font-family: 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif;">MK20FN1M0VLQ12</SPAN> datasheet is Rev.5, you can find it from below link:</P><P><A href="http://cache.freescale.com/files/microcontrollers/doc/data_sheet/K20P144M120SF3.pdf" title="http://cache.freescale.com/files/microcontrollers/doc/data_sheet/K20P144M120SF3.pdf">http://cache.freescale.com/files/microcontrollers/doc/data_sheet/K20P144M120SF3.pdf</A></P><P>Wish it helps.</P></BODY></HTML> Wed, 30 Oct 2013 06:05:39 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/for-flexbus/m-p/235749#M5422 Hui_Ma 2013-10-30T06:05:39Z
