We were shown an existing prototype that was built using the teensy 3.1 development board which host an <SPAN style="color: #000000; font-family: Arial, Helvetica, sans-serif; font-size: small;">MK20DX256 chip which has a </SPAN><SPAN style="color: #000000; font-family: Arial, Helvetica, sans-serif; font-size: small; line-height: 1.5em;">32 bit ARM </SPAN><SPAN style="color: #000000; font-family: Arial, Helvetica, sans-serif; font-size: small; line-height: 1.5em;">Cortex-M4 (</SPAN><SPAN style="color: #000000; font-family: Arial, Helvetica, sans-serif; font-size: small; line-height: 1.5em;">72 MHz). I was hoping to replace the current MCU with something&nbsp; with a similar core and Bluetooth Low Energy </SPAN><SPAN style="line-height: 19.5px; color: #000000; font-size: 10pt; font-family: Arial, Helvetica, sans-serif;">transceiver. I was looking the chips in the k series but the drop-off in processor speed seems huge. If anyone can help give some direction.</SPAN></P></BODY></HTML> Sun, 29 Mar 2015 04:41:34 GMT https://community.nxp.com/t5/University-Programs/Need-help-with-MCU-selection/m-p/360095#M326 olajuwon 2015-03-29T04:41:34Z Re: Need help with MCU selection https://community.nxp.com/t5/University-Programs/Need-help-with-MCU-selection/m-p/360096#M327 <HTML><HEAD></HEAD><BODY><P>The Kinetis KW2 runs at 50Mhz and has a thinner package than the KW20 series, this allows a better footprint and a thinner overall application packaging.
