However, you have specified using a 10 ns SRAM which is very quick so it may be comparable. Also, SDRAM operation at 200 MHz is not supported on the LPC43xx (the maximum is 120 MHz).</SPAN><BR /><BR /><SPAN>-Dave @ NXP</SPAN></BODY></HTML> Wed, 15 Jun 2016 18:48:27 GMT https://community.nxp.com/t5/LPC-Microcontrollers/SDRAM-vs-SRAM/m-p/562957#M16584 lpcware 2016-06-15T18:48:27Z Re: SDRAM vs SRAM https://community.nxp.com/t5/LPC-Microcontrollers/SDRAM-vs-SRAM/m-p/562958#M16585 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by tomkulaga on Wed Feb 06 13:47:17 MST 2013</STRONG><BR /><SPAN>Thanks for that</SPAN></BODY></HTML> Wed, 15 Jun 2016 18:48:27 GMT https://community.nxp.com/t5/LPC-Microcontrollers/SDRAM-vs-SRAM/m-p/562958#M16585 lpcware 2016-06-15T18:48:27Z
