That means you can't execute code directly from external memory and access to it would be rather slow.</BODY></HTML> Sat, 05 Dec 2009 19:46:31 GMT scifi 2009-12-05T19:46:31Z MCF5223X and external RAM/FLASH https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/MCF5223X-and-external-RAM-FLASH/m-p/159655#M4953 <HTML><HEAD></HEAD><BODY><P>Hello,</P><P>&nbsp;</P><P>Is it possible to interface an external SRAM or FLASH to this family of MCU ?</P><P>Thanks in advance.</P><P>&nbsp;</P><P>Peter.</P></BODY></HTML> Sat, 05 Dec 2009 19:25:12 GMT https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/MCF5223X-and-external-RAM-FLASH/m-p/159655#M4953 sili 2009-12-05T19:25:12Z Re: MCF5223X and external RAM/FLASH https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/MCF5223X-and-external-RAM-FLASH/m-p/159656#M4954 <HTML><HEAD></HEAD><BODY>Since the MCF5223x family lacks an external bus, you can only interface external memory through SPI, I2C, GPIO or similar.
