Part Number: TM4C129ENCPDT

Hello,

is there a way to expand the RAM of the TM4C129?

Hello Msark,

You can extend RAM with external chips by using the EPI interface like this TI Design: http://www.ti.com/tool/TIDM-TM4C129SDRAMNVM

Is SDRAM the only way to extend the RAM?
As far as I know the SDRAM must always be updated. Who cares about the constant updating, the periphery?

Hello Krams,

There are SDRAM which do auto refresh, like the SDRAM we used in the TI Design which is: http://www.issi.com/WW/pdf/42-45R-S_86400D-16320D-32160D.pdf

It's not the only way, but it is the most cost efficient way, and with auto refresh there really isn't an issue with the constant updating anymore.
