Hello SL,
Exactly. The expansion header is where the SDRAM board from TIDM-TM4C129XSDRAM is connected and similar can be done for ULPI (USBHS) and external PHY.
On TM4C123x device you can use USB and SD cards as external storage, but a file system will be required. You might be able to connect a serial Flash too.
TM4C129x device has EPI. This allows the addition of external memory. Please refer the following…
I was able to confirm the EPI clock through the ALE. Table 32-41 says this signal should be 1 EPI clock.
The duration is ~17ns or 60MHz with EPIDividerSet(EPI0_BASE, 1);
The duration is ~8ns or 120MHz with EPIDividerSet(EPI0_BASE, 0); //too fast
This…
This is an example of interfacing TM4C194 with external Falsh.

In the TIVAWare examples, you can find some ethernet examples.
Thanks and regards,

Other Parts Discussed in Thread: TM4C129XNCZAD Hi,
I'm looking at the Interfacing SDRAM Memory on High Performance Microcontrollers (TIDM-TM4C129XSDRAM) design guide, and I don't understand why the RFSH value is set as it is.
RFSH is set to a…
Hello Bharath,
Generl-Purpose mode is described in detail in section 11.4.4 of the Datasheet/Technical Reference Manual. Have you had an opportunity to review this information to see if it helps you in your project? Also, you may want to have a look at…
