  • RE: TM4C1290NCPDT: interfacing with eMMC

    Hello Garret, We cannot support eMMC with TM4C devices. I would suggest using QSSI memory devices that work well with our TM4C devices. We have a reference design that shows how to implement this: http://www.ti.com/tool/TIDM-TM4C129SDRAMNVM

  • RE: TM4C129ENCPDT: Possibility to extend the tm4c129 ram

    Resolved
    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

  • RE: TM4C1294NCPDT: TM4C1294NCPDT

    Hello Raone, The EPI is not suited for NAND Flash typically, and it would not work for this NAND Flash as the EPI needs address pins to connect to in order to read memory from specific addresses. Usually NAND Flash is connected with Quad SSI. That…

  • RE: TM4C1294NCPDT: Memory control is verified by connecting SDRAM and QSPI-FlashROM to TM4C1294NCPDT.

    Hi, Conor said: Q1 When using EPI0S as an address bus and data bus, is it necessary to process a pull-up resistor, etc.? Q2 No. That is not necessary. Conor said: Q2 Is it necessary to process the pins of the memory control lines assuming that…

  • RE: TM4C129XNCZAD: EPI interface question

    Hello Rob, robert bond said: Does the above pin assignment look correct? That depends a lot on what mode you want to use and what your SRAM needs. If I compare that to Host Bus 16 signals for no address MUX, then that is correct. EPI0S30 can also…
