Need in Microprocessor IC with next requirements

nzif frunze
Intellectual 370 points
Other Parts Discussed in Thread: AM1705

Our minimal requirements are next:

1. QFP body, not BGA

2. NAND interface for flash (to use single large NAND flash IC instead of number of ICs (for example - on 1705 - we can use 3 NOR  ICs with 32M space, not one NOR with 128M))

3. SDRAM interface for RAM (needed to run OS)

4. One Ethernet / MAC

5. One USB

6. Three UARTs

7. Linux OS (for using different applications in energy monitoring and accounting systems)

Please  help us to choise some TI devices?

With Regards.

    Hi

    I believe from the Sitara product line, AM1705 would be the closest fit to what you are looking for.

    1) Available in QFP package

    2) Supports 8 bit NAND flash

    3) EMIFB 16 bit SDRAM interface

    4) EMAC support (RMII)

    5) USB2.0

    6) 3 UARTs

    7) Linux OS supported.

    I see that you might've already looked at AM1705, was there a reason that it did not match your requirements?

    I see that w.r.t NAND flash, the support for 8 bit NAND is not highlighted in the first page of the datasheet, but it *is* supported on AM1705.

    Let us know if you have additional doubts on this.

    Regards
