AM1808 availability

Other Parts Discussed in Thread: AM1808

I recently started using an AM1808 Experimenter Kit.  I am fairly comfortable now that I can use Code Composer and write code to do what I need to do.  But, as I am early in the design phase, I am worried about the availability of the AM1808 in the future.  As I have not used ARM chips previously, I am not sure what their product cycles are like.  Is there any information on future availability of the AM1808?  I need the uPP on the AM1808 chips and I don't see this peripheral on the current AM series chips.  Is this a feature that I cannot count on being available in future chips?

  Is there a newer chip that I should be considering?

Thanks,

Aaron

    Hi Aaron

    I will use the standard communication on this

    TI recognizes its catalog products are sold to a wide variety of customers and used in a wide range of applications with expected production lifetimes in excess of 10 years.  As such, TI typically does not end-of-life products in less than 10 years.The AM1808 has not yet reached that 10 year mark and will not do so for another few years.

    So as such I don't think you need to worry about AM1808 device availability in coming years.

    However there are newer parts in the roadmap, that have bigger ecosystem for support, more and cheaper options for hardware evaluation platform, and equally and more feature rich. Have you looked at the AM335x series?

    As far as I know, we are not integrating uPP in any of the upcoming devices that are follow on to AM18xx (Cortex A8 and A15 series) and I also don't see it on the new c2000 + M3 device family. However uPP is available on the c28x Deflino floating point device family also.

    Hi Mukul,

      As you suggested, I looked more closely at the features of the newer AM335x series chips.  You indicated that the Universal Parallel Port (uPP) was not likely to be added to these chips.  Is the General Purpose Memory Controller (GPMC) meant to replace uPP where fast parallel data transfer is needed?

    Thanks,

    Aaron

    Hi Aaron

    GPMC has been on devices prior to them getting the uPP. it is somewhat equivalent in intent to what is EMIFA on AM1808. It allows hooking up to NAND, NOR and other parallel bus i/f  for FPGA etc.

    e.g.

    http://e2e.ti.com/support/arm/sitara_arm/f/791/t/162726.aspx

    Depending on the speed and what you are planning to hook up to uPP, GPMC should be a good candidate.

    If you have more questions on what i/f can be used from AM335x to interface what you were planning to i/f via uPP , I recommend posting a separate E2E post on the AM335x device forum

    http://e2e.ti.com/support/arm/sitara_arm/f/791.aspx

    This will allow additional subject matter experts to tell you about AM335x and the i/f choices.

    Regards

    Hi Mukul,

      I will look more closely at GPMC.

    Thank you for your assistance,
