Other Parts Discussed in Thread: TMS320F2808

Hello,

We are looking for solar grid inverter controller, and found F2808 from TI, but this is old part? Do TI recomment new part?

 

Thanks

    The TMS320F2808 is still a viable device, but yes there are other devices that could be appropriate.

    Please see the MCU selection tool to find other C2000 devices as well as the System Block Diagram for Solar Inverters.

    The F2808 is part of the 0x series and a member of the Fixed Point Family.

    This link has information on the different families and series in C2000:
    http://focus.ti.com/mcu/docs/mcuprodoverview.tsp?sectionId=95&tabId=1531&familyId=916

    F28:

    Fixed Point Series:
    1x: 2003 Production
    0x: 2005 Production
    23x: 2008 Production

    Piccolo Series:
    02x: Planned 2009 Production (samples & tools now)
    03x: Planned 2010 Production (samples & tools now)

    Delfino Series: Floating Point
    33x: 2008 Production
    34x: Imminent 2009 Production (samples & tools now)

    These span from $1.80 to $16 1KU, 40 to 300 MHz, fixed/floating-point or control law acceleration.

    F2808 (and all 0x series) is certainly a valid device and is still considered in the "production ramp" phase of it's lifecycle.  Customer are still beginning new designs and the 0x series will ship for many more years.

    We have solar inverter customers worlwide using different devices from all of our series based on performance and price needs (F2812 is very popular at the high end, F2808/9/044 at the mid-end, and F2802-60/F28015 at the low-end).

    For newest designs customer are using our lowest cost 02x devices for new micro-inverter designs, and our high performance floating point 33x series for grid-tied and other performance driven applications (like wind/turbine inverters).

    The most popular tool for this application is the Renewable Energy Kit:
