Can I get a summary of the differences between the TMS320VC5409 and TMS320VC5409A?

Other Parts Discussed in Thread: TMS320VC5409A

Hi Champs,



I'm planning to use TMS320VC5409APGE16 because of TMS320VC5409PGE100 EOL.
So, I'd like to get a summary of the differences between the TMS320VC5409 and TMS320VC5409A.
Could you please let me know the summary of the differences?



Thank you in advance for your cooperation.


Best regards,
j-breeze

    Hi,

    This is quite an old part and I could locate any document which presents exact difference between these two parts. But based on the datasheet reference, below is the major difference that I identified.The major difference is in package, FP execution time & power supply. 

     

    C5409A

     

    C5409

    On chip Peripherals –

     

    Enhanced external parallel interface (XIO2)

     

     

     

     

    Packaging :

     

    144-Pin Ball Grid Array (BGA) (GGU Suffix)

    144-Pin Low-Profile Quad Flatpack (LQFP) (PGE Suffix)

     

     

    Packaging :

     

    Available in a 144-Pin Plastic Thin Quad

    Flatpack (TQFP) (PGE Suffix) and a 144-Pin

    Ball Grid Array (BGA) (GGU Suffix)

    Fixed point execution time:

     

    6.25-ns Single-Cycle Fixed-Point Instruction

    Execution Time (160 MIPS)

    8.33-ns Single-Cycle Fixed-Point Instruction

    Execution Time (120 MIPS)

     

    Fixed point execution time:

     

    12.5-ns Single-Cycle Fixed-Point

    Instruction Execution Time (80 MIPS)

    Power Supply

     

    3.3-V I/O Supply Voltage (160 and 120 MIPS)

    1.6-V Core Supply Voltage (160 MIPS)

    1.5-V Core Supply Voltage (120 MIPS)

     

     

    Power Supply

     

    1.8-V Core Power Supply

    1.8-V to 3.6-V I/O Power Supply Enables

    Operation With a SIngle 1.8-V Supply or

    With Dual Power Supplies

     

     

    Hope this helps. If I find any related document I would update again here.

    Also, recommend you to consider other C55xx newer devices ( if its feasible).

    Regards

    Hi Vasanth,

    Thank you for your useful information.
    Actually, one of my customers asked the differences and he does not want to migrate to C55xx.
