What is the difference between TMS320VC5501 and TMS320VC5502

Other Parts Discussed in Thread: TMS320VC5502, TMS320VC5501

Hi,

Apart from the difference of Max Freq, HPI, McBSP, RAM, what is the functional difference between TMS320VC5501 and TMS320VC5502?

Can I replace TMS320VC5502 with TMS320VC5501, if my application requires only 8-bit HPI, 2 McBSP and 32K RAM? VC5501 is half the price of VC5502.

Please let me know.

Thank you.

Regards,

Archana.

    Hello Archana,

         With respect to your application : "only 8-bit HPI, 2 McBSP and 32K RAM" - Yes, you can use C5501 device.

         Also for further details on C5502 & C5501  you can refer specific datasheets.

         C5501 Datasheet  & C5502 Datasheet

         Hope the above information helps .

    Regards

    I believe so by comparing the required functions as you stated, packages and pinouts. I would believe you should have own testing procedures to confirm your requirements.

    Regards.

    Also, below table illustrates the Major difference between the C5501 and C5502 :

                C5501            C5502 
       
    − 3.33-ns Instruction Cycle Time for
    300-MHz Clock Rate    		 3.33-/5-ns Instruction Cycle Time
    – 300-/200-MHz Clock Rate
       
    16K x 16-Bit On-Chip RAM That is
    Composed of Four Blocks of 4K × 16-Bit
    Dual-Access RAM (DARAM) (32K Bytes)    		 32K X 16-Bit On-Chip RAM That is Composed
    of Eight Blocks of 4K X 16-Bit Dual-Access
    RAM (DARAM) (64K Bytes)
       
    − Two Multichannel Buffered Serial Ports
    (McBSPs)    		 Three Multichannel Buffered Serial Ports (McBSPs)
       
    8-Bit Parallel Host-Port Interface (HPI) 8-Bit/16-Bit Parallel Host-Port Interface (HPI)
       

     Hope this will be useful.

    Hello Steve, Vasantha,

    Thank you for the replies.

    I have one more doubt about the firmwares. How does the roll back from VC5502 to VC5501 affect firmware?

    Thanks,

    Archana.

    Hello Archana,

    With respect to firmware changes, if any of the C5502 feature is used (Refer to the C5502 table), then yes this would involve firmware changes too.

    Regards

    ok. That means as per the 5502 table, if I am using McBSP or 16-bit HPI..correct?

    Else, the same firmware would work for both VC5502 and 5501, if only 2 McBSPs are used and 8-bit HPI is required.

    (considering external hardware pull ups/down requirements)

     

    Thanks,

    Archana.
