MCU comparison script

Pascal4275
Expert 2045 points

Hello everybody!

I'm not sure this is the right place to write this, but here is a little contribution to TI's MCU ecosystem.

I have a student who comes here a few hours a week, and here is a small php application he wrote:

http://passworld.co.jp/index.php?lang=GB&lieu=MCUSel

Bookmark it!

It helps you to spot the differences between 2 (or more) devices. I think it's quite accurate because

it's based on TI data, processed directly by the script (i.e. no manual editing).

Please tell me if you have any comment, hint to improve it, etc...

    Hello Pascal,

    nice script. It would be great if you could add the TI SOCs (CC430-Series, ...). Has someone a link or hint for an application like this which compares the MCUs or SOCs of different manufacturers?

    Nice program indeed.

    However, jsut the first check revealed a 'problem'.

    I wanted to compare the 5419 and the 5419A. But the program lists the 5419A as 5419 and does not know about the 'real' 5419. (the most obvious difference is the 25MHz vs. 18MHz system clock)

    Also, I'm not really sure about the PWM and capture values.

    PWM 15
    Capture Pins 10

    IMHO, there are 15 capture pins and 12 PWM outputs. And only 3 timers if you don't count the WDT and the RTC as timer (5 if you do, but the program lists 4)

    Hello!

    Thanks for the feedback. The script we made uses TI data. If you look at that page:

    http://focus.ti.com/en/multimedia/flash/selection_tools/mcu/mcu.html

    you can notice that there is only one device 5419, no 5419A.

    Beside this, the data I display is TI data. PWM = 15, capture pins = 10 comes from the above page.

    And similarily for the timers...

    Beside this, the data is not up to date (therefore the FRAM devices are not listed). And I noticed that

    TI's export format has changed, so I will need a few hours to update, but I have no time now.

    Thanks,

    Pascal

    Yes, I see, the data on the selection tool is wrong.

    The MSP selection tool does only list the A types, but not the non-A, while the one you used does list teh A types but without the A in the name. And the timer/capture/PWm info is wrong too.

    entering correct data for a selection tool seems to be a really difficult task. Whoever did the job, he did a good job, but not good enough.

    The "MSP only" selection tool on http://www.ti.com/lsds/ti/microcontroller/16-bit_msp430/product_search.page correctly lists 3 timers for the 5419A. And does not list PWM/capture pins at all.
