I am looking for a Cortex A8 evaluation board that has 32 bit ports

[fre]

I am looking for a Cortex A8 evaluation board that has  32 bit ports and USB port.   I am new to this and it may not be possible.   Do not need external memory or other peripherals, no operating system will be used.   Or third part board.

Hi,

If you are looking specifically for a Cortex-A8 core, you could refer to the i.MX50/53 family of Application Processors at the following link:

http://www.freescale.com/imx53

There is also available a newer family of Application Processors based on Cortex-A9, the i.MX6 family:

http://www.freescale.com/imx6

They are Application Processors, so, external Flash/RAM memories are required.

If you don’t want to use external memory and a lighter processing is required, you could consider the Kinetis K70 family of microcontrollers, based on Cortex-M4 at 150 MHz, with internal 128 KB of RAM and 1 MB of Flash:

All the options have USB controllers and many evaluation boards, either from Freescale or from third-parties.

Hope this will be useful for you.
Best regards!

Carlos:

I believes the A-8 is simpler than the A-9 (external Flash/RAM).    M-4 is slow.   The problem that I am having is that none of the evaluation boards that I have checked have 32 bit ports available.    There may be a third party board out there that has 32 bit ports that someone knows about.

Thank you,

Hi,

In case of the i.MX53 chip, it includes 7x32-bit GPIOs, but with shared functions. The routing of these pins will depend of the board. As an example that may help (as it has many pins routed to its edge connector), you could refer to the Voipac i.MX53 SODIMM Module from SOS Electronic:

Hope this will be useful for you.
Best regards!

Thanks Carlos:

A lot of modules have several shared pins 32-bit GPIOs that could be used if they made it to the connectors of the evaluation board, that the module is plugged into.   A simple evaluation board with a lot of connectors pins, would be ideal.

Hi,

On the following link you could find a list of boards from third parties. You could evaluate these options and verify if some of them work for your needs, or you will need to design your own board according with your requirements:

Hope this will be useful for you.
