MCU recommendation for SDRAM + Zio header

dish12

Hi,

 

Can anyone recommend a development board that has ZIO headers and on-board SDRAM as well? I can't seem to find any.

I have some other requirements as well:

-> Needs to have a system clock > 180Mhz

-> Advanced DMA Features

-> Needs to have on chip ADC and DAC 

-> Nice to have ethernet support.

 

Thanks in advance,

Disha

Distributors often also have parametric search facilities...

You mean the double-row Arduino headers? Like this:

That's a feature of the board - not the MCU.

They are found only (I think) on the Nucleo-144 boards.

Again, that would be a feature of the board - rather than the MCU.

Hello,

That depends also on the application needs and the performance 

SDRAM is available only on some Eval boards and some DISCO boards.

If you need a ZIO connector I can suggest STM32F429-DISCO board that has an onboard SDRAM + male ZIO connectors.

Does it?

I thought Zio meant the double-row headers on the Arduino layout ?

That disco just has standard 0.1" two-row headers ?

There is no mention of "Zio" in the STM32F429-DISCO manual:

That depends on what the OP means by "ZIO". I think he needs that most of IOs are available on the board. 

For the ZIO mentioned in the user manual, I don't think there is a board fitting: Arduino ZIO + SDRAM.

And I think STM32F429-DISCO fits most of the OP requirements.

Indeed, the OP may be misusing it.

But what ST means by it is the doubled-up Arduino pattern - yes?

I don't have the info :)
