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 ?
PS:
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 :)
