Arduino compatible device with 64MB or more RAM

Other Hardware 3rd Party Boards

I'm considering creating a audio sampler, and to store all audio, I need RAM of atleast 64MB (megabytes).
Is there such a thing available or should I consider something that needs a couple of seconds to boot up?

That is the domain of a Raspberry Pi or similar tier of single board computer. That is orders of magnitude more than any arduino compatible device I am aware of.

I changed the post to 64MB, as I saw that the ARM "PrimeCell MultiPort Memory Controller" works with up to 512Mbit of SDRAM, amazing!

Doesn't change my answer. Your application sounds like it involves large amounts of data, and realtime handling of audio. That's not a good fit for Arduino.

Found out that they can handle 2 banks x 256MByte each! Thats fantastic.

DrAzzy: Have you seen the 400 mhz M7 MCU? Its not exactly an Arduino UNO.

This unit runs on a couple of 250 mhz coldfire mcus, also with external RAM:

Neither CM7 nor Coldfire is supported by any Arduino core that I know of.
The Raspberry Pi is also an ARM chip, and it comes with 512M or 1G of RAM, these days.

It looks like the sam3x8e processor used by Due could address of to 8 banks of 16MB memory chips.

I just meant performace-wize.

Can I use a raspberry pi with only encoders, switches, and a couple of 128x64 pixel lcd screens? (Just like an mcu). The question might seem rude, but I'm serious, as I don't know. Also, there is the desktop computer-style boot-up time, no?

Sure, why not?

In case of FreeRTOS or bare metal programming - raspberry Pi boots instantly.
