Quick SBC with 16-bit AD and Ethernet ?

Started by Dave Nadler December 1, 2011
Hi Folks - I'm looking at a quick project that needs:
- 16-bit AD data acquisition,
- Ethernet connectivity
- modest processing requirements (32-bits best)
- ideally contemporary ARM supported by lots of
  toolchains RTOS etc.
I'd love to use Actual Fusion (but only 12 bits)
or Cypress PSoC (but no Ethernet).
Quick look around shows lots of 12-bit solutions.
Tern has high res AD but old x86 16-bit CPU.
Don't mind a two-board soluion but looking for
minimal fuss to get something going...

Any favorite tools you can suggest ?

Thanks in advance,
Best Regards, Dave

well, x86 again but, WinSystems has boards with quite a bit of I/O and 'horsepower'. Linux and even romdos available, boot from cflash, lattice, customizable BIOS, daughter boards (PCIe IIRC), etc.

The Kinetis M60 series from Freescale has two independent 16-bit ADCs and ethernet However,they only spec 14.5 Bits noise-free. Controlling the noise with 16-bit ADCs on the same die as fast logic is still a problem. Depending on your speed requirements, you might be OK with some oversampling and digital filtering.

I've been a fan of IAR EWARM for many years. It's expensive ($5K), but support is good and they have chip-specific headers for a lot of the ARM chips.
