IDEA: ARM stamp SBC ?

rziak · 2005-10-23T03:03:14+00:00

Hello,I wonder if anyone makes something like Parallax did with PIC, butpopulated with ARM ?Anyone selling DIP40 device with ARM and FPGA and ethernet? Withbootloader, RTOS and interpreter for fast prototyping?Digi has Connect ME device, but it is not DIP and anly 5 I/Os and UARTfrom the ARM device is accessible. Lantronix has Xport with 3 I/O andUART and they are releasing new Xport AR in November with 3 UARTs andaround 13 I/Os (if I am not mistaken).Did anyone put together an SBC size of DIP40 with modern embeddedcontroller? Or maybe there is an open design or open source projectruning?Well, in case there is not, I estimate the parts for such device may bearound $10 for ARM with integrated SDRAM/FLASH and $10 for FPGA plusfew $ for PCB, labour, connectors. The ethernet is a nice connectivityoption but definitely not a must.The prototyping could have RS232/TTL converter, DIP40 socket, 1 or 2A/D, few LEDs and prototyping area.With Lua interpreter the prototyping would be a breeze.I will apreaciate ideas, links, advices, concerns and parts suggestions(high integration low pin-count types).Thanks

What do you mean by phantasy? There are actual soft ARM cores in 200K, PPC cores in 300K FPGAs. What do you think the micro manufacturers use for prototypes?

1M gates FPGA is mid-range. 5M gates can be yours, if you send us a cashier check.

These are also nice. Thank you!

I agree, there seems to be tendency to overkill. The whole ARM core is

30k transistors; 1mil gates FPGA for $hundreed(s) just to immitate ARM core for 5 bucks ... nonsense

Anyone selling an ASIC, something like AT91SAMX but bundled with PHY ?

Impossible to do it in 30k. Unreasonable to buy FPGA with less than

200k. You are the one asking for FPGA. Have you find any ARM with FPGA for less than $100? You are not only asking for ARM, but ethernet, Sdram, CF and custom FPGA gates.

Have you guys really look into the FPGA market?
