From: jaipal on 25 May 2010 10:28 My Dear Sir, We are interested in the device which can convert USB to local bus. The local bus is 16 bit wide, do you have device to support the following configuration: -------------------- | | ==> Address Bus 20 bits USB <==> | USB to Local Bus | <==> Data Bus 16 bits | | <==> Control Bus -------------------- Can you suggest any particular device(s) part number and associated RDK. With regards. B. Jaipal Reddy --------------------------------------- Posted through http://www.EmbeddedRelated.com

Yes. Just about any microcontroller with USB will do the job. My current favorite is the STM32. I've successfully used the IAR Embedded Workbench on that device.

Yes, any single chip USB micro will do. But with 36+ I/Os, it will have to be a big chip. You can use a small USB chip and one or more CPLD for demultiplexing. We are planning on Atmega32u2 + XC9536XL(s) for our project.

Jaipal Reddy > > --------------------------------------- > Posted throughhttp://www.EmbeddedRelated.com FTDI ft2232 (and probably a few others from them) has a mode where it acts like a 8051 microcontroller bus Netchip (now part of PLX) has a couple of parts that do USB-local bus you could probably use a USB-PATA converter if you could live with only 3 address lines cypress makes some chips they call 'west bridge' chips a google search for 'usb local bus' returned several other hits (hint hint) |
