microcontroller and USB

[ronzam2002]

How can I interface the USB(universal serial bus) with the 8051 mcu? Can you give me a sample circuit which includes a microcontroller and USB...:?:

try ftdi chip from www.ftdi.com

have a look at www.cypress.com They have a cpu with an 8051 core that has built in hi speed USB

Hi,

Microcontroller may not have direct USB interface, because USB is differential signalling. You can interface with serial port with additional glue logic which convert USB to serial port signals.

i think 8051 can't interface via usb port

Hello,

You just require to study whats suits you.
I mean which is the type of interface you want with 8051.
Here are a few options:
1. Use FT232R connect to 8051 using MCU Serial Port
2. Use FT245BM connect to 8051 using a 8-bit MCU port
3. Have a Cypress Micro with inbuilt USB
4. Use a PIC18F4550 and implement the Microchips application note

I hope that now you have some clarity on your options.
Let me know if you want any help in any of the above choices. Since I have used all of them.
