Answer: IT DEPENDS.
If you want to do High-Speed transactions, ditch the 89C51 and use the Cypress EZ-USB FX2 family. If you can live with full speed, the SiLabs C8051F320 and F340 work well. if you want your device to look like a standard RS-232 interface, then the FTDI or an SiLabs chip might be the ticket. Furthermore, depending on what you want to do, you might need to add some amount of "other logic" to fulfill your dreams! -a |
