I would not call that Industrial standard, only a handful of companies are able to do that (Silabs, FTDI, etc), majority of the companies, even some other MCU companies with better USB expertise (NXP, Atmel, ST, etc) will still require you to use Crystal. > Industry temp (-40-85C) version FX2lp almost cost doubled its > commercial (0-70C) version. That is one reason why people are having more interests in the offerings from other MCU vendors. Yes EZ-USB may be easier in terms of USB programming and have the clear advantage of longer time in the market. But now more and more leading USB experts are looking at Microchip MCU parts, for example, Jan Axelson. If you look at the Microchip forum USB section, it is very active and people are having success developing successful product with Microchip USB MCUs. http://www.microchip.com/forums/tt.aspx?forumid=102 -- Xiaofan http://mcuee.blogspot.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
