Mostly, that's because those parts are designed for use in very high- volume applications like mice and keyboards, so the cost of an emulator and/or a few tubes of OTP parts is trivial. If you're a hobbyist who wants to make a USB device, though, I would HIGHLY recommend Cypress's full-speed "EZ-USB" micros over the low- speed parts. Low-speed USB is dumb; full- and high-speed USB (especially with the "smart" SIE in the EZ-USB parts) is MUCH nicer. The EZ-USB parts are RAM-based, so you only need to buy one. Code is downloaded to them either over the USB connection or from a serial EEPROM. An EZ-USB development kit is available from Cypress for around $400; if that's too expensive, there are a number of third-parties who sell <$100 EZ-USB development boards. -Andy === Andrew Warren -- aiw@cypress.com === Principal Design Engineer === Cypress Semiconductor Corporation === === Opinions expressed above do not === necessarily represent those of === Cypress Semiconductor Corporation -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
