Alright! Talk about timing 8) The price in those sort of adevertisements is almost always their bulk quantity pricing. > It's an 8-bit microcontroller including RAM (128 or 256 bytes depending > on the part), EPROM (4Kb or 8Kb), a USB serial engine, and a transceiver. > It has a clock-doubler and "instant-on" low-power features.

Number of I/O's refers to the number of uncommitted external pins available for generic I/O. You need 6 for a 3-button rodent; if you're patient enough you can do absolutely anything with 10 (but you need extra logic; more I/O's just saves you space and parts count). I'll have to look into these guys; this is pretty hot stuff. > The also advertise a development system is $495 including an emulator, > assembler, debugger, software for mouse/joysticks, and a USB code > library.

US$500 is pretty average for a full development kit; there's probably a cheaper option that just gives you the asembler and leaves you to build the programming hardware yourself. Do they mention anything about reprogrammable parts? The $1 component is going to be an OTP in a plastic package I expect; an EEPROM or windowed part would be useful for development. > For the record, I'm not am employee, customer, a contractor, or in any > way affiliated with Cypress.
