[EE] Popular general purpose USB MCUs for hobbyists other than PIC by Chen Xiao Fan .

I know there are some other USB MCUs other than PIC. For example, Silicon Labs C8051F320/321 seem to be nice USB MCU (they have US$11 demo board for sale and the US$29 demo kit for C8051F064 uses this USB MCU as the programmer/debugger). However the packaging is not so friendly to hobbyists (LQFP32 and MLP28). Philips LPC214x seem to be a nice family of USB MCUs. The package might be a problem (LQFP64). It is a bit strange that the Atmel USB MCUs are not so popular judging from Google search results even though their 8051 and AVR are quite popular. I am not so familiar with other family of MCUs like the Cypress PSoc and their USB MCUs but quite some of them are not really general purpose MCUs. Regards, Xiaofan
