Coco,

When I fix my car, I have a tool box with wrenches, screwdrivers, hammer and others.

To remove a nut, I use a wrench. If I try to use a hammer, the nut does not come off and then it is broken.

The SX uC is a tool. If you have the rigyt kind of problem and you know how to use this tool it can work very well. It will not work well for many jobs. 

It will not work well to replace a PC, it will not work well with USB. There are many other uC that will do these thigs much better.

Microchip (another manufacturer) makes a family of uC called PIC. More PIC uCs are sold every year than any other uC family.  Some PIC have less than 1K ROM, some have 128K ROM. Some have only 8 pins, some 80 pins. Different part are suitable for differnt tasks.

Senix/Ubicom designed the SX to be very much like the PIC (so much so that Microchip sued them - and lost). The difference was that the PIC executes 1,000,000 instructions per second and the SX at least 50,000,000.

Most PIC uCs like almost all uCs have hardware peripherals built in: timers, UARTs, A/D and D/A etc. The SX has only simple timers and nothing else. Instead of using hardware, clever programmers can use the high speed of the SX to make peripherals in software.

If you have a project that needs standard peripheral devices and does not need exceptional spped, I WOULD STRONGLY RECOMMEND LOOKING AT A DIFFERENT uC.

If you need high performance, low cost, and customized peripherals, AND you are very clever programmer who can solve your own problems with minimal support, try the SX. It can be a lot of fun and very rewarding.
