Ubicom / Parallax PIC SX28A Microcontroller
- 75Mhz max clock & 75 MIPS (1 instruction per clock)
- 28 pin DIP package, ideal for prototyping.
- 20 TTL/CMOS/Schmitt I/O pins
- 136 bytes of SRAM.
- 2K EEPROM program memory.
- Fast IRQ handling.
- Functionally very similar to the PIC16C54
- Instruction set much like the PIC range (though Ubicom use different mnemonics)
- Can use an internal RC oscillator, crystal/ceramic resonator or ext. clock drive.
- DIY programmer circuit available. ("Fluffy 2" - see link below)
- DIY programmer supported by ICprog (set hardware to "Fluffy programmer")
