W65C02S

· 8-bit data bus
· 16-bit address bus provides access to 65,536 bytes of memory space
· 8-bit ALU, Accumulator, Stack Pointer, Index Registers, Processor Status Register
· 16-bit Program Counter
· 69 instructions
· 16 addressing modes
· 212 Operation Codes (OpCodes)
· Vector Pull (VPB) output indicates when interrupt vectors are being addressed
· WAit-for-Interrupt (WAI) and SToP (STP) instructions reduce power consumption
    decrease interrupt latency and provide synchronization with external events
· Variable length instruction set provides for lower power and smaller code optimization
    over fixed length instructionset processors
· Fully static circuitry
· Wide operating voltage range, 1.8+/- 5%, 2.5+/- 5%, 3.0+/- 5%, 3.3+/ - 10%, 5.0+/- 5% specified
· Low Power consumption, 150uA@1MHz
