W65C02S8P-14

Product Details

__

The W65C02S is a low power cost sensitive 8-bit microprocessor. The W65C02S is a fully static core and the PHI2 clock can be stopped when it is in the high (logic 1) or low (logic 0) state. The variable length instruction set and manually optimized core size makes the W65C02S an excellent choice for low power System-on-Chip (SoC) designs. The Verilog RTL model is available for ASIC design flows. WDC, a Fabless Semiconductor Company, provides packaged chips for evaluation or volume production. To aid in system development, WDC provides a Development System that includes a W65C02DB Developer Board, an In- Circuit Emulator (ICE) and the W65cSDS Software Development System,

Features of the 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
