W65C02RTL: 8-Bit 65xx Microprocessor

IP Target Vendor: 
Lattice
IP Type: 
Design
IP Category: 
Embedded Processing
IP Description: 

"The W65C02RTL Soft Core from The Western Design Center is a general purpose 8-bit Microprocessor Core. The core was designed to emulate the available W65C02C GDSII Hard Core. This characteristic makes the soft core ideal in FPGA prototyping systems for ASIC designs that will use the hard core, while remaining flexible for strictly FPGA designs. The core is available with a serial interface for WDC’s development tools.

Features
8-bit Data Bus
16-bit address bus provides access to 65,536 bytes of memory space
69 Instructions
212 Operation Codes (OpCodes)
16 Addressing Modes
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 enable synchronization with external events
Variable length instruction set enables smaller code optimization over fixed length instruction set processors. This results in low power as well
Hardware Breakpoint for on system debugging
UART configured for serial interface to development tools"
