		WDC was founded in 1978 by co-holder of the MOS Technology 6502 patent, Bill Mensch, himself a former MOS employee.
		In addition to the actual microchips, WDC offers chips designs in the form of IP cores to be used inside other chips (like ASICs), and provides ASIC and embedded systems consulting services revolving around their processor designs.
		The WDC 65816 (also: 65C816), a 16-bit microprocessor CPU developed by the Western Design Center (WDC), is an expanded and compatible successor to the venerable MOS Technology 6502.

		The WDC 65816 (also: 65C816), a 16-bit microprocessor CPU developed by the Western Design Center (WDC), is an expanded and compatible successor to the venerable MOS Technology 6502.
		The 65816 was second-sourced by GTE, Sanyo and a couple of other semiconductor companies from the mid-to-late 1980s to the early 1990s.
		The 65802 was produced by WDC and GTE during the mid-to-late 1980s and early 1990s.

		The WDC W65C816 microprocessor is a 16-bit enhancement to the 8-bit 6502 that is fully backward compatible.
		However, all the 65816 emulators available tend to not be portable.
		KEGS has a 65816 emulator that is nearly impossible to isolate from the Apple IIgs core logic, for example.

	MOS Technology 6502 - Wikipedia, the free encyclopedia
		The Western Design Center designed and produced the 65816 processor, a 16-bit successor to the 65C02 as well as a hybrid offshoot called the 65802 which was a 65816 with a 64 KB address space in a 65(C)02 pin-compatible package.
		Mitsubishi (now Renesas Technology) made a line of 16-bit microcontrollers with an architecture very similar to the 65816, though it was not 100% compatible.

	[No title]
		WDC developed the 16-bit successor of the 65C02, which did not implement the additional instructions of the 65SC02.
		On the 65816, the opcodes of TAB and TBA stand for TCD and TDC (or TAD/TDA)[8], that is Transfer [16-bit] Accumulator [C] to Direct Page Register D (and the other way round).
		The 65CE02 has been designed far after the WDC 65816 had appeared, and because these commands look quite similar, it is quite likely that B stands for the bank the zero page is stored in, thus meaning the 65CE02 would also have direct page functions just like the 65816.

	W65C816S 16-bit Microprocessor
		WDC's high volume production proven 65xx brand microprocessor family of manually designed GDSII hard cores are highly optimized cores that are small and low power and therefore an excellent choice for low power System-on-Chip (SoC) ASIC microcontroller designs.
		The WDC W65C816S 8/16-bit microprocessor is software compatible with the 8-bit NMOS and CMOS 6500-series predecessors.
		To aid in system development, WDC also provides the 65xx Development Tools suite, developer boards and design kits.

	the 65816, WDC and Atari's proposed 16bit version of 6502 - AtariAge Forums
		who was it, I ask because, I understand that the 65816 and variations for the WDC 65xxx family of processors were the only commercially released and recognised 16bit versions of the 6502 processor officially released and therefore WDC were the only 'recognised' manuf.
		If the 65816 had come out in 1980 or 1981, then maybe it would have gained more mindshare, but it came around rather late in the game.
		The 65816 was used in the SNES, and given its immense popularity, I'd consider the chip to be wildly successful.

	6502.org :: View topic - MMU units for 6502 and 65816
		I started wondering this morning while thinking about how to tackle the operating system for the WDC 65816 project my friends and I are working on about memory protection and management.
		Note that this requires fairly intimate knowledge of the processor internals, as it requires various bits to be set/reset to force the processor to restart the instruction after the exception is handled and the processor state is reloaded.
		I thought about how to add an MMU to the 65816 once, and if I remember correctly, it has a bug which will prevent it from working properly.

	Western Design Center (WDC) Home of the 65xx Microprocessor
		Annual volumes in the hundreds (100’s) of millions of units keep adding in a significant way to the estimated shipped volumes of five (5) to ten (10) billion units.
		The WDC 65xx system bus, as shown in the system block diagram below, is highly flexible and effective whether on PCB’s with our Chips or on ASIC microcontrollers with our Cores.
		The WDC 65xx synchronous control bus enables asynchronous processing events to be interfaced with a minimum of logic and therefore minimizes cost and performance delays.

	6502-65816 Adapter Board
		There has been some interest in using a WDC 65C816 processor in a system that was designed for a 6502.
		IC3 and IC4 are used to create the two-phased clock output PH1 and PH2 that the 65816 does not generate.
		By using SOIC versions of IC2,3,4, and the TQFP version of 65816, it became possible to squeeze the entire circuit into the size of a DIP40.

		Fast Eddie's core module is a speedy 65816 emulator, code-named "hot bird", running at 3Mhz and up (your mileage may vary).
		It supports the entire command set of the WDC 65816® in native and emulation mode (some restrictions apply).
		This module is surrounded by other emulated hardware components such as the n-sonic sound engine, the CleverPort disk controller, the Giga II compatibility module, and the Graffiti video blitter.
