Western Design Center 65xx Engineering Development Systems

Western Design Center 65xx Engineering Development Systems are educational and industrial-strength Engineering Development Systems based around world-renowned 8/16-bit microprocessors. The W65C816SXB and W65C02SXB feature vast I/O provided by the onboard W65C22 VIA, W65C21 PIA, and W65C51 ACIA peripheral ports. The 816 SXB offers easy access to extensive flexibility in design possibilities using Addressable Register Architecture (ARA). The addition of the XBus allows for expansion beyond the standard onboard peripherals by providing full data bus, address bus, and control signal access. The Western Design Center W65C134SXB and W65C265SXB feature proven functionality for applications in production that require in-system diagnostics featuring internal system monitor ROM. Suppose the user needs robust math for applications in sensing, such as pressure, temperature, revolutions per minute, flow monitoring and control, variable climate control, or other systems for scientific, automotive, communications, home appliance/automation. In that case, the user will benefit from the ANSI Standard C compiler.
