The W65C02SXB is a seminal single board microcomputer for developing educational and industrial strength microcontrollers. As such, the W65C02SXB has become an Engineering Development System based around the world renowned W65C02S 8-bit microprocessor. With its vast I/O provided by the on board W65C22 VIA, W65C21 PIA, and W65C51 ACIA peripheral ports the W65C02SXB provides the user with easy access to the vast flexibility in microcontroller design possibilities using our Addressable Register Architecture (ARA). The addition of the XBus allows for expansion beyond the standard on board peripherals by providing full Data Bus, Address Bus and Control Signal access. The W65C02SXB has a debugging connection to the WDCTools. Code can be developed and the binary output can be downloaded to the board through the TIDE port interface and monitor firmware. Since the W65C02S is upwards compatible with the W65C816S, your W65C02SXB applications can be easily ported to the W65C816SXB. Designed and Developed in the USA
