The W65C816SXB Engineering Development System is a robust single-board computer designed for both educational purposes and industrial-grade microcontroller development. At its core is the renowned W65C816S 8/16-bit microprocessor, complemented by integrated peripherals including the W65C22 Versatile Interface Adapter (VIA), W65C21 Peripheral Interface Adapter (PIA), and W65C51 Asynchronous Communications Interface Adapter (ACIA). This configuration offers extensive I/O capabilities for Sensing, Processing, Communicating, and Actuating (SPCA). The board features an XBus expansion interface, granting full access to the Data Bus, 24-bit Address Bus, and Control Signals, thereby enabling seamless integration of additional peripherals.
Developers can efficiently create and upload code via the TIDE port interface, supported by onboard monitor firmware. Notably, the W65C816S's backward compatibility with the W65C02S ensures a smooth transition for applications migrating from the W65C02SXB platform. The W65C816SXB stands as a reliable and flexible solution for a wide range of microprocessor applications.
