The W65C134SXB is based around the W65C134S which is a feature rich 8–bit microcomputer based on the W65C02 microprocessor with an advanced (originally designed for life support) Serial Interface Bus (SIB) token passing local area network for multi–W65C134S microcontroller systems. The full external memory bus (8–bit data and 16–bit address bus) allows for flexible system design. This MCU has an embedded debug monitor ROM with computer terminal interface a library of routines that can help you reduce development time and optimized for designing human exo and endo robotic functions, for examples of microcontrollers that can be developed from the W65C134S microcomputer. Designed and Developed in the USA
