The W65C134S is a feature rich 8–bit microcomputer based on the W65C02 with an advanced (originally designed for life support) Serial Interface Bus (SIB) token passing local area network for multi–W65C134S processor systems. The W65C134S has a full external memory bus (8–bit data and 16–bit address bus) for flexible system design. This MCU has an embedded debug monitor ROM with a library of routines that can help you reduce development time.
