The 80C152, which is based on the MCSÉ-51 CPU, is a highly integrated single-chip 8-bit microcontroller designed for cost-sensitive, high-speed, serial communications. It is well suited for implementing Integrated Services Digital Networks (ISDN), emerging Local Area Networks, and user defined serial backplane applications. In addition to the multi-protocol communication capability, the 80C152 offers traditional microcontroller features for peripheral I/O interface and control.Silicon implementations are much more cost effective than multi-wire cables found in board level parallel-to serial and serial-to-parallel converters. The 83C152 contains, in silicon, all the features needed for the serial to– parallel conversion. Other 83C152 benefits include: 1) better noise immunity through differential signaling or fiber optic connections, 2) data integrity utilizing the standard, designed in CRC checks, and 3) better modularity of hardware and software designs. All of these cost, network parameter and real estate improvements apply to 83C152 serial links between boards or systems and 83C152 serial links on a single board.
