The 80C152, which is based on the MCSÉ-51 CPU, is 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 applica- tions. 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 modulari- ty of hardware and software designs. All of theseÐcost, network parameter and real estate improvementsÐ apply to 83C152 serial links between boards or systems and 83C152 serial links on single board.
