The 80C152, which is based on the MCS
É
-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 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 a single board.
