P80C152JA

Product Summary

The P80C152JA is a highly integrated single-chip 8-bit microcontroller which is based on the MCS-51 CPU, 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 P80C152JA 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-toserial and serial-to-parallel converters. The P80C152JA contains, in silicon, all the features needed for the serialto- parallel conversion. Other P80C152JA 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 theseDcost, network parameter and real estate improvements-apply to 83C152 serial links between boards or systems and 83C152 serial links on a single board.
