CS82C50A-5

Overview

The Harris CS82C50A-5 is a high-performance CMOS Asynchronous Communication Element (ACE) and Universal Asynchronous Receiver/Transmitter (UART). It operates on a single supply voltage ranging from 2V to 5.5V with a maximum quiescent current of 2 µA. The device supports surface mount mounting in a 44-PLCC package measuring 16.58x16.58 mm. It functions within an operating temperature range of -40°C to 125°C.

Feature Summary

• Integrates UART and Baud Rate Generator functionality into a single programmable component
• Utilizes advanced CMOS process for low power consumption and high performance
• Supports RS232 interface communication protocols

Applications

• Serial data transmission systems
• Microcontroller peripheral interfaces
• Embedded communication modules

Procurement Notes

Verify the specific manufacturer source, as documentation references both Harris Corporation and Intersil Corporation. Confirm the package type matches the 44-PLCC specification and ensure the voltage and temperature ratings align with system requirements before procurement.

Selection Notes

Select this component when a compact, low-power UART solution is required for embedded applications. The wide operating temperature range and single-supply operation make it suitable for diverse industrial environments. Ensure the design accommodates the 44-pin PLCC footprint.

Part Context

This part belongs to the 82C50A series of Asynchronous Communication Elements. It serves as a bridge between parallel microprocessor buses and serial data streams, replacing discrete logic solutions with a single integrated circuit for simplified board design.

Replacement Considerations

Check datasheets for pinout and electrical compatibility with other 82C50 variants or generic UART ICs. Verify that alternative components support the same 44-PLCC package and voltage ranges.
