CS82C50A-596

Overview

The Intersil CS82C50A-596 is a high-performance CMOS Universal Asynchronous Receiver/Transmitter (UART) and Baud Rate Generator. It operates within a voltage range of 4.5V to 5.5V and supports data transmission rates up to 625Kbps. The device features a single UART channel and is housed in a 44-pin PLCC package. Designed for asynchronous communication, it includes programmable baud rate generation and double-buffered data registers to facilitate efficient serial data handling in microprocessor systems.

Feature Summary

• High-speed CMOS technology ensures low power consumption while maintaining performance comparable to NMOS equivalents.
• Integrated baud rate generator provides flexible clocking options for various serial communication standards.
• Double-buffered data registers simplify software interface design by preventing data loss during read/write operations.

Applications

• Microprocessor-based serial communication interfaces
• Industrial control system data links
• Embedded computer peripheral connectivity

Procurement Notes

Verify the specific suffix '596' against the manufacturer's current product lifecycle status, as Intersil has been integrated into Renesas Electronics. Confirm that the 44-pin PLCC package availability aligns with current manufacturing capabilities. Ensure compatibility with existing board layouts requiring this specific footprint and pin configuration before procurement.

Selection Notes

Select the CS82C50A-596 when a robust, low-power UART solution is required for 5V logic systems. Its compatibility with standard microprocessors makes it suitable for legacy system upgrades or new designs needing reliable serial I/O. Consider the 44-pin PLCC package constraints regarding PCB space and thermal management during the selection process.

Part Context

The CS82C50A series belongs to the 82C50 family of Asynchronous Communication Elements, representing the CMOS evolution of earlier NMOS devices. This lineage ensures pin and functional compatibility with industry-standard components while offering improved power efficiency. The component reflects Intersil's focus on high-reliability analog and mixed-signal solutions prior to its acquisition by Renesas.

Replacement Considerations

Direct substitutes may include other CMOS UARTs from Renesas or compatible manufacturers supporting similar baud rates and pinouts. Verify electrical specifications and package dimensions to ensure seamless integration without redesigning the host circuit board.
