CP82C50A-5Z

Overview

The CP82C50A-5Z is a CMOS Universal Asynchronous Receiver/Transmitter (UART) manufactured by Renesas Electronics Corporation. It provides a single full-duplex asynchronous communication channel and is housed in a 40-pin Plastic Dual In-line Package (PDIP). The device operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 1.5 Mbit/s. It features an internal baud rate generator, programmable stop bit lengths, and parity generation/checking capabilities. The component is designed for compatibility with standard microprocessor buses and includes interrupt request outputs.

Feature Summary

• Provides a single full-duplex asynchronous serial communication interface
• Integrates an internal programmable baud rate generator
• Supports hardware flow control via Request-to-Send and Clear-to-Send signals
• Includes programmable parity generation and checking logic

Applications

• RS-232 serial communication interfaces
• Modem control circuits
• Microprocessor-based system serial ports
• Industrial equipment serial data links

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Procurement should focus on verifying stock availability from authorized distributors or surplus suppliers. Buyers must confirm that inventory represents genuine Renesas products and check for any specific handling requirements associated with legacy semiconductor components before finalizing acquisition.

Selection Notes

Engineers selecting this part should verify compatibility with existing 5V logic levels and bus timing requirements. The PDIP-40 package requires through-hole mounting space. Designers must ensure that the application does not require higher data throughput than the 1.5 Mbit/s limit or additional UART channels, as this is a single-channel device. Alternative solutions may be necessary if surface-mount packaging is preferred.

Part Context

The CP82C50A-5Z belongs to the 82C50 family of UARTs, which are CMOS versions of the classic 8250/16450 architecture. This series was widely used in personal computers and industrial controllers for serial port implementation. The '5Z' suffix typically denotes a specific manufacturing variant or lead-free processing status within the Renesas product line.
