CP82C52Z

Overview

The CP82C52Z is a high-performance programmable Universal Asynchronous Receiver/Transmitter (UART) and Baud Rate Generator (BRG) manufactured by Renesas Electronics Corporation. It integrates UART and BRG functions on a single chip using advanced CMOS technology. The device supports asynchronous data rates up to 1 Mb/s with a 16 MHz clock frequency. It operates on a single +5V power supply with a maximum voltage of 5.5 V and a minimum of 4.5 V. Typical operating current is 4 mA. The component features one channel, utilizes a PLCC-28 package for surface mount installation, and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates UART and Baud Rate Generator functions on a single chip
• Supports microprocessor bus oriented interface compatible with 80C86 systems
• Provides interrupt mode with mask capability and line break generation/detection
• Accepts crystal or external clock input for flexible baud rate configuration

Applications

• Microprocessor-based serial communication systems
• Modem interface circuits
• Industrial control equipment requiring RS-232 compatibility

Procurement Notes

Verify the specific manufacturer suffix and RoHS compliance status against official Renesas documentation before procurement. Confirm that the PLCC-28 package matches the target PCB footprint requirements. Check for any product discontinuation notifications or end-of-life declarations from the manufacturer to ensure long-term availability for production needs.

Selection Notes

Select this component when a single-chip solution for UART and baud rate generation is required for 80C86-compatible systems. Ensure the design accommodates a 16 MHz clock source for maximum data rate performance. Verify that the 0°C to +70°C commercial temperature range meets the environmental conditions of the intended application environment.

Part Context

The CP82C52Z belongs to the 82C52 series of CMOS Serial Controller Interfaces originally developed by Intersil and now produced by Renesas Electronics. This series represents a modernized CMOS version of legacy TTL UART components, offering lower power consumption while maintaining functional compatibility with standard microprocessor buses.
