CS82C52Z

Overview

The CS82C52Z is a single-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by Renesas Electronics. Designed for serial communication applications, it operates within a supply voltage range of 4.5 V to 5.5 V, with a nominal operating voltage of 5 V. The device supports data rates up to 1 Mb/s and draws a maximum operating supply current of 4 mA. It functions reliably across an ambient temperature range from 0°C to +70°C. The component is housed in a 28-lead Plastic Leadless Chip Carrier (PLCC-28) package suitable for surface mount technology.

Feature Summary

• Provides asynchronous serial data transmission and reception capabilities via a dedicated UART interface.
• Integrates a baud rate generator for flexible clock configuration without external timing components.
• Ensures compatibility with standard RS-232 signaling protocols for peripheral connectivity.

Applications

• Serial communication interfaces in industrial control systems
• Data acquisition modules requiring asynchronous data transfer
• Embedded system peripherals connecting microcontrollers to external devices

Procurement Notes

Verify the specific ordering suffix against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental declaration. Check for End-of-Life notices or Product Change Notifications prior to finalizing procurement plans to ensure long-term availability.

Selection Notes

Select this component when a single UART channel with integrated baud rate generation is required for 5V logic systems. Ensure the design accommodates the PLCC-28 footprint and SMD mounting requirements. Verify that the application environment remains within the specified 0°C to +70°C operating temperature range and does not exceed the 5.5 V maximum supply voltage limit.

Part Context

The CS82C52Z belongs to the 82C52 family of UART interface ICs produced by Renesas Electronics. This series provides standardized asynchronous communication solutions compatible with various microprocessor architectures. The component serves as a bridge between parallel bus systems and serial data streams, facilitating reliable data exchange in embedded environments.

Replacement Considerations

Consult official cross-reference guides for functionally equivalent UART controllers. Verify pinout compatibility and electrical specifications before substituting with alternative part numbers from other manufacturers.
