ID82C52

Overview

The ID82C52 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 an operating supply current of 4 mA. It is housed in a 28-lead Ceramic Dual In-line Package (CDIP-28) suitable for through-hole mounting. The component functions across an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Integrates UART functionality with a built-in baud rate generator for asynchronous serial communication.
• Supports high-speed data transmission rates up to 1 Mb/s using CMOS technology.
• Compatible with standard RS-232 signaling protocols for peripheral interfacing.

Applications

• Industrial control systems requiring robust serial communication interfaces.
• Embedded systems utilizing 8-bit or 16-bit microcontrollers.
• Peripheral devices needing reliable asynchronous data transfer.

Procurement Notes

Verify the specific manufacturing lot and date code upon receipt, as this component may be sourced from legacy production lines. Confirm that the CDIP-28 package matches the footprint requirements of the target PCB design. Ensure compliance with relevant environmental regulations if RoHS exemption is required for the specific application context.

Selection Notes

Select the ID82C52 when a ceramic DIP package is mandatory for mechanical stability or thermal performance in harsh environments. Consider the 4.5 V to 5.5 V operating range against system power rails. Evaluate the 1 Mb/s maximum data rate against bandwidth requirements. Compare the through-hole mounting style against surface-mount alternatives like the CS82C52Z if space constraints allow.

Part Context

The ID82C52 belongs to the 82C52 series of UART controllers, representing a CMOS evolution of earlier TTL-based serial interface chips. It serves as a bridge between parallel microprocessor buses and serial communication lines. The ceramic packaging distinguishes it from plastic variants, offering higher reliability for industrial and military-grade applications where long-term stability is critical.

Replacement Considerations

The CS82C52Z is a pin-compatible surface-mount alternative in PLCC-28 packaging, though it has a narrower commercial temperature range (0 °C to +70 °C). For extended industrial temperatures, verify availability of other CDIP variants such as MD82C52-B, which supports -55 °C to +125 °C.
