CDP6872E

Overview

The CDP6872E is a low-power crystal-controlled oscillator manufactured by Harris Corporation, now part of Renesas Electronics. Designed for single-supply operation, it supports frequency ranges from 10 kHz to 10 MHz and operates within a voltage range of 2.0 V to 7.0 V at 32 kHz. The device requires only an external crystal for functionality and features a disable mode that places the output in a high-impedance state to minimize power dissipation. It is housed in an 8-lead plastic DIP package and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Low power consumption with supply current of 5 µA at 32 kHz and 130 µA at 1 MHz
• Wide operating frequency range from 10 kHz to 10 MHz
• Single supply operation compatible with 2.0 V to 7.0 V
• High stability over wide operating voltage and temperature variations

Applications

• Battery-powered circuits requiring extended operational life
• Remote metering systems with limited power availability
• Embedded microprocessor clock sources

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'E' corresponds to the -40°C to +85°C temperature grade and PDIP8 package. Check for RoHS compliance status as legacy components may have varying environmental certifications depending on production batch dates.

Selection Notes

Select the CDP6872E when a programmable crystal oscillator is needed for low-power embedded applications. Ensure the external crystal matches the desired frequency within the 10 kHz to 10 MHz range. Verify that the system voltage falls within the 2.0 V to 7.0 V operating window. Consider the disable pin functionality if power management during standby modes is required.

Part Context

The CDP6872 series was originally developed by Harris Semiconductor before being acquired by Intersil and subsequently Renesas Electronics. This component belongs to a family of low-power oscillators designed for battery-operated devices. The E suffix typically denotes the extended industrial temperature range variant.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternatives based on matching frequency range, supply voltage, package type, and power consumption specifications.
