RV-3032-C7-32.768KHZ-2.5PPM-TA-QC

Real Time Clock Overview

The RV-3032-C7 is a hermetically sealed SMD Real-Time Clock Module integrating a CMOS circuit and a 32.768 kHz tuning fork crystal within a miniature ceramic package. It operates on a supply voltage of 1.3 V to 5.5 V with a typical timekeeping current consumption of 160 nA at 3 V. The device provides high time accuracy of ±2.5 ppm across the -40°C to +85°C range, extending to ±20.0 ppm up to +105°C. Key electrical features include an I2C interface supporting 400 kHz, automatic backup switchover, and a user-programmable password for write protection.

Real Time Clock Procurement Notes

Verify the specific ordering suffix against the datasheet to confirm the intended qualification grade. The suffix 'QC' denotes Commercial Grade, while 'QA' indicates Automotive Grade AEC-Q200 qualification. Ensure the selected variant matches the required environmental and reliability standards for the target application before procurement.

Real Time Clock Selection Notes

Select this module when a hermetically sealed RTC with integrated XTAL is required for space-constrained designs. The C7 package size measures 3.2 x 1.5 x 0.8 mm. Consider the extended temperature performance limitations above +85°C if operating in high-heat environments. Verify that the I2C bus speed and voltage levels align with the host system requirements.

Real Time Clock Part Context

This component belongs to the RV-3032-C7 series of Real-Time Clock Modules manufactured by Micro Crystal AG. These modules combine a tuning fork crystal resonator with oscillator and RTC ICs in a single SMD ceramic package. The series supports various qualification grades and temperature ranges defined by the ordering suffixes.

Real Time Clock Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. When replacing this component, ensure the new part matches the 8-WCDFN (SON-8) footprint dimensions and pin configuration. Verify compatibility with the I2C protocol and voltage supply range of 1.3 V to 5.5 V.
