RV-4162-C7-32.768KHZ-20PPM-TA-QA

Real Time Clock Overview

The RV-4162-C7-32.768KHZ-20PPM-TA-QA is a hermetically sealed SMT Real-Time Clock module from Micro Crystal AG, housed in a 3.2 x 1.5 x 0.8 mm SON-8 ceramic package with a metal lid. It integrates a CMOS circuit and a 32.768 kHz crystal. The device operates on a supply voltage of 1.0 V to 4.4 V for timekeeping and 1.3 V to 4.4 V during I2C bus activity. Typical current consumption is 350 nA at 3 V. It provides time accuracy of ±20 ppm at 25°C with a maximum aging rate of ±3 ppm in the first year.

Real Time Clock Procurement Notes

Verify that the specific suffix 'QA' confirms Automotive Grade AEC-Q200 qualification as defined by the manufacturer's ordering information. Ensure the component meets IPC/JEDEC J-STD-020C soldering standards for 260°C peak reflow temperatures. Confirm RoHS compliance and Pb-free termination status before integration into production lines.

Real Time Clock Selection Notes

Select this module when high reliability and small form factor are required. The ±20 ppm accuracy at 25°C suits applications needing precise time without external calibration. The wide operating temperature range of -40 to +85°C supports harsh environments. Consider the 1.0 V minimum operating voltage for battery-powered designs requiring extended life.

Real Time Clock Part Context

This part belongs to the RV-4162-C7 series of Real-Time Clock Modules. The 'TA' suffix indicates the standard temperature range of -40 to +85°C. The 'QC' or 'QA' suffixes denote Commercial or Automotive grade qualifications respectively. The C7 designation refers to the specific 3.2 x 1.5 x 0.8 mm package size.

Real Time Clock Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Direct replacement requires matching the SON-8 footprint, I2C interface, and voltage specifications.
