RV-8564-C2-32.768KHZ-10PPM-TA-QC

Real Time Clock Overview

The RV-8564-C2 is a hermetically sealed SMT Real-Time Clock module integrating a CMOS circuit and a 32.768 kHz tuning fork crystal within a 5.0 x 3.2 x 1.2 mm ceramic package. It operates on a supply voltage of 1.0 V to 5.5 V for timekeeping and 1.8 V to 5.5 V during I2C bus activity, with typical current consumption of 250 nA at 3 V. The device provides year, month, date, weekday, hours, minutes, and seconds via an I2C interface supporting 400 kHz speeds. It features programmable clock outputs, alarm functions, and low voltage detection.

Real Time Clock Procurement Notes

Verify the specific ordering suffixes against the manufacturer's documentation to confirm temperature range and qualification grade. The 'TA' suffix indicates a standard operating temperature range of -40 to +85°C, while 'QC' denotes commercial grade. Confirm that the package termination processing meets IPC/JEDEC J-STD-020C standards for 260°C reflow soldering.

Real Time Clock Selection Notes

Select this component when a hermetically sealed RTC module is required for vacuum operation environments. Ensure the application supports the 1.2 V to 5.5 V operating voltage range and requires the specific 5.0 x 3.2 x 1.2 mm footprint. Verify compatibility with the I2C protocol and check if the available clock output frequencies meet system synchronization needs.
