RV-3028-C7 TA QC
Overview
The RV-3028-C7 is an ultra-low power CMOS real-time clock module with an integrated 32.768 kHz quartz crystal and factory-calibrated accuracy of +/-1 ppm. It operates at an exceptionally low current of 45nA at 3V, making it ideal for always-on timing in battery-constrained applications. The device includes a unique 43-byte EEPROM for non-volatile configuration and a password-protected write system for enhanced security.
Why Choose This Part
The RV-3028-C7 stands out for its extreme 1ppm accuracy and industry-leading low current draw of 45nA. It simplifies hardware design by integrating the crystal and a trickle charger for backup capacitors or batteries into a tiny 3.2 x 1.5 mm package.
Applications
Getting Started
Communicate with the device over a standard I2C bus using a supply voltage between 1.1V and 5.5V. Developers should utilize the integrated backup switchover circuit to automatically transition between VDD and a backup power source such as a supercapacitor or button cell.
