ECS-RTC-3225-5699HS-TR

Real Time Clock Overview

The ECS-RTC-3225-5699HS is a low-power Real-Time Clock (RTC) module featuring an integrated I²C bus interface and a built-in 32.768 kHz Temperature Compensated Crystal Oscillator (TCXO). It supports calendar functions including year, month, day, hour, minute, and second tracking, alongside clock and timer capabilities. The device operates with a power supply voltage of 1.6V to 5.0V when VDD equals VBAT, or 2.5V to 5.0V in normal mode. Key electrical characteristics include a battery supply current consumption of 0.5 µA, frequency stability of ±5 ppm over the -40°C to +85°C operating temperature range, and an aging rate of ±3 ppm per year.
