ECS-RTC-3225-5609-TR

Real Time Clock Overview

The ECS-RTC-3225-5609-TR is a Real Time Clock 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 ranging from 1.6V to 5.0V when VDD equals VBAT, or up to 5.0V in normal mode. Battery supply current consumption is typically 3.0 µA. Frequency stability is ±5 ppm between -20°C and +70°C, with aging specified at ±3 ppm.

Real Time Clock Procurement Notes

Verify the specific ordering suffix '-TR' indicates tape and reel packaging configuration as per manufacturer standards. Confirm RoHS compliance status and ensure the selected variant matches the required voltage and temperature specifications for the target application environment before finalizing procurement orders.

Real Time Clock Selection Notes

Select this component when a compact RTC solution with integrated TCXO is required to minimize external crystal components. Ensure the system design accommodates the 1.6V to 5.0V supply range and utilizes an I²C master compatible with the module's protocol. Consider the ±5 ppm stability requirement against environmental temperature variations during operation.
