RX8901CE XS A00

Real Time Clock Overview

The RX8901CE XS A00 is a real-time clock (RTC) module manufactured by Epson Timing. It features an I2C bus interface and operates within a supply voltage range of 1.6 V to 5.5 V. The device maintains time in HH:MM:SS (24-hour) format and date in YY-MM-DD-dd format. It offers a frequency tolerance of +/-3 ppm between -40°C and +85°C, expanding to +/-5 ppm between 85°C and +105°C. The component utilizes a 10-SMD, no-lead package with dimensions of 3.2 x 2.5 mm. It includes a FOUT pin output and is supplied in a reel packaging configuration.
