RX8804CE XAB

Real Time Clock Overview

The RX8804CE XAB is a Real-Time Clock (RTC) IC manufactured by Epson Timing. It provides clock/calendar functions via an I2C bus interface. The device operates within a supply voltage range of 1.6 V to 5.5 V and consumes a maximum current of 1.5 µA to 1.6 µA at 3 V to 5 V. It supports date formats including YY-MM-DD-dd and time formats in HH:MM:SS (24-hour). The component is designed for surface mount installation in a 10-SMD, no-lead package with dimensions of 3.2 x 2.5 mm. It features an alarm function and operates across a temperature range of -40°C to +105°C.
