RX-8025SA:AA

Real Time Clock Overview

The RX-8025SA:AA is a Real-Time Clock (RTC) integrated circuit manufactured by Epson Timing. It features an I2C bus interface and provides clock/calendar functionality with alarm capabilities. The device operates within a supply voltage range of 1.7 V to 5.5 V, consuming a maximum current of 1.2 µA at 3 V and 1.8 µA at 5 V. It supports date formats including YY-MM-DD-dd and time formats in HH:MM:SS (24-hour). The component is housed in a 14-SOP package with a width of 5.00 mm and functions reliably across an operating temperature range of -40°C to +85°C.
