RX8900SA:UC3 PURE SN

Real Time Clock Overview

The RX8900SA:UC3 PURE SN is a Real-Time Clock (RTC) integrated circuit manufactured by EPSON. It provides clock/calendar functions via an I2C interface in a 14-SOP package. The device operates on a supply voltage of 2.5V to 5.5V, with battery backup support from 1.6V to 5.5V. Maximum current consumption during timing is 1.4µA to 1.5µA at 3V to 5V. It supports date formats YY-MM-DD-dd and time formats HH:MM:SS (24-hour). The component functions within a temperature range of -40°C to 85°C and includes alarm features.

Real Time Clock Feature Summary

• I2C bus interface for digital communication
• Integrated alarm function capability
• Surface mount 14-SOP (14-SOIC, 5.00mm width) packaging
• Wide operating voltage range: 2.5V to 5.5V

Real Time Clock Applications

• General purpose real-time clocking in embedded systems
