RTC-72423A3:PURE SN

Real Time Clock Overview

The RTC-72423A3:PURE SN is a Real Time Clock (RTC) IC manufactured by Epson Timing, belonging to the RTC-72423 series. It features a parallel interface and supports HH:MM:SS time formats in both 12-hour and 24-hour modes. The device operates within a supply voltage range of 4.5V to 5.5V and draws a maximum current of 5µA to 10µA at voltages between 2V and 5V. It includes leap year compensation and functions across an industrial temperature range of -40°C to +85°C. The component is housed in a surface-mount package.

Real Time Clock Feature Summary

• Parallel bus interface for clock/calendar data transfer
• Integrated leap year compensation feature
• Low power consumption with 5µA to 10µA current draw
• Industrial operating temperature range from -40°C to +85°C

Real Time Clock Applications
