RTC-4574JE:B3 ROHS

Real Time Clock Overview

The RTC-4574JE:B3 ROHS is a Real-Time Clock (RTC) integrated circuit manufactured by Epson Timing. It features a 3-wire serial interface and supports date formats of YY-MM-DD-dd and time formats of HH:MM:SS in 24-hour mode. The device operates within a supply voltage range of 1.6V to 5.5V, with a maximum timing current of 1µA to 2µA at 3V to 5V. It includes alarm and leap year correction features. The component is housed in a 14-SOIC package (0.197", 5.00mm width) and is designed for surface mount installation. It functions reliably across an operating temperature range of -40°C to +85°C.

Real Time Clock Procurement Notes

Verify the specific suffix JE against the manufacturer's part number guide to confirm pinout and electrical characteristics, as variations exist within the RTC-4574 series. Confirm RoHS compliance status directly from the latest datasheet or supplier documentation before procurement.

Real Time Clock Selection Notes

Select this component when a low-pin-count serial interface is required for timekeeping in space-constrained designs. Ensure the system voltage falls within the 1.6V to 5.5V range. Consider the 14-SOIC package dimensions for PCB layout compatibility.

Real Time Clock Part Context

This part belongs to the Epson RTC-4574SA/SA/B3 series family. It shares core functionalities with other variants like the RTC-4574SA:B3 but may differ in specific packaging or minor electrical parameters defined by the JE suffix.
