RX-8571LC:B PURE SN

Real Time Clock Overview

The Epson RX-8571LC:B PURE SN is a Real Time Clock (RTC) integrated circuit belonging to the RX-4571LC series. It features a Serial 3-Wire bus interface and operates within a supply voltage range of 1.6 V to 5.5 V. The device supports a date format of YY-MM-DD-dd and a time format of HH:MM:SS in 24-hour mode. Designed for surface mount applications, it utilizes a VSOJ-12 package. The component functions reliably across an operating temperature range from -40°C to +85°C.

Real Time Clock Feature Summary

• Serial 3-Wire bus interface for data communication
• Operating voltage range of 1.6 V to 5.5 V
• VSOJ-12 surface mount package
• Temperature range of -40°C to +85°C

Real Time Clock Applications

• Industrial control systems requiring precise timekeeping
• Consumer electronics with limited power budgets
• Data logging equipment needing calendar tracking

Real Time Clock Procurement Notes

Verify the specific suffix 'B' against official Epson documentation to confirm pinout and electrical characteristics. Confirm availability status as current listings indicate no stock. Ensure the Serial 3-Wire interface compatibility matches the target system design requirements before procurement.

Real Time Clock Selection Notes

Select this component when a Serial 3-Wire interface is required instead of I2C. The VSOJ-12 package suits space-constrained PCB layouts. Verify that the 1.6 V minimum supply voltage aligns with the system's power rails. Consider the -40°C lower limit if operating in cold environments.

Real Time Clock Part Context

This part belongs to the RX-4571LC series, distinct from the RX-8571 family which typically uses I2C interfaces. The RX-4571LC series is characterized by its Serial 3-Wire connectivity and VSOJ packaging options. It serves as a specialized RTC solution for applications where standard I2C buses are not utilized or preferred.
