RX6110SA:B3 PURE SN

Real Time Clock Overview

The RX6110SA:B3 PURE SN is a Real-Time Clock (RTC) integrated circuit manufactured by EPSON. It provides clock/calendar functions with I2C and SPI interfaces, supporting both 2-wire and 3-wire serial communication protocols. The device operates within a supply voltage range of 1.6V to 5.5V and includes 16 bytes of RAM for data storage. Key features include alarm capabilities, leap year compensation, and support for YY-MM-DD-dd date formats and HH:MM:SS time formats. It is housed in a 14-SOP package and functions reliably across an operating temperature range of -40°C to +85°C.

Real Time Clock Feature Summary

• Dual interface support for I2C and SPI communications
• Integrated 16-byte RAM for user data storage
• Low power consumption with standby current of 0.25µA to 0.27µA at 3V-5V
• Hardware leap year correction and alarm functionality

Real Time Clock Applications

• Industrial control systems requiring precise timekeeping
• Consumer electronics with battery backup requirements
• Automotive infotainment and instrument clusters
• IoT devices needing low-power real-time tracking

Real Time Clock Procurement Notes

Verify the specific ordering suffix against the manufacturer's part number system documentation to ensure correct packaging and material specifications. Confirm RoHS compliance status and REACH registration details prior to procurement. Check for moisture sensitivity level (MSL 1) handling requirements during storage and assembly processes.

Real Time Clock Selection Notes

Select this component when both I2C and SPI bus compatibility is required for system flexibility. Ensure the design supports the 1.6V minimum supply voltage if operating in low-power modes. Verify that the 14-SOP package dimensions fit the PCB layout constraints. Consider the 16-byte RAM capacity for application-specific data logging needs.

Real Time Clock Part Context

This part belongs to the RX6110SA series of real-time clocks from EPSON Timing. It shares functional similarities with other models in the family but is distinguished by its specific interface configuration and packaging. The series is designed for applications demanding high accuracy and low power consumption in compact form factors.

Real Time Clock Replacement Considerations

Direct substitutes may include other EPSON RTCs with compatible pinouts and electrical characteristics, such as the RX-8571SA series, provided interface and memory requirements align. Cross-reference datasheets for voltage ranges and package dimensions before substitution.
