RX-4803LC:UB3 PURE SN

Real Time Clock Overview

The RX-4803LC:UB3 PURE SN is a Real Time Clock (RTC) integrated circuit manufactured by Epson. It features an SPI interface and operates within a temperature range of -40°C to +85°C with a frequency tolerance of +/-5.0 PPM. The component is housed in a 12-TFSOJ package, measuring 2.40mm in width, and is supplied in Tape & Reel (TR) packaging.

Real Time Clock Feature Summary

• Integrated real-time clock and calendar functionality
• SPI serial interface for data communication
• Industrial temperature range operation capability

Real Time Clock Applications

• General purpose timekeeping systems
• Data logging devices requiring accurate timestamps
• Embedded systems needing calendar functions

Real Time Clock Procurement Notes

Verify the specific suffix 'PURE SN' against official Epson documentation to ensure correct material compliance and lead time specifications. Confirm that the 12-TFSOJ package dimensions match your PCB footprint requirements before finalizing procurement orders.

Real Time Clock Selection Notes

Select this component when an SPI interface is required for RTC functionality in industrial environments. Ensure the +/-5.0 PPM accuracy meets system timing constraints. Verify compatibility with the 12-TFSOJ surface mount package for assembly processes.

Real Time Clock Part Context

This part belongs to the Epson RX-4803LC series of real-time clocks. It shares the core RTC architecture with other variants in the family but differs in packaging, supply format, and specific ordering suffixes which may indicate material or handling characteristics.

Real Time Clock Replacement Considerations

Direct substitutes include other RX-4803LC variants such as RX-4803LC:UC3 PURE SN, provided the package and interface requirements are identical. Cross-referencing datasheets is essential to confirm pinout and electrical parameter compatibility.
