RX-4575LC:B3:PURE SN

Real Time Clock Overview

The RX-4575LC:B3:PURE SN is a Real Time Clock module manufactured by Epson Timing. It integrates a built-in frequency-adjusted 32.768 kHz crystal unit and utilizes a 3-wire serial interface (SPI). The device operates within a power voltage range of 1.6 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. Key features include external event detection with selectable Hi/Lo detection, a built-in 12-bit counter for timer functions, and alarm capabilities based on day, hour, and minute combinations. The module provides low backup current consumption, typically 0.35 µA at 3 V.

Real Time Clock Feature Summary

• Built-in 32.768 kHz crystal unit requiring no frequency adjustment
• External event detection with chattering filter options (8 ms, 31 ms, 62 ms, 125 ms)
• 3-wire serial interface (SPI) with selectable pull-up or pull-down resistors
• Low backup current consumption of 0.35 µA typical at 3 V

Real Time Clock Applications

• Car Multimedia systems
• Body Electronics
• Remote Keyless Entry systems

Real Time Clock Procurement Notes

Verify the specific ordering suffix B3 against official documentation to confirm package type and environmental compliance details. Ensure compatibility with the 3-wire SPI interface requirements. Check for RoHS and REACH compliance status as indicated in the product specifications.

Real Time Clock Selection Notes

Select this model when a compact RTC with integrated crystal and external event detection is required. The 3-wire interface suits applications needing faster data rates than I2C. Consider the VSOJ-12 package dimensions (3.6 mm x 2.8 mm x 1.2 mm max) for PCB layout constraints.
