RX4111CE A6

Real Time Clock Overview

The Epson RX4111CE is a real-time clock module designed for precise timekeeping in electronic systems. It integrates a high-precision quartz crystal oscillator with internal timing and power management circuits. The device supports a wide operating voltage range of 1.6V to 5.5V and features ultra-low power consumption, particularly in battery backup mode where current draw is in the microampere range. It includes built-in temperature compensation to maintain accuracy across varying thermal conditions and provides non-volatile memory for configuration storage.

Real Time Clock Procurement Notes

Verify component authenticity through authorized distributors. Confirm package type matches design requirements. Check date codes for freshness. Ensure supply chain stability for long-term production needs.

Real Time Clock Selection Notes

Select based on required timing accuracy and power constraints. Consider temperature range compatibility with target application environment. Evaluate board space availability for compact packaging options like QFN or SOP.

Real Time Clock Part Context

Part of Epson's broader portfolio of timing devices including crystals, oscillators, and sensors. Designed under Epson's 'save, small, precise' philosophy focusing on low power and miniaturization.

Real Time Clock Replacement Considerations

Direct substitutes require matching voltage range, pinout compatibility, and timing specifications. Verify interface protocols and memory capacity if using non-volatile features.
