RTC-8564JE:B0 ROHS

Real Time Clock Overview

The EPSON RTC-8564JE:B0 ROHS is a Real-Time Clock (RTC) IC belonging to the RX-8564LC series, manufactured by Epson. It integrates a clock/calendar function with an I2C bus interface for data communication. The device operates within a supply voltage range of 1.8V to 5.5V and supports a 24-hour time format. It features a 12-VSOJ package with dimensions of 7.3mm x 6.2mm x 1.5mm. Key electrical characteristics include a maximum current consumption of 0.65µA at 2V and 0.8µA at 5V. The component is designed for surface mount installation and functions reliably across a temperature range of -40°C to +85°C.

Real Time Clock Feature Summary

• Integrated Real-Time Clock and Calendar functionality with I2C serial interface
• Low power consumption: 0.65µA @ 2V and 0.8µA @ 5V
• Wide operating voltage range from 1.8V to 5.5V
• Compact 12-VSOJ surface mount package (7.3 x 6.2 x 1.5 mm)

Real Time Clock Applications

• Portable electronic devices requiring precise timekeeping
• Industrial equipment needing stable clock sources in varying temperatures
• Consumer electronics utilizing low-power real-time tracking

Real Time Clock Procurement Notes

Verify the specific suffix 'B0' against official Epson documentation to confirm exact manufacturing lot or revision details, as suffixes often denote specific packaging or material compliance variations. Confirm availability status, as related models in this series may have end-of-life notifications. Ensure the RoHS compliance matches current regulatory requirements for the target market.

Real Time Clock Selection Notes

Select this component when an I2C interface is required for system integration. The 1.8V to 5.5V supply range allows compatibility with various logic levels without additional level shifting in many cases. Consider the 12-VSOJ package size constraints during PCB layout. Verify that the -40°C to +85°C industrial temperature range meets the environmental conditions of the final application.

Real Time Clock Part Context

This part belongs to the RX-8564LC series of Real-Time Clocks from Epson. These modules combine a 32.768kHz quartz crystal oscillator with the RTC circuitry, eliminating the need for external frequency adjustment. The JE package variant offers a specific footprint distinct from other series members like LC or NB, facilitating design-in for applications with specific board space requirements.

Real Time Clock Replacement Considerations
