RTC-8564JE0:ROHS

Real Time Clock Overview

The Epson RTC-8564JE0:ROHS is a Real-Time Clock (RTC) integrated circuit designed for precise timekeeping in electronic systems. It features an I2C-bus interface for communication with host microcontrollers. The device integrates a crystal oscillator, eliminating the need for external frequency adjustment components. Key electrical specifications include a minimum operating voltage of 1.6 V and a maximum of 5.5 V. It supports standard date formats (YY-MM-DD) and time formats (HH:MM:SS). The component operates within a temperature range of -40°C to +85°C and is housed in a JE package (7.3 x 6.2 mm), suitable for surface-mount applications.

Real Time Clock Procurement Notes

Verify the specific ordering suffix '0:ROHS' against official Epson documentation to confirm compliance with Restriction of Hazardous Substances directives. Ensure the JE package dimensions match the target PCB footprint. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Real Time Clock Selection Notes

Select this model when an I2C interface is required for RTC functionality. The wide voltage range (1.6V–5.5V) allows compatibility with various logic levels. Consider the JE package size for space-constrained designs. Verify that the integrated crystal meets the frequency stability requirements of the application without additional calibration.

Real Time Clock Part Context

This component belongs to Epson's RTC-8564 series, which are widely used real-time clock chips. The JE variant specifically denotes the package type and pin configuration. It is part of Epson's broader portfolio of timing solutions, including other interfaces like SPI and parallel buses, tailored for different integration needs.

Real Time Clock Replacement Considerations

Direct replacements must maintain I2C compatibility and similar voltage/temperature specs. Check Epson's official substitution guides for equivalent parts within the RTC-8564 family or alternative packages like LC or NB if form factor changes are permissible.
