RTC-8564JE:ROHS

Real Time Clock Overview

The EPSON RTC-8564JE:ROHS is a Real-Time Clock (RTC) IC designed for precise timekeeping in embedded systems. It features an I2C serial interface and supports date formats including YY-MM-DD-dd. The device operates within a supply voltage range of 1.8V to 5.5V and functions across a temperature range of -40°C to +85°C. Key specifications include a maximum current consumption of 0.65µA at 2V and 0.8µA at 5V. The component is housed in a 12-TFSOJ package with dimensions of 0.094 inches (2.40mm) width, designated as 12-VSOJ in supplier documentation.

Real Time Clock Procurement Notes

Verify the specific suffix JE:ROHS against manufacturer datasheets to confirm RoHS compliance status and exact pinout configuration. Check DigiKey part number SER3779TR-ND or similar distributors for availability, noting that the RX-8564LC series may be subject to End-of-Life (EOL) notices. Confirm package type matches the 12-TFSOJ specification required for PCB layout compatibility.

Real Time Clock Selection Notes

Select this component when a low-power, I2C-compatible RTC is needed for industrial environments. Ensure the system voltage falls within the 1.8V–5.5V range. Verify that the 12-TFSOJ package footprint is available on the target PCB. Consider the integrated alarm and leap year calculation features if software overhead needs to be minimized.

Real Time Clock Part Context

This part belongs to the Epson RX-8564LC series of real-time clocks. It is a CMOS-based device offering high precision and low power consumption. The series is designed for applications where space constraints and power efficiency are critical, such as portable electronics and industrial instrumentation. The JE:ROHS suffix indicates specific manufacturing and environmental compliance attributes.

Real Time Clock Replacement Considerations

The RX8130CE B6 is listed as a substitute by distributors. Verify electrical compatibility, specifically I2C address and register mapping, before replacement. Ensure the alternative package fits the existing footprint or allows for re-layout.
