BR25G640FJ-3GE2

Memory IC Overview

The BR25G640FJ-3GE2 is a 64 kbit Serial EEPROM manufactured by ROHM Semiconductor, organized as 8 k x 8 bits. It utilizes an SPI bus interface with a maximum clock frequency of 20 MHz. The device operates within a supply voltage range of 1.6 V to 5.5 V and supports SMD/SMT installation in an SOP-J-8 package. It features a data retention period of 100 years and functions across a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed serial communication via SPI bus interface
• Operates on a wide single power supply voltage range
• Provides long-term non-volatile data retention

Memory IC Applications

• Data logging systems requiring persistent storage
• Configuration parameter storage in embedded controllers
• Calibration data retention for sensor modules

Memory IC Procurement Notes

Verify the specific suffix '3GE2' against official ROHM documentation to confirm pinout compatibility and tape-and-reel specifications. Confirm that the component meets RoHS requirements for your target market. Check current lifecycle status, as similar variants may be marked Not Recommended for New Designs. Ensure the SOP-J-8 footprint matches your PCB design guidelines before finalizing procurement orders.

Memory IC Selection Notes

Select this component when an SPI interface is required for higher throughput compared to I2C alternatives. The 20 MHz clock speed offers faster read/write cycles than standard 10 MHz EEPROMs. Verify that the 1.6 V minimum operating voltage aligns with your system's power rails. Consider the SOP-J-8 package dimensions for space-constrained designs.

Memory IC Part Context

This part belongs to the BR25G series of serial EEPROMs from ROHM Semiconductor. It provides non-volatile memory solutions for consumer electronics and industrial applications. The series is characterized by low power consumption and robust data retention capabilities suitable for frequent write operations.

Memory IC Replacement Considerations

BR25G640FJ-5A is listed as a recommended replacement with the same pinout and density.
