BR24G64-3

Memory IC Overview

The BR24G64-3 is a 64Kbit serial EEPROM utilizing an I²C bus interface. It features an 8K x 8 bit format and operates on a single power source ranging from 1.6V to 5.5V, supporting FAST MODE operation at up to 400kHz. The device includes a write protect (WP) function, page write capability for up to 32 bytes, and built-in noise filters on the SCL and SDA terminals. It guarantees 1 million write cycles and 40 years of data retention.

Memory IC Feature Summary

• Complies with world standard I²C BUS protocol using only serial clock and serial data ports.
• Supports wide operating voltage range suitable for battery applications.
• Includes write protect function and prevention of write mistakes at low voltage.
• Features built-in noise filters on input terminals.

Memory IC Applications

• Battery-powered devices requiring non-volatile storage
• Microcontroller systems needing shared port connectivity
• Industrial control units requiring write protection

Memory IC Procurement Notes

Verify the specific package variant required, as the BR24G64-3 family supports multiple packages including SOP8, TSSOP-B8, and VSON008X2030. Confirm that the selected part number matches the desired physical footprint and pin configuration. Ensure compatibility with the system's I²C pull-up resistor requirements and voltage levels before finalizing procurement.

Memory IC Selection Notes

Select this component when a 64Kbit capacity with I²C interface is needed. It is suitable for designs requiring operation down to 1.6V. Consider the WP terminal for hardware write protection. Verify that the chosen package fits the PCB layout constraints, as dimensions vary significantly between SOP, TSSOP, and VSON options.

Memory IC Part Context

This component belongs to the BR24G series of serial EEPROMs manufactured by ROHM Semiconductor. It is designed for general-purpose data storage in embedded systems. The -3 suffix typically denotes specific electrical characteristics or package variants within the broader product line.

Memory IC Replacement Considerations

Check for direct pin-compatible replacements within the same series. Ensure any substitute maintains the 1.6V to 5.5V operating range and 400kHz I²C speed. Verify that the replacement also offers the 8K x 8 bit organization and similar endurance ratings.
