BR24G128F-3AGTE2

Memory IC Overview

The BR24G128F-3AGTE2 is a 128-kbit (16K x 8) serial EEPROM manufactured by Rohm Semiconductor. It utilizes an I2C bus interface with a maximum clock frequency of 1 MHz. The device operates within a supply voltage range of 1.7 V to 5.5 V and is housed in an SOP-8 surface-mount package. It supports a wide operating temperature range from -40°C to +85°C and offers a data retention period of 40 years.

Memory IC Feature Summary

• Supports high-speed I2C communication up to 1 MHz
• Wide single-supply voltage operation from 1.7 V to 5.5 V
• Robust data retention capability for long-term storage

Memory IC Applications

• Consumer electronics requiring non-volatile configuration storage
• Industrial control systems needing reliable parameter logging
• Automotive modules utilizing standard I2C interfaces

Memory IC Procurement Notes

Verify the specific suffix '3A' against the official datasheet to confirm pinout and electrical characteristics, as ordering suffixes can indicate variations in packaging or specifications. Confirm availability status, as this component may be designated as Not Recommended for New Designs (NRND). Ensure compatibility with existing PCB footprints before procurement.

Memory IC Selection Notes

Select this component when a 128-kbit capacity is required with I2C connectivity. Consider the 1 MHz speed advantage over slower variants if system timing permits. Evaluate the SOP-8 package constraints against board space requirements. Verify that the 1.7 V minimum operating voltage aligns with the target system's power rail stability under all load conditions.

Memory IC Part Context

This part belongs to the BR24G series of serial EEPROMs from Rohm Semiconductor. These devices are designed for applications requiring frequent data updates with low power consumption. The series typically includes various densities and package options to accommodate different design constraints while maintaining standardized I2C protocol compatibility across the family.

Memory IC Replacement Considerations

BR24G128FVJ-3AGTE2: Same density and interface, but uses TSSOP-BJ-8 package instead of SOP-8. Verify footprint compatibility before substitution.
