BR24T128FVM-WTR

Memory IC Overview

The BR24T128FVM-WTR is a serial electrically erasable programmable read-only memory (EEPROM) manufactured by Rohm Semiconductor. It features a storage capacity of 128 kbit organized as 16k x 8 bits and utilizes an I2C bus interface with a maximum clock frequency of 400 kHz. The device operates within a supply voltage range of 1.6 V to 5.5 V and is housed in an 8-MSOP package. It supports surface mount installation and functions across a temperature range of -40°C to +85°C, offering a data retention period of 40 years.

Memory IC Feature Summary

• Supports high-speed I2C communication up to 400 kHz
• Provides long-term non-volatile data retention
• Operates with wide voltage compatibility

Memory IC Applications

• Data logging systems requiring persistent storage
• Configuration parameter storage in embedded devices
• Calibration data preservation in industrial sensors

Memory IC Procurement Notes

Verify the component status before procurement as this part may be classified as Not Recommended for New Designs (NRND). Confirm that the 8-MSOP package and specific suffix align with existing board layouts. Ensure compliance with RoHS standards and check for any obsolescence notices from the manufacturer prior to finalizing supply chain agreements.

Memory IC Selection Notes

Select this component when a 128 kbit EEPROM with I2C interface is required in an 8-MSOP package. It is suitable for applications needing operation between 1.6 V and 5.5 V. Consider the NRND status for new projects and evaluate alternative future-proof parts if long-term availability is critical. Verify thermal performance within the specified -40°C to +85°C operating range.

Memory IC Part Context

This part belongs to the BR24T series of serial EEPROMs from Rohm Semiconductor. It shares architectural similarities with other members like the BR24T04FVM-WTR and BR24T64FVM-WTR but offers higher density. The 'WTR' suffix indicates tape-and-reel packaging for automated assembly. It is distinct from the SOP-8 packaged BR24T128F-WE2 variant.
