BR24T04FVM-WTR

Memory IC Overview

The BR24T04FVM-WTR is a 4-kbit (512 x 8) serial electrically erasable programmable read-only memory manufactured by ROHM Semiconductor. It operates via an I2C bus interface with a maximum clock frequency of 400 kHz. The device supports a supply voltage range from 1.6 V to 5.5 V and functions within an operating temperature range of -40°C to +85°C. It utilizes an 8-pin MSOP package for surface mount installation. Key electrical characteristics include a maximum active read current of 500 µA, a standby current of 2 µA, and a maximum power supply current of 2 mA. Data retention is specified at 40 years.

Memory IC Feature Summary

• Supports high-speed I2C communication with standard mode frequencies up to 400 kHz.
• Provides long-term data retention capability of 40 years without power.
• Operates across a wide voltage range starting from 1.6 V for low-power applications.

Memory IC Applications

• Data logging in portable electronic devices
• Configuration storage in consumer electronics
• Parameter saving in industrial control systems

Memory IC Procurement Notes

Verify component authenticity through authorized channels as the part status indicates end-of-life or not recommended for new designs. Confirm package integrity upon receipt, as the MSOP-8 form factor requires careful handling during inspection. Ensure compatibility with existing I2C bus protocols before integration into final assemblies.

Memory IC Selection Notes

Select this component when a 4-kbit capacity is required within the BR24T series family. Consider the MSOP-8 package dimensions for PCB layout constraints. Evaluate the 1.6 V minimum operating voltage against system power rails. Compare endurance and retention specifications against alternative EEPROM options if higher durability is needed.

Memory IC Part Context

This part belongs to the BR24T-W series of serial EEPROMs designed for general-purpose data storage. It shares pinout and functional similarities with other densities in the BR24T family, such as the 2-kbit and 64-kbit variants. The suffix WTR denotes specific packaging and taping configurations for automated assembly processes.

Memory IC Replacement Considerations

The BR24H64FVM-5AC is listed as a similar level replacement with the same pinout and package, though it offers different density and performance characteristics. Verify electrical parameter alignment before substitution.
