BR24T08FJ-WE2

Product Overview

The Rohm Semiconductor BR24T08FJ-WE2 is a surface-mount non-volatile EEPROM memory IC offering 8Kbit of storage in an 8-SOP-J package. Its 1K x 8 organization and I2C serial interface support clock frequencies up to 400 kHz, allowing microcontrollers and host processors to read and write configuration or calibration data over a compact two-wire bus. The device operates from a 1.6V to 5.5V supply and is rated for an ambient temperature range of -40°C to 85°C. Write cycle time for word or page operations is 5ms, making it suitable for embedded systems that need persistent data retention with a small footprint.

Design & Procurement Notes

For schematic and layout planning, the BR24T08FJ-WE2 requires an I2C connection and a surface-mount 8-SOP-J footprint, so bus pull-up requirements and package land pattern should be considered during PCB design. The 1.6V to 5.5V supply range should be checked against the system rail and logic interface, while the 400 kHz clock rate and 5ms write cycle time should be reflected in firmware timing and write-management routines. Designers should also confirm that the -40°C to 85°C ambient operating range matches the product environment and that the 8Kbit 1K x 8 organization provides sufficient persistent data capacity.
