FT24C04A-ELR-T EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The FT24C04A-ELR-T is a 4Kbit I2C EEPROM memory integrated circuit manufactured by Fremont Micro Devices Ltd. This non-volatile memory device operates at 1 MHz with a 550 ns access time and supports a supply voltage range of 1.8V to 5.5V. The device is packaged in SOT-23-5 (SC-74A) surface mount configuration and is compliant with RoHS3 and REACH standards.

The FT24C04A-ELR-T has been discontinued at DiGi Electronics. Equivalent substitute parts are available from the same manufacturer with identical electrical and mechanical specifications but different packaging or product status classifications.
