The FT24C256A-ETR-B is an EEPROM (Electrically Erasable Programmable Read-Only Memory) IC from Fremont Micro Devices. It is a 256-Kbit (32K × 8) serial EEPROM and has been designed for use in applications such as personal computers, consumer, automotive electronics, and industrial equipment. The IC has a TSSOP-8 package, meaning it has 8 pins and is surface-mounted. The package is RoHS compliant, meaning it is compliant with the Restriction of Hazardous Substances Directive from the EU which limits the usage of certain hazardous substances in electrical and electronic equipment. The FT24C256A-ETR-B has an operating voltage range between 2.5V and 5.5V and has a maximum frequency of 1MHz. The device is designed to minimize power consumption with active lows speed and standby low current. It has low- voltage and program/erase cycle functionalities and write-protect features. Data is stored over a wide temperature range of -40°C to +85°C.
