Microelectronics.The FM24C04D-SO-T-G is a 4-Kbit Electrically Erasable Programmable Read-only Memory (EEPROM) in a SOP-8 surface-mount package from Fudan Microelectronics. This device is RoHS compliant, and can be used for applications such as code and data storage, and for a control and address purposes. It is non-volatile, performing read and write operations without the need for external power. It also offers a low-power AT24C04C version and a 1.8V to 5.5V operating voltage range. The device can operate over a temperature range of -40°C to +85°C. It has an inherent write protection that prevents interference between an active program and a peripheral device. The FM24C04D-SO-T-G offers an I2C bus, two system reset pins, and an address latch enable pin that can be used for communication, as well as a four-byte page write buffer and 32-byte random read buffer. Applications include code and data storage, system control and address coding for a wide variety of applications.
