FEP24C04YSOP8G/TR

FEP24C04 is a 4Kbit EEPROM device operating at temperatures up to 85℃. The device contains a 4K-bit (512×8) memory array organized in 16-byte pages. With a wide operating voltage range of 1.7V ~ 5.5V and operating frequency up to 1MHz, it is suitable for most applications. The product offers low-power operation and low standby current. The device is available in lead-free, RoHS-compliant, halogen-free or green packages. Available package types include 8-pin SOIC, TSSOP, and UDFN. FEP24C04 is compatible with the standard I²C bus protocol. This simple bus consists of a Serial Clock (SCL) and Serial Data (SDA) signal. Using this bus protocol, a master device (such as a microcontroller) can typically control one or more slave devices, such as this FEP24C04. The bit stream over the SDA line contains a series of bytes used to identify a specific slave device, instructions, an address within that slave device, and a series of data (if applicable). FEP24C04 also provides write protection via the WP pin to prevent overwriting data stored in the memory array. To prevent the state machine from entering an erroneous state during power-up sequences or power switching, a built-in power-on reset circuit is provided. During power-up, the device will not respond to any instructions until the supply voltage (VCC) reaches an acceptable stable level above the reset threshold voltage. Once VCC exceeds the power-on reset threshold, the device is reset and enters standby mode. This also prevents any unintended write operations from occurring during the power-up phase. During power-down, once VCC drops below the power-on reset threshold voltage, the device enters standby mode. In addition, after receiving a Stop command, the device will also be in standby mode as long as no internal write operation is in progress. However, sending commands is illegal unless VCC is within its operating voltage range. An optional additional 16-byte page (Identification Page) is available for this product. The Identification Page can be used to store sensitive application parameters that can (later) be permanently locked in read-only mode.
