AT24C02CDBVRG

The AT24C02C is a 2-Kbit I²C-compatible serial EEPROM. The device is designed to operate with a supply voltage range of 1.7V to 5.5V, a maximum transfer rate of 1MHz, and an operating temperature range of -40°C to +105°C. It integrates a write protection pin for hardware write protection of the entire memory array. In addition, it offers a software write protection feature that allows users to write-protect the entire memory array. The memory array is organized as 16 pages of 16 bytes each, for a total of 256×8 bits. The device also provides an additional 16-byte identification page for users to store sensitive application parameters. Once data is written to the identification page, it can be permanently locked in read-only mode. The device also features a separate memory block (read-only mode) containing a factory-programmed 128-bit unique ID, accessible by issuing a specific read command. The AT24C02C is available in lead-free, RoHS-compliant packages: DIP-8, SOP-8, MSOP-8, DFN-8, and SOT23-5.
