HX24LC02BDRG

HX24LC02B is a 2 Kbit I²C-compatible serial EEPROM. The device is designed to operate over a supply voltage range of 1.7V to 5.5V, with a maximum transfer rate of 1MHz and an operating temperature range of -40°C to +105°C. The device integrates a write-protect pin for hardware write protection of the entire memory array. It also provides a software write protection feature for write-protecting the entire memory array. The memory array is organized as 16 pages of 16 bytes each, totaling 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 additionally provides a separate memory block (read-only mode) containing a factory-programmed 128-bit unique ID, accessible by issuing a specific read command. The HX24LC02B is available in lead-free green packages: DIP-8, SOP-8, MSOP-8, DFN-8, and SOT23-5.
