HX24LC04BDBVRG

HX24LC04B is a 4K-bit 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 protection pin for hardware write protection of the entire memory array. In addition, the device provides a software write protection feature, allowing users to write-protect the entire memory array. The memory array consists of 32 pages of 16 bytes each, for a total of 512×8 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 to read-only mode. The device also provides a separate memory block (read-only mode) containing a factory-programmed 128-bit unique ID, accessible by issuing a specific read command. HX24LC04B is available in lead-free green packages: DFN-8, MSOP-8, SOP-8, DIP-8, and SOT23-5.
