ChipNobo AT24C04C-SSHM-T-CN

AT24C04C-SSHM-T-CN is a 4Kbit I²C-compatible serial EEPROM device. The device is designed to operate over a voltage range of 1.7V to 5.5V, with a maximum transfer rate of 1MHz and an operating temperature range of -40℃ to +105℃. The device integrates a write protection pin for hardware write protection of the entire memory array. It also provides a software write protection feature, allowing users to write-protect the entire memory array. The memory array is organized as 32 pages of 16 bytes each, totaling 512×8 bits. The device offers an additional 16-byte identification page for users to store sensitive application parameters. This page can be permanently locked to read-only mode after data has been written to it. The device also provides a separate memory block (in read-only mode) containing a factory-programmed 128-bit ID, accessible by issuing a specific read command. AT24C04C-SSHM-T-CN is available in a lead-free green package: SOP.
