AT24C02CN

The AT24C02C is a 2-Kbit I²C-compatible serial EEPROM device. The device is designed to operate in a supply voltage range of 1.7V to 5.5V, with a maximum of 1MHz transfer rate, over an operating temperature range of -40℃ to +105℃. The device incorporates a Write Protection pin used for hardware Write Protection on the whole memory array. The device also offers a Software Write Protection feature for users to write protect the whole memory array. The memory array is organized as 16 pages of 16 bytes each, totaling 256*8 bits. The device offers an additional 16-byte Identification Page for users to store sensitive application parameters. This page can be permanently locked in Read-only mode after the data is written into the Identification Page. The device also offers a separate memory block (in Read-only mode) containing a factory programmed 128-bit Unique ID and can be accessed to by sending a specific Read command. I²C is delivered in lead-free green packages: DIP-8, SOP-8, MSOP-8, DFN-8 and SOT23-5.
