Introduction

AI Translation

The AT24C256C is a 256-Kbit I²C-compatible Serial EEPROM (Electrically Erasable Programmable Memory) 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. The operating temperature range is from -40℃ to +105℃. The device incorporates a Write Protection pin used for hardware Write Protection on the whole memory array. The Serial EEPROM memory is organized as 512 pages of 64 bytes each, totaling 32768*8 bits. The device offers an additional 64-byte Identification Page for users to store sensitive application parameters. This page can be permanently locked in Read-only mode after the application data is written into the Identification Page. The AT24C256C also offers a separate memory block containing a factory programmed 128-bit Unique ID. This block is in Read-only mode and can be accessed to by sending a specific Read command. The AT24C256C is delivered in Lead-free green packages: DIP-8, TSSOP-8, SOP-8, MSOP-8.
