二、  DESCRIPTION

   The AT24C02N-XXX  is  2048  bits  of  serial  Electrical  Erasable  and  Programmable  Read  Only Memory, commonly known as EEPROM. They are organized as 256 words of 8 bits (1 byte) each.  The devices are fabricated with proprietary advanced CMOS process for low power and low voltage applications. These devices are available in standard 8-lead DIP, 8-lead SOP, 8-lead MSOP, 8-lead TSSOP, 8-lead DFN and 5-lead SOT-23/TSOT-23 packages. A standard 2-wire serial interface is used to address all read and write functions.  Our extended V_CC range (1.8V to 5.5V) devices enables wide spectrum of applications.
