    2-1-3 Serial EEPROM, 2K (256 x 8) (24C02) or 16 K (2048 x 8) (24C16) 24C02 is used for DVD player while 24C16 is for DVD receiver. The capacity is the only difference between two kinds of serial EEPROM. Both of them use same package and have same pin configuration. * Features Low-Voltage and Standard-Voltage Operation -5.0 (V CC = 4.5V to 5.5V)
