    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)
  • Page 25 to an internal state-machine which controls the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the device is similar to reading from 5.0 V and 12.0 V Flash or EPROM devices. The MBM29LV160TE/BE is programmed by executing the program command sequence.
