DESCRIPTION
(cont’d) The memory is patible with the I2C extended addressing standard, two wire serial interface which uses a bi-directional data bus and serial clock. The memory carries a built-in 4 bit, unique device identification code (1010) corresponding to the I2C bus definition. The memory behaves as slave...
