| Description & Applications | The AK93C45A/55A/65A/75A is a 1024/2048/4096/8192-bit serial CMOS EEPROM divided into 64/128/256/512 registers of 16 bits each. The AK93C45A/55A/65A/75A has 4 instructions such as READ, WRITE, EWEN and EWDS. Those instructions control the AK93C45A/55A/65A/75A. The AK93C45A/55A/65A/75A can operate full function under wide operating voltage range from 1.8V to 5.5V. The charge up circuit is integrated for high voltage generation that is used for writeoperation. A serial interface of AK93C45A/55A/65A/75A, consisting of chip select (CS), serial clock (SK), datain (DI) and data-out (DO), can easily be controlled by popular microcontrollers or standard microprocessors. AK93C45A/55A/65A/75A takes in the write data from data input pin (DI) to a register synchronously with rising edge of input pulse of serial clock pin (SK). And at read operation, AK93C45A/55A/65A/75A takes out the read data from a register to data output pin (DO) synchronously with rising edge of SK. The DO pin is usually in high impedance state. The DO pin outputs "L" or "H" in case of data output or Busy/Ready signal output.
