General Description

The AK93C45C/55C/65C is a 1024/2048/4096-bit serial CMOS EEPROM divided into 64/128/256

registers of 16 bits each. The AK93C45C/55C/65C has 6 instructions such as READ, WRITE,

PAGE WRITE, EWEN, EWDS and WRAL. Those instructions control the AK93C45C/55C/65C.

The AK93C45C/55C/65C can operate full function under wide operating voltage range. The

charge up circuit is integrated for high voltage generation that is used for write operation.
