General Description

The AK93C45B/55B/65B/75B is a 1024/2048/4096/8192-bit serial CMOS EEPROM divided into 64/128/256/512 registers of 16 bits each. The AK93C45B/55B/65B/75B has 4 instructions such as READ, WRITE, EWEN and EWDS. Those instructions control the AK93C45B/55B/65B/75B. The AK93C45B/55B/65B/75B 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 write operation.
