General Description
The AK6002A/04A/08A is a 2048/4096/16384-bit serial CMOS EEPROM divided into 256/512/2048 registers
of 8 bits each.
The AK6002A/04A/08A 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.
The AK6002A/04A/08A conforms to all specifications in the 2 wire protocol and is controlled by serial clock
(SK) and serial data (SDA) line.
Some devices can be connected to the same bus. Each device connected to the bus is software addressable
by a unique address, and can operate as either a transmitter or receiver. In addition to transmitters and
receivers, devices can also be considered as masters or slaves when performing data transfers (see Table1).
The master is the device which initiates a data transfers on the bus and generates the clock signals to permit
that transfer. At that time, the device addressed is considered as the slave.
