General Description
The AK6003A is a 2048-bit serial CMOS E
2
PROM divided into 256 registers of 8 bits each.
The AK6003A 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 AK6003A 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.
TERM
DESCRIPTION
Transmitter The device which sends the data to the bus
Receiver
The device which receives the data from the bus
Master
The device which initiates a transfer, generates clock signals and terminates
a transfer
Slave
The device addressed by a master

Write protection
Hardware Write Protection
If WC pin is High level, WRITE operations onto the entire array will not be executed. If the WC pin is
Low level, the AK6003A will be enabled to perform WRITE operation.
As the WC pin is internally pulled down to GND, the AK6003A will be enabled to perform WRITE
operation if the WC pin is left floating.
Software Write Protection
The software write protect register is programmed by sending a software write protect command
and the software write protection is enabled.
If the software write protection is enabled, Write operations onto the lower half of the array($00 $7F)
will not be executed permanently. Once the software write protect register has been programmed,
the write protection can not be reversed. The software write protection can not be reversed even if
the AK6003A is powered down.
If the WC pin is high level, WRITE operations onto the entire array will not be executed regardless of
the status of the software protection.
