[AK6010A/12A]
General Description
The AK6010A/12A is a 32768/65536-bit serial CMOS EEPROM divided into 4096/8192 registers of
8 bits each.
The AK6010A/12A 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 AK6010A/12A conforms to all specifications in the 2 wire protocol and is controlled by serial
clock (SCL) 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.
