General Description
The AK6004A/08A is a 4096/16384-bit serial CMOS EEPROM divided into 512/2048 registers of 8 bits each. The AK6004A/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 AK6004A/08A 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 u……
