The Atmel 1 Kbit three-wire serial EEPROM with user-selectable memory organization at either, 128 words of eight bits each or 64 words of 16 bits each. The EEPROM is optimized for industrial and commercial applications where low-power and low-voltage operations are essential. The EEPROM is available in a variety of space-saving packaging options at 1.8 (VCC = 1.8V to 5.5V). The three-wire serial interface consists of a data input, output, and a shift clock. All programming cycles are completely self-timed, and no separate erase cycle is required before write.
