ATMEL MEMORY AUTHORIZED DISTRIBUTOR

The Atmel 1 Kbit two-wire serial EEPROM with full memory write-protect, supports up to eight devices on a single two-wire bus. The EEPROM is organized as 128 words x 8 bits. Optimized for industrial and commercial applications where low-power and low-voltage operations are essential. The EEPROM is available in space-saving packaging options, and 1.8V (1.8V to 5.5V) versions.
