EEPROM Serial-2Wire 8Kbit 1K x 8 3.3V 8Pin SOIC
Description
The AT24C02A/04A/08A provides 2048/4096/8192 bits of serial electrically erasable and programmable read only memory EEPROM organized as 256/512/1024 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The AT24C02A/04A/08A is available in space saving 8-pin PDIP, 8-pin, 14-pin SOIC, and 8-pin TSSOP packages and is accessed via a 2-wire serial interface. In addition, the entire family is available in 5.0V 4.5V to 5.5V, 2.7V 2.7V to 5.5V, 2.5V 2.5V to 5.5V and 1.8V 1.8V to 5.5V versions.
