Description

The Atmel?AT24CS01 and AT24CS02 provides 1024/2048 bits of Serial Electrically Erasable and Programmable Read-only Memory (EEPROM) organized as 128/256 words of eight bits each. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The AT24CS01/02 is available in space-saving, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-pad UDFN and 5-lead SOT23 packages and is accessed via a 2-wire serial interface. In addition, both devices fully operate from 1.7V to 5.5V VCC.
