描述 Description

The Atmel® AT24CS04 and AT24CS08 provides 4096/8192 bits of Serial Electrically Erasable and Programmable LButtonRead-only Memory (EEPROM) organized as 512/1024 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 AT24CS04/08 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.
