Description
The Atmel^® AT24C01D/02D provides 1,024/2,048 bits of Serial Electrically
Erasable and Programmable Read-Only Memory (EEPROM) organized as
128/256 words of eight bits each. The device’s cascadable feature allows up to
eight devices to share a common 2-wire bus. These device are optimized for use
in many industrial and commercial applications where low-power and low-voltage
operation are essential. Both devices are available in space-saving 8-lead SOIC,
8-lead TSSOP, 8-pad UDFN, 8-lead PDIP,⁽¹⁾ 5-lead SOT23, and
8-ball VFBGA packages. The entire family of packages operates from 1.7V to
3.6V.
