8μA max)  8-byte Page Write Mode ̶ Partial Page Writes Allowed  Random and Sequential Read Modes  Self-timed Write Cycle Within 5ms max  High Reliability ̶ Endurance: 1,000,000 Write Cycles ̶ Data Retention: 100 Years  Green Package Options (Lead-free/Halide-free/RoHS Compliant) ̶ 8-lead SOIC, 8-lead TSSOP, 8-pad UDFN, 8-lead PDIP(1), 5-lead SOT23, and 8-ball VFBGA  Die Sale Options: Wafer Form and Tape and Reel 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.
Note: 1.
