| Features • Low voltage operation ̶ 1.7V (VCC = 1.7V to 3.6V) • Internally organized 128 x 8 (1K) or 256 x 8 (2K) • I2C-Compatible (2-wire) serial interface • Schmitt Triggers, filtered inputs for noise suppression • Bidirectional data transfer protocol • 400kHz (1.7V) and 1MHz (2.5V) compatibility • Write Protect pin for full array hardware data protection • Ultra low active current (1mA max) and standby current (0.8μA 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 available 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. |
