AT24C01B
Description
The AT24C01B provides 1024 bits of serial electrically erasable and programmable
read-only memory (EEPROM) organized as 128 words of 8 bits each. The device is
optimized for use in many industrial and commercial applications where low-power
and low-voltage operation are essential. The AT24C01B is available in space-saving
8-lead PDIP, 8-lead JEDEC SOIC, 8-lead Ultra Thin Mini-MAP (MLP 2x3) , 5-lead
SOT23, 8-lead TSSOP, and 8-ball dBGA2 packages and is accessed via a Two-wire
serial interface. In addition, the AT24C01B is available in 1.8V (1.8V to 5.5V) version.
Not Recommended
for New Design.
Replaced by AT24C01C.
