AT24C128B 128Kbit,2线串行EEPROM存储器

128Kbit, 2-Wire Bus Serial EEPROM with full memory Write Protect, supports up to 8 devices on single 2-Wire bus.

The AT24C128B provides 131,072 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as 16,384 words of 8 bits each. The device’s cascadable feature allows up to eight devices to share a common two-wire bus. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The devices are available in space-saving 8-lead JEDEC PDIP, 8-lead JEDEC SOIC, 8-lead Ultra Thin Mini MAP, 8-lead Ultra Lead Frame Land Grid Array (ULA), 8-lead TSSOP, and 8-ball dBGA2 packages. In addition, the entire family is available in a 1.8V (5.5V to 3.6V) version.
