• 128KBEEPROM存儲器：AT24C128 汽車級
• 256KBEEPROM存儲器：AT24C256 汽車級

The AT24C128/256 provides 131,072/262,144 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 16,384/32,768 words of 8 bits each. The device’s cascadable feature allows up to 4 devices to share a common Two-wire bus. The device is optimized for use in many automotive applications where low power and low voltage operation are essential. The AT24C128 is available in space-saving 8-lead JEDEC SOIC and 8-lead TSSOP packages. The AT24C256 is available in a space-saving 8-lead JEDEC SOIC package. In addition, the entire family is available in 2.7V (2.7V to 5.5V) version.
