• 2KBEEPROM存储器：AT24HC02B 汽车级
• 4KBEEPROM存储器：AT24HC04B 汽车级

The AT24HC02B/04B provides 2048/4096 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as 256/512 words of 8 bits each. The device is optimized for use in many automotive applications where low-power and low-voltage operation are essential. The AT24HC02B/04B is available in space-saving 8-lead JEDEC SOIC and 8-lead TSSOP packages and is accessed via a two-wire serial interface. In addition, the entire family is available in 2.5V (2.5V to 5.5V) versions.
