Ordering number: ENA2069 LE24CBK23MC CMOS IC Dual port EEPROM Two Wire Serial Interface (2K+2K EEPROM) http://onsemi.
com Overview The dual port EEPROM series consists of two independent banks, and each bank can be controlled separately using dedicated control pins.
The two banks can each be controlled separately, but share the internal power supply system.
In addition, this product uses a 2-wire serial interface, and is the optimal device for realizing substantial reductions in system cost and mounting area, as well as low power consumption.
This product also incorporates a combine mode that allows the two-bank configuration (2K bits + 2K bits) to be used as a pseudo-one-bank configuration...
