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 (4K bits) by setting the COBM# pin to the low level. Together with the 16-byte
page write function, this enables a reduction in the number of factory write processes.
This product incorporates high performance CMOS EEPROM technology and realizes high-speed operation and
high-level reliability. The interface of this product is compatible with the I2C bus protocol, making it ideal as a
nonvolatile memory for small-scale parameter storage.
In addition, this product also supports DDC2TM, so it can also be used as an EDID data storage memory for display
equipment.
