Power switch integrated triple port EEPROM
Two Wire Serial Interface
(2K+2K EEPROM)
Overview
The power switch integrated triple port EEPROM series consists of two independent banks, and each bank can be
controlled separately using dedicated control pins. The EEPROM also features a control port, which is a third pin
separate from the pins used for the banks, and by accessing the memory areas from this control port, the two-bank
configuration (2K bits + 2K bits) can be used as a pseudo-one-bank configuration (4K bits). Together with the 16-byte
page write function, this enables a reduction in the number of factory write processes.
Furthermore, the EEPROM has a configuration area which is separate from the 2K-bit + 2K-bit area, and by using the
settings stored in this configuration area, it is possible to change the slave address for each port and to set read/write
protection for each port.
The EEPROM also incorporates a power switch circuit with reverse current blocking diodes, supporting different
power voltages among three ports. This product incorporates SANYO's 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.
