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 prote.
