The chips I used in the past didn't need to get refreshed and they were pin
compatible with an eeprom I was using in a PIC circuit with an i2c
interface.  They were basically identical with the exception that they don't
wear out before the sun expands and swallows the earth, and they can be
clocked many times faster than the i2c and spi spec.
