Rob,

For your supported table: the Ramtron FM24C256-G works with this library. I'm using it in several projects and It's *much cheaper than the Fujitsu devices. Despite the datasheet stating Vcc=4.7-5.5V I've only ever used the device with an ESP32 and ESP8266 at 3.3V.

It does not have a device register so there's no device metadata.
It does not support sleep.

Standby current 100uA
Active current SCL=100kHz 200uA, SCL=400kHz 500uA, SCL=1MHz 1.2mA

Will not make a new release for it, but will merge develop with master this week.
I might add some other minor refactor.
