 		 #180144 - If serial EEPROM not in critical path...
Responding to: ???'s previous message
If the serial EEPROM is not in the critical path of your code from a timing and performance standpoint I would jump right to bit banging. To be honest I find that doing a bit-bang interface to a serial EEPROM is less work than rolling out a driver for an I2C peripheral from scratch using the special function register descriptions from the data sheet. On the other hand if your MCU supplier has a nice working example in an application note then that can save a lot of time.
