The OOPic boards have I�C Bus Seria lEEPROM.� EEPROM (electrically erasable programmable read-only memory) is user-modifiable read-only memory (ROM) that can be erased and reprogrammed.� The OOPic I, II, and II+ come with 8K x 8 (64K bit) EEPROM in EO and an open socket in E1 that additional EEPROM can be added to.� The OOPic-R has only one bank for EEPROM and comes with a� 8K x 8 (64K bit) chip.� This is a EEPROM IC SERIAL, 32KX8 64K chip.� For more information about OOPic Memory see our PIC page.
