The BR9016 are serial EEPROMs that can be connected directly to a
serial port and can be erased and written electrically. 
Writing and reading is performed in word units, using four types of
operation commands. Communication occurs though CS, SK, DI, and DO
pins, WC pin control is used to initiate a write disabled state,
enabling these EEPROMs to be used as one-time ROMs. During writing,
operation is checked via the internal status check.
