8k, 16k bit EEPROMs for direct
connection to serial ports

BR9016AF-W / BR9016ARFV-W / BR9016ARFVM-W
The BR9080A and BR9016A series 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.
!
Applications
Movie, camera, cordless telephones, car stereos, VCRs, TVs, DIP switches, and other battery-powered equipment

Input data are clocked in to DI at the rising edge of the clock (SK).
Output data will toggle on the falling edge of the SK clock.
The WC pin does not have any effect on the READ, EWEN and EWDS operations.
