Extended Quad Input Fast Read Operation (EBh)

This operation is similar to the fast read operation except that the data and addresses are shifted in and out on the DATA0, DATA1, DATA2, and DATA3 pins.

Figure 13. Extended Quad Input Fast Read Operation Timing Diagram

When the device reaches the highest address, the address counter restarts at the beginning of the same die, allowing the read sequence to continue indefinitely. A complete device reading is done by executing the read operation:

  • two times for EPCQ-L512 devices
  • four times for EPCQ-L1024 devices
