Quad Input Fast Program

The Quad Input Fast Program (QIFP) instruction is very similar to the Dual Input Fast

Program (DIFP) instruction, except that the data are entered on four pins (pin DQ0, pin

DQ1, pin W/VPP/DQ2 and pin HOLD/ (DQ3) instead of only two. Inputting the data on four

pins instead of two doubles the data transfer bandwidth compared to the Dual Input Fast

Program (DIFP) instruction.

The Quad Input Fast Program (QIFP) instruction is entered by driving Chip Select (S) Low,

followed by the instruction code, three address bytes on Serial Data input (DQ0), and at

least one data byte on Serial Data I/Os (DQ0, DQ1, DQ2, DQ3).

If the 8 least significant address bits (A7-A0) are not all zero, all transmitted data that go

beyond the end of the current page are programmed from the start address of the same

page (from the address whose 8 least significant bits (A7-A0) are all zero). Chip Select (S)

must be driven Low for the entire duration of the sequence.

If more than 256 bytes are sent to the device, previously latched data are discarded and the

last 256 data bytes are guaranteed to be programmed correctly within the same page. If less

than 256 data bytes are sent to device, they are correctly programmed at the requested

addresses without having any effects on the other bytes in the same page.

For optimized timings, it is recommended to use the Quad Input Fast Program (QIFP)

instruction to program all consecutive targeted bytes in a single sequence rather to using
