Operating features
Page Programming
To program one data byte, two instructions are required: Write Enable (WREN), which is
one byte, and a Page Program (PP) sequence, which consists of four bytes plus data. This
is followed by the internal Program cycle (of duration t
To spread this overhead, the Page Program (PP) instruction allows up to 256 bytes to be
programmed at a time (changing bits from 1 to 0), provided that they lie in consecutive
addresses on the same page of memory.
For optimized timings, it is recommended to use the Page Program (PP) instruction to
program all consecutive targeted bytes in a single sequence versus using several Page
Program (PP) sequences with each containing only a few bytes (see
Sector Erase and Bulk Erase
The Page Program (PP) instruction allows bits to be reset from 1 to 0. Before this can be
applied, the bytes of memory need to have been erased to all 1s (FFh). This can be
achieved either a sector at a time, using the Sector Erase (SE) instruction, or throughout the
entire memory, using the Bulk Erase (BE) instruction. This starts an internal Erase cycle (of
duration t
The Erase instruction must be preceded by a Write Enable (WREN) instruction.
Polling during a Write, Program or Erase cycle
A further improvement in the time to Write Status Register (WRSR), Program (PP) or Erase
(SE or BE) can be achieved by not waiting for the worst case delay (t
Write In Progress (WIP) bit is provided in the Status Register so that the application program
can monitor its value, polling it to establish when the previous Write cycle, Program cycle or
Erase cycle is complete.
Fast Program/Erase mode
The Fast Program/Erase mode is used to speed up programming/erasing. The device
enters the Fast Program/Erase mode during the Page Program, Sector Erase or Bulk Erase
instruction whenever a voltage equal to V
The use of the Fast Program/Erase mode requires specific operating conditions in addition
