A fast way to modify data
The Page Program (PP) instruction provides a fast way of modifying data (up to 256
contiguous bytes at a time), provided that it only involves resetting bits to 0 that had
previously been set to ‘1’.
This might be:
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

Polling during a write, program or erase cycle
A further improvement in the write, program or erase time can be achieved by not waiting for
the worst case delay (t
status register so that the application program can monitor its value, polling it to establish
when the previous cycle is complete.
Reset
An internal power on reset circuit helps protect against inadvertent data writes. Addition
protection is provided by driving Reset (Reset) Low during the power-on process, and only
driving it High when V
Active power, standby power and deep power-down modes
When Chip Select (S) is Low, the device is selected, and in the active power mode.
When Chip Select (S) is High, the device is deselected, but could remain in the active power
mode until all internal cycles have completed (program, erase, write). The device then goes
in to the standby power mode. The device consumption drops to I
The deep power-down mode is entered when the specific instruction (the deep power-down
(DP) instruction) is executed. The device consumption drops further to I
remains in this mode until another specific instruction (the release from deep power-down
and read electronic signature (RES) instruction) is executed.
All other instructions are ignored while the device is in the deep power-down mode. This can
be used as an extra software protection mechanism, when the device is not in active use, to
protect the device from inadvertent write, program or erase instructions.
when the designer is programming the device for the first time
when the designer knows that the page has already been erased by an earlier page
erase (PE) or sector erase (SE) instruction. This is useful, for example, when storing a
fast stream of data, having first performed the erase cycle when time was available
when the designer knows that the only changes involve resetting bits to 0 that are still
set to ‘1’. When this method is possible, it has the additional advantage of minimizing
the number of unnecessary erase operations, and the extra stress incurred by each
page.
