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 involves only resetting bits to 0 that had
previously been set to 1. The following are times this use case might occur:
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
Table 13: AC characteristics (50 MHz
operation)).
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

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, Stand-by Power and Deep Power-Down modes
When Chip Select (S) is Low, the device is enabled, and in the Active Power mode.
When Chip Select (S) is High, the device is disabled, but could remain in the Active Power
mode until all internal cycles have completed (Program, Erase, Write). The device then goes
in to the Stand-by Power mode. The device consumption drops to I
The Deep Power-down mode is entered when the specific instruction (the Enter Deep
Power-down Mode (DP) instruction) is executed. The device consumption drops further to

While in the Deep Power-down mode, the device ignores all Write, Program and Erase

The designer is programming the device for the first time;
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;
The designer knows that the change involves only 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.
