Enhanced Factory Program command
The Enhanced Factory Program command can be used to program large streams of data
within any one block. It greatly reduces the total programming time when a large number of
words are written to a block at any one time.
The use of the Enhanced Factory Program command requires certain operating conditions.

●
Dual operations are not supported during the Enhanced Factory Program operation and the
command cannot be suspended.
For optimum performance the Enhanced Factory Program commands should be limited to a
maximum of 100 program/erase cycles per block. If this limit is exceeded the internal
algorithm will continue to work properly but some degradation in performance is possible.
Typical Program times are given in
Factory Program operation will abort, the data in the block will not be changed and the
Status Register will output the error.
The Enhanced Factory Program command has four phases: the Setup Phase, the Program
Phase to program the data to the memory, the Verify Phase to check that the data has been
correctly programmed and reprogram if necessary and the Exit Phase. Refer to
Factory Program
Setup Phase
The Enhanced Factory Program command requires two Bus Write operations to initiate the
command.

The Status Register P/E.C. SR7 should be read to check that the P/E.C. is ready. After the
confirm command is issued, read operations output the Status Register data. The read
Status Register command must not be issued as it will be interpreted as data to program.
