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.
If the block being programmed is protected then the Program operation will abort, the data
in the block will not be changed and the Status Register will output the error.
The use of the Enhanced Factory Program command requires certain operating conditions.
VPP must be set to VPPH
VDD must be within operating range
Ambient temperature TA must be 30 °C ± 10°C
The targeted block must be unlocked
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 Table 16.
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 Table 7:
6.3.1
Setup Phase
The Enhanced Factory Program command requires two Bus Write operations to initiate the
command.
The first bus cycle sets up the Enhanced Factory Program command.
The second bus cycle confirms the command.
The Status Register P/E.C. Bit 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.
If the second bus cycle is not EFP confirm(D0h), the Status Register bits SR4 and SR5 are
set and the command will be aborted.
VPP value must be in the VPPH range during the Confirm command, otherwise SR4 and SR3
will be set and the command will be aborted.
