EOL Data Sheet
Successive Reads
An Alternative means for determining an end of a Write
operation is by reading the same address for two consecu-
tive data matches.
Product Identification
The Product Identification mode identifies the device
as SST28SF/VF040A and the manufacturer as SST.
This mode may be accessed by hardware and soft-
ware operations. The hardware operation is typically
used by an external programmer to identify the correct
algorithm for the SST28SF/VF040A. Users may wish

to use the software operation to identify the device
(i.e., using the device ID). For details see Table 3 for
the hardware operation and Figure 19 for the software
operation. The manufacturer’s and device IDs are the
same for both operations.
