device to read mode within T
can be V
mand sequence.
Common Flash Memory Interface (CFI)
The SST39VF1601C/1602C also contain the CFI informa-
tion to describe the characteristics of the device. In order
to enter the CFI Query mode, the system writes a three-
byte sequence, same as product ID entry command with
98H (CFI Query command) to address 555H in the last
byte sequence. Additionally, the system can use the one-
byte sequence with 55H on the Address and 89H on the
Data Bus to enter the CFI Query mode. Once the device
enters the CFI Query mode, the system can read CFI data
at the addresses given in Tables 8 through 10. The system
must write the CFI Exit command to return to Read mode
from the CFI Query mode.
Product Identification
The Product Identification mode identifies the devices as
the SST39VF1601C, SST39VF1602C, and manufacturer
as SST. This mode may be accessed software opera-
tions. Users may use the Software Product Identification
operation to identify the part (i.e., using the device ID)
when using multiple manufacturers in the same socket.
For details, see Table 7 for software operation, Figure 14
for the Software ID Entry and Read timing diagram and
Figure 24 for the Software ID Entry command sequence
flowchart.

Product Identification Mode Exit/
CFI Mode Exit
In order to return to the standard Read mode, the Software
Product Identification mode must be exited. Exit is accom-
plished by issuing the Software ID Exit command
sequence, which returns the device to the Read mode.
This command may also be used to reset the device to the
Read mode after any inadvertent transient condition that
apparently causes the device to behave abnormally, e.g.,
not read correctly. Please note that the Software ID Exit/
CFI Exit command is ignored during an internal Program or
Erase operation. See Table 7 for software command
codes, Figure 16 for timing waveform, and Figure 25 for
flowcharts.
Security ID
The SST39VF1601C/1602C devices offer a 136 Word
Security ID space. The Secure ID space is divided into two
segments—one factory programmed segment and one
user programmed segment. The first segment is pro-
grammed and locked at SST with a random 128-bit num-
ber. The user segment, with a 128 word space, is left un-
programmed for the customer to program as desired.
To program the user segment of the Security ID, the user
must use the Security ID Word-Program command. To
detect end-of-write for the SEC ID, read the toggle bits. Do
not use Data# Polling. Once this is complete, the Sec ID
should be locked using the User Sec ID Program Lock-Out.
This disables any future corruption of this space. Note that
regardless of whether or not the Sec ID is locked, neither
Sec ID segment can be erased.
The Secure ID space can be queried by executing a three-
byte command sequence with Enter Sec ID command
(88H) at address 555H in the last byte sequence. To exit
this mode, the Exit Sec ID command should be executed.
Refer to Table 7 for more details.
