64 Mbit (x16) Multi-Purpose Flash Plus
SST39VF6401B / SST39VF6402B
Not Recommended for New Designs
The SST39VF6401B / SST39VF6402B devices are 4M x16, CMOS Multi-Purpose
Flash Plus (MPF+) manufactured with proprietary, high performance CMOS
SuperFlash technology. The split-gate cell design and thick-oxide tunneling injec-
tor attain better reliability and manufacturability compared with alternate
approaches. The SST39VF6401B / SST39VF6402B write (Program or Erase)
with a 2.7-3.6V power supply. These devices conform to JEDEC standard pinouts
for x16 memories and are command set compatible with other Flash devices,
enabling customers to save time and resources in implementation.

Functions
AMS1-A0
Address Inputs
To provide memory addresses.
During Sector-Erase AMS-A11 address lines will select the sector.
During Block-Erase AMS-A15 address lines will select the block.
DQ15-DQ0 Data Input/output To output data during Read cycles and receive input data during Write cycles.
Data is internally latched during a Write cycle.
The outputs are in tri-state when OE# or CE# is high.
WP#
Write Protect
To protect the top/bottom boot block from Erase/Program operation when
grounded.
RST#
Reset
To reset and return the device to Read mode.
CE#
Chip Enable
To activate the device when CE# is low.
OE#
Output Enable To gate the data output buffers.
WE#
Write Enable
To control the Write operations.
VDD Power Supply To provide power supply voltage: 2.7-3.6V
VSS Ground
NC No Connection Unconnected pins.

Product Identification
The Product Identification mode identifies the devices as the SST39VF6401B and SST39VF6402B,
and the manufacturer as SST. This mode may be accessed through software operations. 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 6 for software operation, Figure
11 for the Software ID Entry and Read timing diagram and Figure 21 for the Software ID Entry com-
mand 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 accomplished 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 inad-
vertent transient condition that apparently causes the device to behave abnormally, e.g., not read cor-
rectly. Please note that the Software ID Exit/CFI Exit command is ignored during an internal Program
or Erase operation. See Table 6 for software command codes, Figure 13 for timing waveform, and Fig-
ures 21 and 22 for flowcharts.
