PRODUCT DESCRIPTION
Erase and Program than alternative flash technologies.
The total energy consumed is a function of the applied
voltage, current, and time of application. Since for any
givenvoltagerange,theSuperFlashtechnologyusesless
current to program and has a shorter erase time, the total
energyconsumedduringanyEraseorProgramoperation
is less than alternative flash technologies. They also
improveflexibilitywhileloweringthecostforprogram,data,
and configuration storage applications.

TheSST39LF/VF080andSST39LF/VF016devicesare
1M x8 / 2M x8 CMOS Multi-Purpose Flash (MPF)
manufacturedwithSST’sproprietary,highperformance
CMOS SuperFlash technology. The split-gate cell de-
sign and thick oxide tunneling injector attain better
reliabilityandmanufacturabilitycomparedwithalternate
approaches. The SST39LF080/016 write (Program or
Erase) with a 3.0-3.6V power supply. The
SST39VF080/016 write (Program or Erase) with a 2.7-
3.6V power supply. They conform to JEDEC standard
pinouts for x8 memories.

The SuperFlash technology provides fixed Erase and
Program times, independent of the number of Erase/
Program cycles that have occurred. Therefore the sys-
tem software or hardware does not have to be modified
or de-rated as is necessary with alternative flash tech-
nologies, whose Erase and Program times increase
with accumulated Erase/Program cycles.
Featuring high performance Byte-Program, the
SST39LF/VF080andSST39LF/VF016devicesprovide
atypicalByte-Programtimeof14µsec.Thedevicesuse
Toggle Bit or Data# Polling to indicate the completion of
Programoperation.Toprotectagainstinadvertentwrite,
they have on-chip hardware and Software Data Protec-
tion schemes. Designed, manufactured, and tested for
a wide spectrum of applications, these devices are
offered with a guaranteed endurance of 10,000 cycles.
Data retention is rated at greater than 100 years.
To meet high density, surface mount requirements, the
SST39LF/VF080 and SST39LF/VF016 are offered in
40-pin TSOP and 48-ball TFBGA packaging. See
Figures 1 and 2 for pinouts.
Device Operation
Commands are used to initiate the memory operation
functions of the device. Commands are written to the
device using standard microprocessor write se-
quences. A command is written by asserting WE# low
while keeping CE# low. The address bus is latched on
the falling edge of WE# or CE#, whichever occurs last.
The data bus is latched on the rising edge of WE# or
CE#, whichever occurs first.
The SST39LF/VF080 and SST39LF/VF016 devices are
suited for applications that require convenient and eco-
nomical updating of program, configuration, or data
memory. For all system applications, they significantly
improve performance and reliability, while lowering power
consumption. They inherently use less energy during
