PRODUCT DESCRIPTION
The SST39LF/VF160 devices are 1M x16 CMOS Multi-
Purpose Flash (MPF) manufactured with SST’s proprietary,
high performance CMOS SuperFlash technology. The
split-gate cell design and thick oxide tunneling injector
attain better reliability and manufacturability compared with
alternate approaches. The SST39LF160 write (Program or
Erase) with a 3.0-3.6V power supply. The SST39VF160
write (Program or Erase) with a 2.7-3.6V power supply.
These devices conform to JEDEC standard pinouts for x16
memories.
Featuring high performance Word-Program, the SST39LF/
VF160 devices provide a typical Word-Program time of 14
µsec.These devices use Toggle Bit or Data# Polling to indi-
cate the completion of Program operation. To protect
against inadvertent write, they have on-chip hardware and
Software Data Protection schemes. Designed, manufac-
tured, 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.
The SST39LF/VF160 devices are suited for applications
that require convenient and economical updating of pro-
gram, configuration, or data memory. For all system appli-
cations, they significantly improve performance and
reliability, while lowering power consumption. They inher-
ently use less energy during Erase and Program than alter-
native flash technologies. The total energy consumed is a
function of the applied voltage, current, and time of applica-
tion. Since for any given voltage range, the SuperFlash

technology uses less current to program and has a shorter
erase time, the total energy consumed during any Erase or
Program operation is less than alternative flash technolo-
gies. These devices also improve flexibility while lowering
the cost for program, data, and configuration storage appli-
cations.
The SuperFlash technology provides fixed Erase and Pro-
gram times, independent of the number of Erase/Program
cycles that have occurred. Therefore the system software
or hardware does not have to be modified or de-rated as is
necessary with alternative flash technologies, whose Erase
and Program times increase with accumulated Erase/Pro-
gram cycles.
To meet high density, surface mount requirements, the
SST39LF/VF160 are offered in 48-lead TSOP and 48-ball
TFBGA packages. See Figure 1 for pinouts.
Device Operation
Commands are used to initiate the memory operation func-
tions of the device. Commands are written to the device
using standard microprocessor write sequences. A com-
mand 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.
