PRODUCT DESCRIPTION  
The SST39VF088 device is a 1M x8 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 SST39VF088 writes (Program or Erase)  
with a 2.7-3.6V power supply. It conforms to JEDEC stan-  
dard pinouts for x8 memories.  
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 technologies. They  
also improve flexibility while lowering the cost for program,  
data, and configuration storage applications.  
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.  
Featuring high performance Byte-Program, the  
SST39VF088 device provides a typical Byte-Program time  
of 14 µsec. The devices use Toggle Bit or Data# Polling to  
indicate 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.  
To meet high density, surface mount requirements, the  
SST39VF088 is offered in 48-lead TSOP packaging. See  
Figure 1 for pin assignments.  
The SST39VF088 device is suited for applications that  
require convenient and economical 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 Erase and Program than alternative flash  
technologies. The total energy consumed is a function of  
the applied voltage, current, and time of application. Since
