PRODUCT DESCRIPTION  
The SST29SF512/010/020/040 and SST29VF512/010/  
020/040 are 64K x8 / 128K x8 / 256K x8 / 512K x8 CMOS  
Small-Sector Flash (SSF) manufactured with SST’s propri-  
etary, 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 SST29SFxxx devices write  
(Program or Erase) with a 4.5-5.5V power supply. The  
SST29VFxxx devices write (Program or Erase) with a 2.7-  
3.6V power supply. These devices conform to JEDEC stan-  
dard pinouts for x8 memories.  
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 for any given voltage range, the Super-  
Flash 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 appli-  
cations.  
Featuring high performance Byte-Program, the  
SST29SFxxx and SST29VFxxx devices provide a maxi-  
mum Byte-Program time of 20 µsec. To protect against  
inadvertent write, they have on-chip hardware and Soft-  
ware Data Protection schemes. Designed, manufactured,  
and tested for a wide spectrum of applications, these  
devices are offered with a guaranteed endurance of at least  
10,000 cycles. Data retention is rated at greater than 100  
years.  
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  
SST29SFxxx and SST29VFxxx devices are offered in 32-  
pin PLCC and 32-pin TSOP packages. A 600 mil, 32-pin  
PDIP is also offered for SST29SFxxx devices. See Figures  
1, 2, and 3 for pinouts.  
The SST29SFxxx and SST29VFxxx devices are suited for  
applications that require convenient and economical updat-  
ing of program, configuration, or data memory. For all sys-  
tem applications, they significantly improve performance
