Latched Address and Data  
PRODUCT DESCRIPTION  
The SST39LF/VF100 devices are 64K 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  
energy consumed during any Erase or Program operation  
is less than alternative flash technologies. The SST39LF/  
VF100 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.  
alternate  
approaches.  
The  
SST39LF100  
and  
SST39VF100 write (Program or Erase) with a single volt-  
age power supply of 3.0-3.6V and 2.7-3.6V, respectively.  
Featuring high performance Word-Program, the SST39LF/  
VF100 devices provide a typical Word-Program time of 14  
µsec. The devices use Toggle Bit or Data# Polling to detect  
the completion of the Program or Erase operation. To pro-  
tect against inadvertent write, the SST39LF/VF100 have  
on-chip hardware and software data protection schemes.  
Designed, manufactured, and tested for a wide spectrum of  
applications, the SST39LF/VF100 are offered with a guar-  
anteed endurance of 10,000 cycles. Data retention is rated  
at greater than 100 years.  
To meet surface mount requirements, the SST39LF/VF100  
are offered in 40-lead TSOP and 48-ball TFBGA packages.  
See Figure 1 for pinout.  
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.  
The SST39LF/VF100 devices are suited for applications  
that require convenient and economical updating of pro-  
gram, configuration, or data memory. For all system appli-  
cations, the SST39LF/VF100 significantly improve  
performance and reliability, while lowering power consump-  
tion. The SST39LF/VF100 inherently use less energy dur-  
ing Erase and Program than alternative flash technologies.  
The total energy consumed is a function of the applied volt-  
age, current, and time of application. Since for any given  
voltage range, the SuperFlash technology uses less cur-  
rent to program and has a shorter erase time, the total
