PRODUCT DESCRIPTION  
The SST28SF/VF040A are 512K x8 bit CMOS Sector-  
Erase, Byte-Program EEPROMs. The SST28SF/VF040A  
are manufactured using SST’s proprietary, high perfor-  
mance CMOS SuperFlash EEPROM Technology. The  
split-gate cell design and thick oxide tunneling injector  
attain better reliability and manufacturability compared with  
alternative approaches. The SST28SF/VF040A erase and  
program with a single power supply. The SST28SF/  
VF040A conform to JEDEC standard pinouts for byte wide  
memories and are compatible with existing industry stan-  
dard flash EEPROM pinouts.  
cations, the SST28SF/VF040A significantly improve  
performance and reliability, while lowering power consump-  
tion when compared with floppy diskettes or EPROM  
approaches. Flash EEPROM technology makes possible  
convenient and economical updating of codes and control  
programs on-line. The SST28SF/VF040A improve flexibil-  
ity, while lowering the cost of program and configuration  
storage application.  
The functional block diagram shows the functional blocks of  
the SST28SF/VF040A. Figures 1, 2, and 3 show the pin  
assignments for the 32-lead PLCC, 32-lead TSOP, and 32-  
pin PDIP packages. Pin descriptions and operation modes  
are described in Tables 2 through 5.  
Featuring high performance programming, the SST28SF/  
VF040A typically Byte-Program in 35 µs. The SST28SF/  
VF040A typically Sector-Erase in 2 ms. Both Program and  
Erase times can be optimized using interface features such  
as Toggle bit or Data# Polling to indicate the completion of  
the Write cycle. To protect against an inadvertent write, the  
SST28SF/VF040A have on chip hardware and Software  
Data Protection schemes. Designed, manufactured, and  
tested for a wide spectrum of applications, the SST28SF/  
VF040A are offered with a guaranteed sector endurance of  
10,000 cycles. Data retention is rated greater than 100  
years.  
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.  
Note, during the Software Data Protection sequence the  
addresses are latched on the rising edge of OE# or CE#,  
whichever occurs first.  
The SST28SF/VF040A are best suited for applications that  
require reprogrammable nonvolatile mass storage of pro-  
gram, configuration, or data memory. For all system appli-
