PRODUCT DESCRIPTION
The SST39VF800Q/VF800 devices are 512K x 16
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 SST39VF800Q/VF800 write (Program or Erase)
with a 2.7-3.6V power supply. The SST39VF800Q/
VF800 conform to JEDEC standard pinouts for x16
memories.
Featuring high performance word program, the
SST39VF800Q/VF800 devices provide a typical word
program time of 14 µsec. The entire memory can typi-
cally be erased and programmed word-by-word in 8
seconds, when using interface features such as Toggle
Bit or Data# Polling to indicate the completion of Program
operation. To protect against inadvertent write, the
SST39VF800Q/VF800 have on-chip hardware and soft-
ware data protection schemes. Designed, manufac-
tured, and tested for a wide spectrum of applications, the
SST39VF800Q/VF800 are offered with a guaranteed
endurance of 10,000 cycles. Data retention is rated at
greater than 100 years.
The SST39VF800Q/VF800 devices are suited for appli-
cations that require convenient and economical updating
of program, configuration, or data memory. For all sys-
tem applications, the SST39VF800Q/VF800 signifi-
cantly improve performance and reliability, while lower-
ing power consumption. The SST39VF800Q/VF800 in-
• Latched Address and Data
• Fast Sector Erase and Word Program:
- Sector Erase Time: 18 ms (typical)
- Block Erase Time: 18 ms (typical)
- Chip Erase Time: 70 ms (typical)
- Word Program time: 14 µs (typical)
- Chip Rewrite Time: 8 seconds (typical)
• Automatic Write Timing

herently use less energy during Erase and Program than
alternative flash technologies. The total energy con-
sumed is a function of the applied voltage, current, and
time of application. 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 technologies. The SST39VF800Q/
VF800 also improve flexibility while lowering the cost for
program, data, and configuration storage applications.
The SuperFlash technology provides fixed Erase and
Program times, independent of the number of Erase/
Program cycles that have occurred. Therefore the sys-
tem software or hardware does not have to be modified
or de-rated as is necessary with alternative flash tech-
nologies, whose erase and program times increase with
accumulated Erase/Program cycles.
To meet high density, surface mount requirements, the
SST39VF800Q/VF800 are offered in 48-pin TSOP and
48-pin TFBGA packages. See Figures 1 and 2 for
pinouts.
Device Operation
Commands are used to initiate the memory operation
functions of the device. Commands are written to the
device using standard microprocessor write sequences.
A command 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.
