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
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.
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
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.
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.
