PRODUCT DESCRIPTION
alternative flash technologies. The total energy con-
sumed is a function of the applied voltage, current, and
timeofapplication.Sinceforanygivenvoltagerange,the
SuperFlashtechnologyuseslesscurrenttoprogramand
has a shorter erase time, the total energy consumed
during any Erase or Program operation is less than
alternative flash technologies. The SST39LH160Q/
LH160 also improve flexibility while lowering the cost for
program, data, and configuration storage applications.
The SST39LH160Q/LH160 devices are 1M x 16 CMOS
Multi-Purpose Flash (MPF) manufactured with SST’s
proprietary, high performance CMOS SuperFlash tech-
nology. The split-gate cell design and thick oxide tunnel-
ing injector attain better reliability and manufacturability
compared with alternate approaches. The
SST39LH160Q/LH160 write (Program or Erase) with a
3.0-3.6Vpowersupply.TheSST39LH160Q/LH160con-
form to JEDEC standard pinouts for x16 memories.

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.
Featuring high performance Word Program, the
SST39LH160Q/LH160 devices provide a typical word-
program time of 14 µsec. The entire memory can typi-
cally be erased and programmed word-by-word in 15
seconds, when using interface features such as Toggle
BitorData#PollingtoindicatethecompletionofProgram
operation. To protect against inadvertent write, the
SST39LH160Q/LH160haveon-chiphardwareandsoft-
ware data protection schemes. Designed, manufac-
tured,andtestedforawidespectrumofapplications,the
SST39LH160Q/LH160 are offered with a guaranteed
endurance of 10,000 cycles. Data retention is rated at
greater than 100 years.
To meet high density, surface mount requirements, the
SST39LH160Q/LH160 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 issued to the
deviceusingstandardmicroprocessorwritesequences.
A command is loaded 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 SST39LH160Q/LH160 devices are suited for appli-
cationsthatrequireconvenientandeconomicalupdating
of program, configuration, or data memory. For all sys-
tem applications, the SST39LH160Q/LH160 signifi-
cantly improve performance and reliability, while lower-
ing power consumption. The SST39LH160Q/LH160 in-
