PRODUCT DESCRIPTION

The SST39LF512, SST39LF010, SST39LF020, SST39LF040

and SST39VF512, SST39VF010, SST39VF020, SST39VF040

are 64K x8, 128K x8, 256K x8 and 5124K x8 CMOS Multi-Pur-

pose Flash (MPF) manufactured with SST’s proprietary, high per-

formance CMOS SuperFlash technology. The split-gate cell

design and thick-oxide tunneling injector attain better reliability and

manufacturability compared with alternate approaches. The

SST39LF512/010/020/040 devices write (Program or Erase) with

a 3.0-3.6V power supply. The SST39VF512/010/020/040 devices

write with a 2.7-3.6V power supply. The devices conform to

JEDEC standard pinouts for x8 memories.

Featuring high performance Byte-Program, the

SST39LF512/010/020/040 and SST39VF512/010/020/

040 devices provide a maximum Byte-Program time of 20

µsec. These devices use Toggle Bit or Data# Polling to indi-

cate the completion of Program operation. To protect

against inadvertent write, they have on-chip hardware and

Software Data Protection schemes. Designed, manufac-

tured, and tested for a wide spectrum of applications, they

are offered with a guaranteed typical endurance of

100,000 cycles. Data retention is rated at greater than 100

years.

The SST39LF512/010/020/040 and SST39VF512/010/

020/040 devices are suited for applications that require

convenient and economical updating of program, configu-

ration, or data memory. For all system applications, they

significantly improves performance and reliability, while low-

ering power consumption. They inherently use less energy

during Erase and Program than alternative flash technolo-

gies. The total energy consumed 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 oper-

ation is less than alternative flash technologies. These

devices 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 SST39LF512/

010/020/040 and SST39VF512/010/020/040 devices are

offered in 32-lead PLCC and 32-lead TSOP packages. The

SST39LF/VF010 and SST39LF/VF020 are also offered in

a 48-ball TFBGA package. See Figures 2, 3, 4, and 5 for

pin assignments.
