PRODUCT DESCRIPTION

The SST39SF512/010 are CMOS Multi-Purpose Flash

(MPF) manufactured with SST’s proprietary, high perfor-

mance CMOS SuperFlash technology. The split-gate cell

design and thick oxide tunneling injector attain better reli-

ability and manufacturability compared with alternate

approaches. The SST39SF512/010 devices write (Pro-

gram or Erase) with a 5.0V-only power supply. The

SST39SF512/010 device conforms to JEDEC standard

pinouts for x8 memories.

function of the applied voltage, current, and time of applica-

tion. 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 technolo-

gies. These devices also improve flexibility while lowering

the cost for program, data, and configuration storage appli-

cations.

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.

Featuring high performance Byte-Program, the

SST39SF512/010 devices provide a maximum Byte-Pro-

gram time of 30 µsec. These devices use Toggle Bit or

Data# Polling to indicate the completion of Program opera-

tion. To protect against inadvertent write, they have on-chip

hardware and Software Data Protection schemes.

Designed, manufactured, and tested for a wide spectrum of

applications, these devices 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

SST39SF512/010 are offered in 32-pin PLCC packages,

32-pin TSOP, and a 600 mil, 32-pin PDIP is also available.

See Figures 1, 2, and 3 for pinouts.

The SST39SF512/010 devices are suited for applications

that require convenient and economical updating of pro-

gram, configuration, or data memory. For all system appli-

cations, they significantly improve performance and

reliability, while lowering power consumption. They inher-

ently use less energy during erase and program than alter-

native flash technologies. The total energy consumed is a

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#
