8 Mbit (x16) Multi-Purpose Flash Plus
A Microchip Technology Company
SST39VF801C / SST39VF802C / SST39LF801C / SST39LF802C
Data Sheet
Product Description
The SST39VF801C/802C and SST39LF801C/802C devices are 512K x16 CMOS Multi-Purpose Flash
Plus (MPF+) manufactured with SST 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 SST39VF801C/802C and SST39LF801C/802C write (Program
or Erase) with a 2.7-3.6V power supply. These devices conform to JEDEC standard pinouts for x16
memories.
Featuring high performance Word-Program, the SST39VF801C/802C and SST39LF801C/802C
devices provide a typical Word-Program time of 7 μsec. These devices use Toggle Bit, Data# Polling,
or the RY/BY# pin to indicate the completion of Program operation. 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 typical
endurance of 100,000 cycles. Data retention is rated at greater than 100 years.
The SST39VF801C/802C and SST39LF801C/802C devices are suited for applications that require
convenient and economical updating of program, configuration, or data memory. For all system appli-
cations, they significantly improve performance and reliability, while lowering power consumption. They
inherently use less energy during Erase and Program than alternative flash technologies. 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 operation is less than alternative flash
technologies. These devices also improve flexibility while lowering the cost for program, data, and con-
figuration storage applications.
The SuperFlash technology provides fixed Erase and Program 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 Pro-
gram times increase with accumulated Erase/Program cycles.
To meet high density, surface mount requirements, the SST39VF801C/802C and SST39LF801C/802C
are offered in 48-lead TSOP, 48-ball TFBGA, and 48-ball WFBGA packages. See Figures 2, 3, and 4
for pin assignments.
