PRODUCT DESCRIPTION
The SST49LF080A flash memory device is designed to
interface with the LPC bus for PC and Internet Appliance
application in compliance with Intel Low Pin Count (LPC)
Interface Specification 1.0. Two interface modes are sup-
ported: LPC mode for in-system operations and Parallel
Programming (PP) mode to interface with programming
equipment.
The SST49LF080A flash memory device is manufactured
with SST’s proprietary, high-performance SuperFlash
Technology. The split-gate cell design and thick-oxide tun-
neling injector attain better reliability and manufacturability
compared with alternate approaches. The SST49LF080A
device significantly improves performance and reliability,
while lowering power consumption. The SST49LF080A
device writes (Program or Erase) with a single 3.0-3.6V
power supply. It uses less energy during Erase and Pro-
gram than alternative flash memory technologies. The total
energy consumed is a function of the applied voltage, cur-
rent and time of application. For any give 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 memory technologies. The SST49LF080A product
provides a maximum Byte-Program time of 20 μsec. The
entire memory can be erased and programmed byte-by-
byte typically in 16 seconds when using status detection
features such as Toggle Bit or Data# Polling to indicate the
completion of Program operation. The SuperFlash technol-
ogy provides fixed Erase and Program time, independent
of the number of Erase/Program cycles that have per-
formed. Therefore the system software or hardware does
not have to be calibrated or correlated to the cumulative
number of Erase cycles as is necessary with alternative
flash memory technologies, whose Erase and Program
time increase with accumulated Erase/Program cycles.
To meet high density, surface mount requirements, the
SST49LF080A device is offered in 32-lead TSOP and 32-
lead PLCC packages. See Figures 1 and 2 for pin assign-
ments and Table 1 for pin descriptions.
