PRODUCT DESCRIPTION
The SST49LF160C flash memory device is designed to
interface with host controllers (chipsets) that support a low-
pin-count (LPC) interface for system firmware applications.
The SST49LF160C device complies with the LPC Interface
Specification. The LPC interface operates with 5 signal pins
versus 32 pins of a 8-bit parallel flash memory. This frees
up pins on the ASIC host controller resulting in lower ASIC
costs and a reduction in overall system costs due to simpli-
fied signal routing.
bit user programmable OTP area enhances the user’s abil-
ity to use new security techniques and implement a new
data protection scheme. The SST49LF160C also provides
general purpose inputs (GPI) for system design flexibility.
The SST49LF160C flash memory device is manufactured
with SST’s proprietary, high-performance SuperFlash tech-
nology. The split-gate cell design and thick-oxide tunneling
injector attain greater reliability and manufacturability com-
pared with alternative technology approaches. The
SST49LF160C device significantly improves performance
and reliability, while lowering power consumption. The
SST49LF160C device writes (Program or Erase) in-system
with a single 3.0-3.6V power supply. It uses less energy
during Erase and Program than alternative flash memory
technologies.
The SST49LF160C uses a 5-signal LPC interface to sup-
port both in-system and rapid factory programming using
programmer equipment. A high voltage pin (WP#/AAI) is
used to enable Auto Address Increment (AAI) mode. The
SST49LF160C offers hardware block protection in addition
to individual block protection via software registers for critical
system code and data. A 256-bit Security ID space with a
64-bit factory pre-programmed unique number and a 192-
