PRODUCT DESCRIPTION
The SST49LF016C flash memory device is designed to
interface with host controllers (chipsets) that support a low-
pin-count (LPC) interface for BIOS applications. The
SST49LF016C device complies with Intel’s LPC Interface
Specification 1.1, supporting Multi-Byte Firmware Memory
Read/Write and LPC Memory Read/Write cycle types.
ity to use new security techniques and implement a new
data protection scheme. The SST49LF016C also provides
general purpose inputs (GPI) for system design flexibility.
The SST49LF016C 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
SST49LF016C device significantly improves performance
and reliability, while lowering power consumption. The
SST49LF016C 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 total energy consumed is a function of
the applied voltage, current and time of application. Since
for any given voltage range, the SuperFlash technology
The SST49LF016C 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
SST49LF016C 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-
bit user programmable OTP area enhances the user’s abil-
