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.
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-
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

Advance Information
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 technolo-
gies. The SuperFlash technology provides fixed Erase and
Program time, independent of the number of Erase/Pro-
gram cycles that have performed. Therefore the system
software or hardware does not have to be calibrated or cor-
related to the cumulative number of erase cycles as is nec-
essary with alternative flash memory technologies, whose
Erase and Program time increase with accumulated Erase/
Program cycles. To protect against inadvertent write, the
SST49LF016C device has on-chip hardware and software
write protection schemes. It is offered with a typical endur-
ance of 100,000 cycles. Data retention is rated at greater
than 100 years.
The SST49LF016C product provides a maximum program
time of 10 µs per byte with a single-byte Program opera-
tion; effectively 5 µs per byte with a dual-byte Program
operation and 2.5 µs per byte with a quad-byte Program
operation. End-of-Write can be detected by the RY/BY# pin
output in AAI mode and by reading the software status reg-
ister during an in-system Program or Erase operation.
The SST49LF016C is offered in 32-lead PLCC, 32-lead
TSOP and 40-lead TSOP packages. In addition, SST is
,
providing lead-free (non-Pb) package options to address the
growing need for non-Pb solutions in electronic compo-
nents. Non-Pb package version can be obtained by ordering
products with a package code suffix of “E” as the environ-
mental attribute in the product part number. See Figures 2,
3, and 4 for pin assignments and Table 1 for pin descriptions.
