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.
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-
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.

Advance Information
The total energy consumed is a function of the applied volt-
age, current and time of application. Since for any given
voltage range, the SuperFlash technology uses less cur-
rent 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 SuperFlash technology provides fixed Erase and Pro-
gram time, independent of the number of Erase/Program
cycles that have performed. 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 protect against inadvertent write, the
SST49LF160C device has on-chip hardware and software
write protection schemes. It is offered with a typical endur-
16 Mbit LPC Flash
SST49LF160C
ance of 100,000 cycles. Data retention is rated at greater
than 100 years.
The SST49LF160C 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 SST49LF160C is offered in a 32-PLCC lead-free
package to address the growing need for non-Pb solutions
in electronic components. Non-Pb package versions can
be obtained by ordering products with a package code suf-
fix of “E” as the environmental attribute in the product part
number. See Figure 3 for pin assignments and Table 1 for
pin descriptions.
