PRODUCT DESCRIPTION
The SST49LF016C flash memory device is designed to
interface with host controllers (chipsets) that support a low-
pin-count (LPC) interface for system firmware applications.
Complying with LPC Interface Specification 1.1,
SST49LF016C supports a Burst-Read data transfer of
15.6 MBytes per second at 33 MHz clock speed and 31.2
MBytes per second at 66 MHz clock speed, up to 128
bytes in a single operation.
The LPC interface operates with 5 signal pins versus 28
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 simplified signal
routing. This 5-signal LPC interface supports both in-sys-
tem and rapid factory programming using programmer
equipment. A high voltage pin (WP#/AAI) enables Auto
Address Increment (AAI) mode.
Via the software registers, the SST49LF016C offers hard-
ware block protection and individual block protection for crit-
ical system code and data. The 256-bit Security ID space is
comprised of a 64-bit factory pre-programmed unique
number and a 192-bit One-Time-Programmable (OTP)
area. This Security ID permits the use of new security tech-
niques and implementation of a new data protection
scheme. To protect against inadvertent write, the
SST49LF016C device has on-chip hardware and software
write protection schemes. The SST49LF016C also pro-
vides general purpose inputs (GPI) for system design flexi-
bility.
Manufactured with SST proprietary, high-performance
SuperFlash technology, SST49LF016C has a split-gate cell
design and thick-oxide tunneling injector for greater reliabil-
ity and manufacturability compared with alternative technol-
ogy approaches.
