PRODUCT DESCRIPTION
The SST49LF00xC flash memory devices are designed to
interface with host controllers (chipsets) that support a low-
pin-count (LPC) interface for system firmware applications.
The SST49LF00xC device complies with Intelâs LPC Inter-
face Specification 1.1, supporting a Burst-Read (up to 128
bytes in a single operation) which enables a 15.6 MByte
per second data transfer. 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.
The SST49LF00xC use a 5-signal LPC interface to support
both in-system and rapid factory programming using pro-
grammer equipment. A high voltage pin (WP#/AAI) is used
to enable Auto Address Increment (AAI) mode. The
SST49LF00xC offers hardware block protection in addition
to individual block protection via software registers for criti-
cal 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 as well as 12-KByte
Protected Data Area (PDA) enhances the userâs ability to
implement new security techniques and data protection
