                  TI is M-Shield security technology includes secure read-only
                  memory (ROM), unique hardware-based public keys, and other
                  protection measures to safeguard valuable information, data
                  and software stored on a handset, including sensitive personal
                  information of handset owners as well as the device is boot
                  code and other critical firmware modules provided by the
                  handset manufacturer. The investment handset manufacturers
                  have made in developing software and other intellectual
                  property (IP) is protected against piracy and the handset
                  itself is safeguarded against malicious attackers attempting
                  to install viruses, worms and other unwanted software on the
                  device.

                  Fabricating the “LoCosto ULC” solutions with 65-nm process
                  technology as well as several other chip- and system-level
                  cost optimization techniques all contribute to the device is
                  sustainable ULC characteristics. For example, the electronic
                  bill of materials (eBOM) for an entry-level ULC handset is
                  reduced by up to 25 percent with the “LoCosto ULC” solutions
                  compared with the previous generation. Additionally,
                  fabricating the chip at a smaller process node means that the
                  chip itself is substantially smaller. This, along with
                  component reduction, reduces the size of a handset is PCB,
                  lowering the manufacturing cost of the cell phone. Integration
                  of the power management with the digital baseband into a
                  single chip also yields reduction in the modem PCB area.
