The company is based in Austin, Texas, and has design, research and development, manufacturing or sales operations in more than 30 countries.

Their unparalleled portfolio of power management solutions, microprocessors, microcontrollers, sensors, radio frequency semiconductors, analog and mixed signal circuits and software technologies are embedded in products used around the world.

The MPC855T is a versatile one-chip integrated microprocessor and peripheral combination designed for lower cost access equipment that requires fast ethernet support capable of 100 Mbps. This member of the MPC860 PowerQUICC™ family combines an MPC8xx core processor along with Freescale Semiconductor's own Communication Processor Module, a separate RISC engine specifically designed to offload communication tasks from the MPC8xx core.

It differs from existing PowerQUICC family members in that the MPC855T features only one Serial Communications Controller instead of four. In addition, the MPC855T is manufactured in Freescale's 0.32µ process technology allowing for 3.3 volt core operation and 3.3 volt I/O.
