PowerQUICC is the name for several Power Architecture based microcontrollers from Freescale Semiconductor. They are built around one or more PowerPC cores and the Communications Processor Module ( QUICC Engine) which is a separate RISC core specialized in such tasks such as I/O, communications, ATM, security acceleration, networking and USB. Many components are System-on-a-chip designs tailor made for embedded applications.
PowerQUICC processors are used in networking, automotive, industrial, storage, printing and consumer applications. Freescale are using PowerQUICC processors as a part of their mobileGT platform.
Freescale also manufactures QUICC microcontrollers based on the older 68k technology.
There are four distinct lines of processors, mainly based on processing power.
