The next step up in the Freescale PowerPC product line is PowerQUICC II. PQ II incorporates the company's G2 PowerPC core derived from the 603e embedded PowerPC core. These integrated communications processors operate at 133-450MHz and feature multiple 10/100Mbps Ethernet interfaces, security engines, and ATM and PCI support, among many others. The PQ II encompasses the MPC82xx products.
PQ II adds two new types of controllers to the QUICC engine. The FCC is a full-duplex fast serial communications controller. The FCC supports high-speed communications such as 100Mbps Ethernet and T3/E3 up to 45Mbps. The MCC is a multichannel controller capable of 128KB x 64KB channelized data.
Table 3-4 summarizes the highlights of selected PowerQUICC II processors.

Based on the Freescale PowerPC e300 core (evolved from the G2/603e), the PowerQUICC II Pro family operates at 266-667MHz and features support for Gigabit Ethernet, dual data rate (DDR) SDRAM controllers, PCI, high-speed USB, security acceleration, and more. These are the MPC83xx family of processors. The PQ II and PQ II Pro families of processors have been designed into a wide variety of equipment, such as LAN and WAN switches, hubs and gateways, PBX systems, and many other systems with similar complexity and performance requirements.
The PowerQUICC II Pro contains three family members without the QUICC engine, and two that are based on an updated version of the QUICC engine. The MPC8358E and MPC8360E both add a new Universal Communications Controller, which supports a variety of protocols.
Table 3-5 summarizes the highlights of select members of the PQ II Pro family.
