The MPC8xx series PowerQUICC Processor with CPM (2 SCC, 1 SMC) and 10/100Mbps Ethernet. The MPC852T is a 0.18-micron derivative of the MPC860 PowerQUICC™ family and can operate up to 100MHz on the MPC8xx core with a 66MHz external bus. The MPC852T has a 1.8V core and a 3.3V I/O operation with 5V TTL compatibility. The MPC852T integrated communications controller is a versatile one-chip integrated microprocessor and peripheral combination that can be used in a variety of controller applications. It particularly excels in Ethernet control applications, including CPE equipment, Ethernet routers and hubs, VoIP clients and Wi-Fi access points. The MPC852T is a PowerPC architecture-based derivative of the MPC860 quad integrated communications controller (PowerQUICC). The CPU on the MPC852T is a MPC8xx core, a 32-bit microprocessor that implements the PowerPC architecture, incorporating memory management units (MMUs) and instruction and data caches.
