TSPC860 General Description
The TSPC860 PowerPC QUad Integrated Communication Controller (Power QUICC®) is a versatile one-chip integrated microprocessor and peripheral combination that can be used in a variety of controller applications. It particularly excels in communications and networking systems. The Power QUICC (pronounced "quick") can be described as a PowerPC-based derivative of the TS68EN360 (QUICC™).
The CPU on the TSPC860 is a 32-bit PowerPC implementation that incorporates memory management units (MMUs) and instruction and data caches. The communications processor module (CPM) of the TS68EN360 QUICC has been enhanced with the addition of a Two-wire Interface (TWI) compatible with protocols such as I2C. Moderate to high digital signal processing (DSP) functionality has been added to the CPM. The memory controller has been enhanced, enabling the TSPC860 to support any type of memory, including high performance memories and newer dynamic random access memories (DRAMs). Overall system functionality is completed with the addition of a PCMCIA socket controller supporting up to two sockets and a real-time clock.
