描述 Description

MPC866 PowerQUICC? Family is a 0.18 micron version of the MPC862 PowerQUICC? Family and can operate up to 133 MHz on the MPC8xx core with a 66 MHz external bus. The MPC866 Family has a 1.8 V core and has a 3.3 V I/O operation with 5 V TTL compatibilty. The MPC866 Integrated Communications Controller Family is a versatile one-chip integrated microprocessor and peripheral combination that can be used in a variety of controller applications. It particularly excels in both communications and networking systems.
The MPC866 Family is a a Power Architecture-based derivative of Our Quad Integrated Communications Controller (PowerQUICC). The CPU on the MPC866 is the MPC8xx core, a 32-bit microprocessor built on Power Architecture technology, incorporating memory management units (MMUs) and instruction and data caches. The MPC866P is the superset of this family of devices.

特性 Features

Embedded MPC8xx core up to 133 MHz
? Maximum frequency operation of the external bus is 66 MHz
? Single-issue, 32-bit core (compatible with Power Architecture technology)with 32, 32-bit general-purpose registers (GPRs)
? The MPC866 Family provides enhanced ATM functionality as found on the MPC862.The MPC866 adds major new features available in \"enhanced SAR\" (ESAR) mode,including the following:
? Improved operation, administration and maintenance (OAM) support
? OAM performance monitoring (PM) support
? Multiple APC priority levels available to support a range of trafficpace requirements
? Port-to-port switching capability without the need for RAM-based microcode
? Simultaneous MII (100Base-T) and UTOPIA (half-duplex) capability
? Optional statistical cell counters per PHY
? UTOPIA level 2 compliant interface with added FIFO buffering to reducethe total cell transmission time. (The earlier UTOPIA level 1 specificationis also supported.)
? Parameter RAM for both SPI and I2C can be relocated without RAM-basedmicrocode
? Supports full-duplex UTOPIA both master (ATM side) and slave (PHY side)operation using a \"split\" bus

? Two SMCs (serial management channels)
? One SPI (serial peripheral interface)
? One I2C (inter-integrated circuit) port
? Time-slot assigner (TSA)
? Parallel interface port (PIP)
? PCMCIA interface
? Debug interface
? 1.8 V Core and 3.3 V I/O operation with 5-V TTL compatibility
? 357-pin ball grid array (BGA) package
