PowerQUICC® Processor with CPM (1 SCC, 2 SMC), 10/100 Ethernet

Overview

Archived content is no longer updated and is made available for historical reference only.

The MPC857T PowerQUICC™ Integrated Communications Processor is a versatile one-chip integrated microprocesor and peripheral combination that can be used in a variety of controller applications. It particularly excels in both communications and networking systems.

The MPC857T is a Power Architecture-based derivative of NXP^® Semiconductors's MPC860 PowerQUICC™ Integrated Communications Processor. The embedded CPU on the MPC859T is a 32-bit processor (the MPC8xx core) built on Power Architecture technology that incorporates memory management units (MMUs) and instruction and data caches. The communications processor module (CPM) from the MPC860 PowerQUICC^® has been enhanced by the addition of the inter-integrated controller (I²C) channel. The memory controller has been enhanced, enabling the MPC857T to support any type of memory, including high-performance memories and new types of DRAMs. A PCMCIA socket controller supports up to two sockets. A real-time clock has also been integrated.

Features

The following list summarizes the key MPC857T features:

Embedded MPC8xx core
Single-issue, 32-bit version of the core (compatible with the Power Architecture definition) with 32, 32-bit general-purpose registers (GPRs)
The MPC857T provides enhanced ATM functionality over that of the MPC860SAR. The MPC857T adds major new features available in "enhanced SAR" (ESAR) mode, including the following:
- Multiple APC priority levels available to support a range of traffic pace requirements
- Port-to-port switching capability without the need for RAM-based microcode
- Simultaneous MII (100Base-T) and UTOPIA (half-duplex) capability
- Parameter RAM for both SPI and I²C can be relocated without RAM-based microcode
- Supports full-duplex UTOPIA leader (ATM side) operation using a "split" bus
Up to 32-bit data bus (dynamic bus sizing for 8, 16, and 32 bits)
32 address lines
Complete static design
Memory controller (eight banks)
General-purpose timers
Fast Ethernet controller (FEC)
System integration unit (SIU)
Interrupts
Communications processor module (CPM)
Four baud rate generators
One SCC (serial communication controller)
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
Low power support
Debug interface
3.3 V operation
357-pin ball grid array (BGA) package
