• Communications Processor (CPM) Integrated RISC communications processor for offloading protocol processing and handling communications tasks.
• Ethernet Integrated 10/100-Mbps Fast Ethernet controller with large on-chip FIFOs and bursting DMA; supports 10-Mbps interfaces as well. Full-duplex 100-Mbps operation is supported at the 50 MHz system clock rate.
• Protocol Support Built-in support for HDLC/SDLC and multichannel protocol processing (QMC), with ATM support noted in the series documentation.
• Memory and Buffers DRAM controller support and on-chip buffer/FIFO structures for Ethernet and communications use; series devices include an 8-KByte dual-port RAM when available.
• Power and IO 3.3 V I/O voltage for common embedded system compatibility.
• Package and Mounting 357-PBGA (25×25) / 357-BBGA package, surface-mount mounting for compact embedded board designs.
• Operating Range & Qualification Industrial-grade qualification with operating temperature range −40 °C to 95 °C.
• Compliance RoHS compliant.
• Graphics Acceleration No graphics acceleration; device focuses on communications and protocol processing functions.

Typical Applications

• SOHO and Small Router Platforms Integrated Ethernet MAC and CPM make the MPC855TCVR50D4 suitable for consumer and small-office routing appliances requiring onboard protocol handling.
• ADSL and Cable Modems Targeted for low-cost modem and gateway designs where integrated communications processing and Ethernet connectivity reduce external component count.
• Telecommunications Systems Support for multichannel protocols, HDLC and ATM in the MPC8xx family enables use in telecom line cards and channelized protocol processors.
• Embedded Networking Controllers General-purpose embedded networking controllers that require combined CPU and communications acceleration benefit from the device’s integrated CPM and Ethernet features.

Unique Advantages

• Integrated Communications Subsystem: Combines a high-performance MPC8xx core with an embedded CPM to offload protocol processing and reduce system-level complexity.
