MPC855TVR80D4

The MPC855TVR80D4 is a single-core, 32-bit MPC8xx microprocessor operating at 80 MHz with 3.3 V I/O, supplied in a 357‑pin PBGA (25×25) surface-mount package. It integrates a high-performance MPC8xx core, a Communications Processor Module (CPM), and an on‑chip 10/100 Mbps Ethernet controller to address cost‑sensitive networking and communications controller applications.

Designed for consumer-qualified networking products, the MPC855T family is targeted at SOHO routers, ADSL and cable modem designs, and similar telecommunications and networking systems that benefit from on‑chip communications acceleration and Ethernet connectivity.

Key Features

• Core and Performance 1 core, 32‑bit MPC8xx core running at 80 MHz for general-purpose application processing.
• Communications Processor Module (CPM) Integrated CPM provides a RISC communications processor for protocol processing and co‑processor functions.
• Integrated Ethernet Controller On‑chip 10/100 Mbps Fast Ethernet controller with large transmit/receive FIFOs and bursting DMA for high‑performance Ethernet connectivity; device also supports a 10 Mbps channel.
• Protocol Support CPM‑based support for communications protocols including HDLC/SDLC and ATM as described for the MPC8xx family, enabling multichannel protocol processing and offload.
• Memory and DMA Supports external DRAM controllers and off‑chip buffer descriptor rings for flexible management of transmit and receive buffer memory; includes on‑chip dual port RAM in the MPC8xx family context.
• Interfaces Multiple Ethernet physical interface options supported by the MAC (including MII and 7‑wire 10 Mbps), plus HDLC/SDLC for serial protocol framing.
• Power and I/O 3.3 V I/O voltage for compatibility with common networking peripheral levels.
• Package and Mounting 357‑pin PBGA (25×25) surface‑mount package for compact board implementation.
• Operating Conditions and Compliance Consumer qualification with an operating temperature range of 0 °C to 95 °C and RoHS compliance.

Typical Applications

• SOHO Routers Integrated Ethernet MAC and CPM offload capabilities make the device suitable for home and small‑office routing platforms.
• ADSL and Cable Modems On‑chip communications processing and 10/100 Mbps Ethernet support are well matched to broadband modem front‑end designs.
• Telecommunications Systems CPM support for HDLC, ATM and multichannel protocol processing provides protocol handling useful in cost‑sensitive telecom equipment.
• General Purpose Networking Controllers The combined MPC8xx core, CPM and Ethernet controller enable compact, integrated controller designs for networking applications.

Unique Advantages

• Highly integrated solution: Combines an MPC8xx application core, CPM communications processor and a 10/100 Mbps Ethernet controller on one chip to reduce component count and simplify board design.
• Built‑in communications offload: CPM provides dedicated protocol processing (HDLC/SDLC, ATM) to offload networking tasks from the main CPU, enabling efficient packet handling.
• Flexible Ethernet connectivity: Fast Ethernet MAC with large FIFOs and DMA plus multiple physical interface options supports varied link requirements and external PHY choices.
• Consumer‑grade operating range: Qualified for consumer applications with an operating temperature range of 0 °C to 95 °C and RoHS compliance for regulatory alignment.
• Compact package: 357‑pin PBGA (25×25) surface‑mount package provides high pin density for integrated I/O in space‑constrained designs.
