MPC857TVR80B

The MPC857TVR80B is a single-core, 32-bit microprocessor in the MPC857 family, implementing the MPC8xx PowerPC architecture at an 80 MHz core frequency. Designed for embedded controller and communications applications, it integrates on-chip peripherals and communications support to simplify system design for consumer-grade networking and control products.

This device combines a PowerPC-based core with memory management and communications co-processing to deliver a compact, integrated solution for embedded networking and controller use cases where a 3.3 V I/O and surface-mount 357-PBGA (25×25) package are required.

Key Features

• Core  Embedded single-issue, 32-bit MPC8xx core implementing the PowerPC architecture, running at 80 MHz.
• Memory and MMU  Includes on-chip caches and memory-management features from the MPC8xx family; MPC857T-class devices use 4 KB instruction and 4 KB data caches and an MMU with a 32-entry TLB for virtual memory support.
• Communications Co-processor (CPM)  Integrated communications co-processor (CPM) for handling communications tasks and serial protocol processing.
• Ethernet  Dual Ethernet support: one 10 Mbps interface and one 10/100 Mbps interface for flexible network connectivity options.
• Interfaces  Additional interface support including HDLC/SDLC for serial link protocols and CPM-based communications peripherals.
• RAM Controller  Built-in DRAM controller to manage external memory interfacing.
• Supply and Mounting  3.3 V I/O voltage and surface-mount 357-PBGA (25×25) package for PCB assembly.
• Operating Range  Rated for operation from 0 °C to 105 °C, suitable for consumer electronics thermal environments.
• Regulatory  RoHS compliant, meeting standard environmental requirements for lead-free assembly.
• Qualification  Consumer-qualified device appropriate for consumer and similar embedded product markets.

Typical Applications

• Consumer Networking Equipment  Used in home and small-office routers, gateways, or access devices where dual Ethernet ports and on-chip communications support are required.
• Embedded Communications Systems  Suitable for embedded controllers that handle protocol processing and serial link interfaces (HDLC/SDLC) with CPM assistance.
• Controller Applications  Applicable to general-purpose embedded controller designs that require a 32-bit PowerPC architecture with DRAM interfacing and memory-management features.

Unique Advantages

• Integrated Communication Processing: On-chip Communications Processor Module (CPM) reduces external logic and offloads serial and protocol tasks from the CPU.
• Dual Ethernet Connectivity: One 10 Mbps and one 10/100 Mbps Ethernet interface provide flexible network options without additional controllers.
• Compact Surface-Mount Package: 357-PBGA (25×25) package enables high-density board layouts for space-constrained embedded designs.
• PowerPC Architecture with MMU: MPC8xx core with MMU and TLB support facilitates operating-system-level memory management and robust software architectures.
• Ready for Consumer Products: Consumer qualification and RoHS compliance align the device with lead-free manufacturing and consumer market requirements.
