MPC857TVR100B

The MPC857TVR100B is a single-core, 32-bit microprocessor in the MPC8xx family implementing the PowerPC architecture. It integrates core processing, packet/communication offload and system I/O to address embedded controller, communications and networking applications.

Running at 100 MHz with 3.3 V I/O, the device combines on-chip communications processing (CPM), DRAM controller support and multiple Ethernet interfaces to simplify system design and deliver a compact, surface-mount solution in a 357‑pin PBGA (25×25) package.

Key Features

• Core & Architecture  Embedded single-issue, 32-bit MPC8xx core implementing the PowerPC architecture with branch prediction and standard PowerPC register/TLB structures as used across the MPC862/857T family.
• Memory & MMU  On-chip caches and MMU features from the MPC8xx family (including set-associative instruction/data caches and a 32-entry TLB) provide efficient code and data handling for embedded workloads.
• Communications Co-Processor (CPM)  Integrated CPM supports communications and DSP-style offload for packet processing and protocol handling.
• Ethernet Connectivity  Dual Ethernet capability including one 10 Mbps port and one 10/100 Mbps port to support mixed-speed network designs.
• System Interfaces  Built-in DRAM controller support and additional serial/protocol interfaces including HDLC/SDLC for common embedded communications protocols.
• Performance & Power  100 MHz core frequency with 3.3 V I/O operating voltage suitable for a range of embedded power envelopes.
• Package & Mounting  Surface-mount 357‑pin PBGA (25×25) package for compact board-level integration.
• Operating Range & Compliance  Qualified for consumer applications with an operating temperature range of 0 °C to 105 °C and RoHS compliance for environmental requirements.

Typical Applications

• Communications Equipment  Use the integrated CPM and Ethernet ports for protocol processing and medium-speed packet handling in routers, gateways and access equipment.
• Embedded Networking Appliances  Ideal for compact network appliances that require on-chip DRAM interface and mixed 10/100 Mbps Ethernet connectivity.
• Control and Automation Systems  Single-core 32-bit processing with serial protocol support (HDLC/SDLC) suits protocol translation, controller and protocol offload tasks in embedded controllers.
• Consumer Connectivity Devices  Consumer-grade qualification and RoHS compliance make it suitable for consumer networking and connectivity products requiring integrated communications features.

Unique Advantages

• Integrated Communications Subsystem: On-chip CPM and HDLC/SDLC interfaces reduce external components and simplify designs that need protocol handling and serial communications.
• Dual Ethernet Support: Built-in 10 Mbps and 10/100 Mbps Ethernet ports provide flexibility for mixed-speed network deployments without additional PHYs.
• PowerPC-Based MPC8xx Core: The established MPC8xx PowerPC architecture delivers predictable 32-bit processing behavior and MMU/cache features for embedded software stacks.
• Compact Surface-Mount Package: 357‑pin PBGA (25×25) enables high-density board layouts while preserving necessary I/O for system integration.
• Consumer Qualification & RoHS Compliance: Consumer-level qualification and RoHS compliance streamline use in consumer electronics and ensure regulatory conformity.
• Extended Operating Temperature: Rated 0 °C to 105 °C to support a range of deployment environments within consumer and industrial-adjacent products.
