MPC8255ACZUMIBB

The MPC8255ACZUMIBB is a PowerPC G2 single-core microprocessor operating at 266 MHz in a 480-TBGA (37.5 × 37.5 mm) package. It is designed for embedded and communications-focused systems where integrated communications processing, memory interface flexibility, and extended temperature operation are required.

With an on-chip communications processor module (RISC CPM), DRAM/SDRAM controllers, and 10/100 Mbps Ethernet support, this industrial-qualified device targets industrial and embedded applications that need deterministic processing, multi-protocol interfacing, and package-level robustness.

Key Features

• Core  PowerPC G2 32-bit single core running at 266 MHz, providing deterministic instruction throughput for embedded control and communications tasks.
• Memory and Cache  On-chip support for DRAM and SDRAM controllers; the G2 core architecture includes separate instruction and data caches as described in the device family documentation.
• Communications Processor Module (CPM)  Integrated RISC CPM for communications offload and protocol handling to simplify system design and reduce host core load.
• Ethernet Connectivity  10/100 Mbps Ethernet support, enabling standard LAN connectivity for embedded networking and industrial control.
• Serial and System Interfaces  Additional interfaces include I2C and other serial/peripheral interfaces provided by the device family to support system management and peripheral control.
• Power and Clocking  3.3 V I/O voltage specification. Family-level features include separate power domains and clocking elements to allow optimization of core and peripheral clocking.
• Package and Mounting  480-LBGA exposed-pad package (480-TBGA, 37.5 × 37.5 mm) for surface-mount assembly and thermal handling on industrial PCBs.
• Temperature and Qualification  Industrial qualification with operating temperature range of −40 °C to 105 °C for use in harsh environments.
• Regulatory  RoHS compliant.

Typical Applications

• Industrial Networking: Use as a communications processor for industrial Ethernet endpoints and protocol gateways where 10/100 Mbps connectivity and CPM offload are required.
• Embedded Control Systems: Deploy in control nodes requiring deterministic 32-bit processing at 266 MHz and DRAM/SDRAM support for application memory.
• Telecommunications Equipment: Integrate into line-card or edge devices that need on-chip CPM resources and serial interfaces for packet handling and protocol processing.
• Ruggedized Devices: Suitable for systems operating across −40 °C to 105 °C that require surface-mount mounting and a thermally managed exposed-pad BGA package.

Unique Advantages

• Integrated Communications Offload: On-chip RISC CPM reduces host core burden for protocol handling and serial DMA tasks, simplifying firmware partitioning.
• Memory Interface Flexibility: Built-in DRAM and SDRAM controllers let designers choose common external memory types without separate controller ICs.
• Industrial Temperature Range: Rated from −40 °C to 105 °C to support deployment in demanding environmental conditions.
• Robust Packaging: 480-TBGA with exposed pad supports thermal dissipation and reliable surface-mount assembly for industrial PCBs.
• Standards-Oriented Connectivity: 10/100 Mbps Ethernet and I2C support enable straightforward integration into networked and sensor-driven systems.
