MPC8260AZUMHBB

The MPC8260AZUMHBB is a PowerPC G2 microprocessor single-core device operating at 266 MHz, designed for embedded applications that require integrated communications and system-level peripherals. It belongs to the MPC82xx family and provides a combination of core performance and on-chip communications functionality geared toward networking and embedded control use cases.

Key value is delivered through a 32-bit PowerPC G2 core, integrated communications co-processor (CPM), memory controllers for DRAM/SDRAM, and a high-density 480-TBGA package, enabling compact, high-pin-count system designs with support for Ethernet and standard serial interfaces.

Key Features

• Core  PowerPC G2 single-core 32-bit processor running at 266 MHz.
• Memory  On-chip controllers for DRAM and SDRAM to support system memory requirements.
• Communications Co-processor  Integrated Communications Processor Module (RISC CPM) for communications offload and serial DMA support.
• Ethernet  10/100Mbps Ethernet capability (specification lists "10/100Mbps (3)").
• Serial and Control Interfaces  Additional interfaces include I2C along with multiple serial controllers available via the CPM.
• Packaging  480-LBGA exposed pad, supplied in a 480-TBGA package with 37.5×37.5 mm body — designed for surface-mount assembly.
• Power and Clocking  3.3 V I/O voltage and on-chip clocking architecture described in the MPC8260A PowerQUICC II documentation, including separate PLLs for core and CPM and selectable clock multipliers.
• Memory Management and Acceleration  Family-level documentation references separate 16-Kbyte instruction and data caches and an MMU in the G2 core.
• Operating Range & Compliance  Operating temperature 0 °C to 105 °C and RoHS compliant; qualification level listed as Consumer.

Typical Applications

• Embedded Networking Equipment  Use for packet handling and control in embedded routers, switches, and gateways leveraging on-chip CPM and 10/100Mbps Ethernet.
• Communications Controllers  Offload and manage serial and time-division multiplexing tasks using the integrated CPM and serial DMA resources.
• Industrial Control Systems  Embedded control and supervisory applications benefiting from the 266 MHz PowerPC G2 core, DRAM/SDRAM support, and extended temperature up to 105 °C.
• General Embedded Processing  Platform processing for consumer and embedded products requiring a high-pin-count TBGA package and diverse I/O.

Unique Advantages

• Highly integrated communications support: The on-chip RISC CPM and serial DMA reduce external components for communications-centric designs.
• Flexible memory interface: Native DRAM and SDRAM controllers simplify memory subsystem design and speed time to market.
• High I/O density package: 480-TBGA (37.5×37.5 mm) package with exposed pad accommodates extensive external connectivity and thermal management.
• Configurable clock and power domains: Separate PLLs and clock multiplier options (documented for the MPC8260A family) enable frequency and power optimization across core and CPM domains.
• RoHS compliant with extended operating range: Environmentally compliant construction and an operating temperature up to 105 °C support a range of consumer and industrial embedded applications.
