• Ethernet Connectivity  Multiple 10/100 Mbps Ethernet interfaces for networked embedded systems and communications equipment.
• Peripheral Interfaces  Includes I2C and other serial interfaces for system management and peripheral control.
• Package & Mounting  480-LBGA exposed pad, supplier device package 480-TBGA (37.5×37.5); surface-mount mounting type suited for compact board designs.
• Power & Voltage  I/O voltage specified at 3.3 V with separate supply domains described in family documentation for core and I/O power management.
• Reliability & Qualification  Industrial qualification and RoHS compliance for deployment in industrial environments.
• Operating Range  Rated for operating temperatures from −40 °C to 105 °C for extended-temperature applications.
• Architectural Enhancements (Family)  Members of the MPC826xA family include features such as separate 16 KB instruction and data caches, floating-point support, and separate PLLs for core and communications subsystems (as documented in family specifications).

Typical Applications

• Industrial Control Systems  Deterministic single-core processing and industrial temperature qualification suit control, monitoring, and automation platforms.
• Embedded Communications Equipment  On-chip communications co-processors and multiple 10/100 Mbps Ethernet interfaces enable use in switches, gateways, and protocol-handling modules.
• Networking Appliances  Integrated memory controllers and CPM offload capabilities support compact networked devices requiring external DRAM/SDRAM.
• Protocol and Serial I/O Offload  RISC CPM and serial interfaces are well matched for designs that require dedicated protocol handling and serial peripheral control.

Unique Advantages

• Integrated Communications Acceleration: The inclusion of communications co-processors and a CPM reduces CPU overhead for protocol processing and serial I/O tasks.
• Industrial-Grade Operation: Qualification for −40 °C to 105 °C operation and RoHS compliance support deployment in demanding embedded environments.
• Compact, Manufacturable Package: The 480-TBGA (37.5×37.5) exposed-pad package enables high-density surface-mount assembly while providing thermal path for board-level cooling.
• Memory Flexibility: On-chip DRAM/SDRAM controllers allow designers to choose suitable external memory configurations for application performance and capacity needs.
• Network-Ready I/O: Multiple 10/100 Mbps Ethernet ports and I2C simplify integration into networked and managed systems.
