KMPC8270VRMIBA

The KMPC8270VRMIBA is a PowerPC G2_LE microprocessor in the MPC8270 series, implemented as a single 32‑bit core running at 266 MHz and supplied in a 516‑PBGA (27x27) package. It targets embedded communications and networking applications where on‑chip peripheral integration and deterministic processing are required.

Designed as a member of the PowerQUICC II family of integrated communications processors, the device pairs a dual‑issue integer G2_LE core with on‑chip memory structures and dedicated communications co‑processing to simplify system design for consumer and embedded networking products.

Key Features

• Core  Dual‑issue integer PowerPC G2_LE core; single 32‑bit processor running at 266 MHz.
• On‑chip caches  Separate instruction and data caches (16 KB each as specified in family datasheet) to improve instruction throughput and data locality.
• Memory controllers  Integrated DRAM and SDRAM controllers for system memory interfacing.
• Communications co‑processors  Built‑in communications co‑processors including a RISC CPM for offloading protocol handling.
• Networking interfaces  Three 10/100 Mbps Ethernet controllers to support multi‑port networking applications.
• USB  One USB 2.0 full/low‑rate interface for peripheral connectivity.
• Additional interfaces  I2C interface available for board control and peripheral configuration.
• Package & mounting  516‑PBGA supplier device package (27x27) in a surface‑mount form factor.
• Electrical & environmental  3.3 V I/O voltage and RoHS compliant.
• Operating temperature  Specified for 0 °C to 105 °C operating range.

Typical Applications

• Embedded networking equipment  Multi‑port Ethernet connectivity and integrated protocol offload make it suitable for routers, switches, and gateways.
• Consumer communication devices  USB and Ethernet interfaces support consumer networking peripherals and home connectivity products.
• Industrial embedded controllers  On‑chip DRAM/SDRAM controllers and robust operating temperature range enable compact control and monitoring systems.

Unique Advantages

• Integrated communications peripherals: Multiple Ethernet ports, USB 2.0 and a RISC CPM reduce external component count and simplify board design.
• Balanced processing and memory: 266 MHz G2_LE core with separate 16 KB instruction and data caches delivers deterministic embedded performance for protocol processing.
• Standard 3.3 V I/O: 3.3 V compatibility eases interfacing with common peripheral devices and legacy bus logic.
• Compact PBGA package: 516‑PBGA (27x27) surface‑mount package supports high‑density board layouts.
• RoHS compliant: Meets current environmental compliance expectations for consumer and commercial products.
