SmartFusion

Overview

SmartFusion^® System on Chip (SoC) FPGAs are the only devices that integrate an FPGA fabric, ARM Cortex-M3 Processor, and programmable analog circuitry, offering the benefits of full customization and IP protection, while still being easy to use. Based on a proprietary flash process, SmartFusion SoC FPGAs are ideal for hardware and embedded designers who need a true system-on-chip (SoC) solution that gives more flexibility than traditional fixed-function microcontrollers without the excessive cost of soft processor cores on traditional FPGAs.
