Introduction
   The SmartFusion® family of cSoCs builds on the technology first introduced with the Fusion mixed signal FPGAs. SmartFusion cSoCs are made possible by integrating FPGA technology with programmable high-performance analog and hardened ARM Cortex-M3 microcontroller blocks on a flash semiconductor process. The SmartFusion cSoC takes its name from the fact that these three discrete technologies are integrated on a single chip, enabling the lowest cost of ownership and smallest footprint solution to you.

General Description
Microcontroller Subsystem (MSS)
   The MSS is composed of a 100 MHz Cortex-M3 processor and integrated peripherals, which are interconnected via a multi-layer AHB bus matrix (ABM). This matrix allows the Cortex-M3 processor, FPGA fabric master, Ethernet message authentication controller (MAC), when available, and peripheral DMA (PDMA) controller to act as masters to the integrated peripherals, FPGA fabric, embedded nonvolatile memory (eNVM), embedded synchronous RAM (eSRAM), external memory controller (EMC), and analog compute engine (ACE) blocks.

   SmartFusion cSoCs of different densities offer various sets of integrated peripherals. Available peripherals include SPI, I2C, and UART serial ports, embedded FlashROM (EFROM), 10/100 Ethernet MAC, timers, phase-locked loops (PLLs), oscillators, real-time counters (RTC), and peripheral DMA controller (PDMA).
