Actel SmartFusion混合信号FPGA开发评估方案

Actel公司的SmartFusion是集成了FPGA, ARM Cortex-M3和可编程模拟的智能混合信号FPGA,非常适合硬件和嵌入系统设计.本文介绍了SmartFusion混合信号FPGA主要特性,方框图, 以及SmartFusion评估板主要特性,部分电路图和马达控制与工业自动化的开发方框图.

Actel’s SmartFusion Intelligent Mixed-Signal FPGAs are the only devices that integrate an FPGA, ARM® Cortex™-M3, and programmable analog, offering full customization, IP protection, and ease-of-use. Based on Actels proprietary flash process, SmartFusion 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.

SmartFusion主要特性:

Microcontroller Subsystem (MSS)

• Hard 100 MHz 32-Bit ARM® Cortex™-M3

– 1.25 DMIPS/MHz Throughput from Zero Wait State Memory

Memory Protection Unit (MPU)

– Single Cycle Multiplication, Hardware Divide

– JTAG Debug (4 wires), Serial Wire Debug (SWD, 2 wires), and Single Wire Viewer (SWV) Interfaces

• Internal Memory

– Embedded Nonvolatile Flash Memory (eNVM), 64 Kbytes to 512 Kbytes
