Analog Devices BF518F FMC Development Kit The ADSP-BF512/ADSP-BF512F, ADSP-BF514/ADSPBF514F, ADSP-BF516/ADSP-BF516F, ADSP-BF518/ADSPBF518F processors are members of the Blackfin® family of products, incorporating the Analog Devices/Intel Micro Signal Architecture (MSA). Blackfin processors combine a dual-MAC state-of-the-art signal processing engine, the advantages of a clean, orthogonal RISC-like microprocessor instruction set, and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture. The processors are completely code compatible with other Blackfin processors. BF51xF主要特性: Up to 400MHz high performance Blackfin processor Two 16-bit MACs, two 40-bit ALUs, four 8-bit video ALUs, 40-bit shifter RISC-like register and instruction model for ease of programming and compiler-friendly support Advanced debug, trace, and performance monitoring Wide range of operating voltages Qualified for Automotive Applications 168-ball CSP_BGA or 176-lead LQFP with exposed pad MEMORY 116K bytes of on-chip memory External memory controller with glueless support for SDRAM and asynchronous 8-bit and 16-bit memories Optional 4M bit SPI flash with boot option Flexible booting options from internal SPI flash, OTP memory, external SPI/parallel memories, or from SPI/UART host devices Code security with Lockbox secure technology One-time-programmable (OTP) memory Memory management unit providing memory protection PERIPHERALS IEEE 802.3-compliant 10/100 Ethernet MAC with IEEE 1588 support (ADSP-BF518/ADSP-BF518F only) Parallel peripheral interface (PPI), supporting ITU-R 656 video data formats 2 dual-channel, full-duplex synchronous serial ports (SPORTs), supporting 8 stereo I2S channels 12 peripheral DMAs, 2 mastered by the Ethernet MAC 2 memory-to-memory DMAs with external request lines Event handler with 56 interrupt inputs 2 serial peripheral interfaces (SPI) Removable storage interface (RSI) controller for MMC, SD, SDIO, and CE-ATA 2 UARTs with IrDA support 2-wire interface (TWI) controller Eight 32-bit timers/counters with PWM support 3-phase 16-bit center-based PWM unit 32-bit general-purpose counter Real-time clock (RTC) and watchdog timer 32-bit core timer 40 general-purpose I/Os (GPIOs) Debug/JTAG interface On-chip PLL capable of frequency multiplication

圖2.BF51xF Blackfin處理器核框圖 BF518F FMC CPU Evaluation Kit provides a complete development platform for designing and verifying applications based on the Analog Devices Blackfin BF51xF family of DSP processors. The kit enables designers to use the BF518F controller with on board standard peripherals and expand their prototype system by enabling customization through the FMC LPC expansion slot. The Analog Devices BF518F FMC Development Kit, designed by and available exclusively from Avnet Electronics Marketing, provides a simple-to-use platform for hardware and software engineers designing with the Analog Devices BF518F low-power Blackfin® processor and the Microsoft .NET Micro Framework. The board can operate either as a standalone, or as an FMC Mezzanine Module connected to any VITA 57.1-compliant carrier board. By providing a convenient development platform for applications that combine FPGAs and embedded processors with advanced networking capability, it has never been easier to include signal processing in your next design. 主要應用: Industrial automation HM Smart energy management Network-enabled instrumentation Test and measurement
