XC6SLX45T-2FGG484C Xilinx AMD Spartan-6 FPGA
XC6SLX45T-2FGG484C 是 Xilinx Spartan-6 家族中一款在成本与性能之间取得良好平衡的中高密度 FPGA，面向批量化的嵌入式、工业与消费类产品。它基于成熟的 45 nm 工艺，器件资源能满足常见的并行逻辑、定点 DSP 和中等规模存储需求：器件大约包含 43,661 个逻辑单元（logic cells），片上 Block RAM 总量约为 2,088 Kb（以 18 Kb 为单位的 BRAM 组块），内置约 58 个 DSP48A1 乘加切片（适合 18×18 位定点乘法累加），并在 FGG484 封装下提供接近 300 个用户 I/O（实际可用 I/O 受封装映射与 VCCO 配置影响）
Spartan-6 把可配置逻辑单元（CLB/LAB）、片上 RAM、DSP 切片、专用时钟模块（CMT，包含 PLL/DCM）和多种 I/O 单元结合在一起，形成一个适合做数据前端、协议处理与低至中速并行计算的系统级可编程平台。DSP48A1 的存在使得该器件在定点滤波、FIR/IIR、FFT 前端、音视频预处理和其他乘加密集型应用中表现优越；Block RAM 则便于实现本地 FIFO、缓存或状态保存，减轻外部内存带宽压力。器件支持丰富的 I/O 标准，包括 LVCMOS、电平兼容标准、差分 LVDS 以及适用于存储器接口的 SSTL/HSTL 等，能与多种外设和外部存储器类型对接。
FGG484 封装为板级设计提供了较多的 I/O 引脚布局灵活性，可实现多种总线与高速链路（例如 LVDS 差分链路、多个并行接口或差分串行线路）。器件支持常见的配置/编程方式：JTAG、从 SPI/Flash 加载的 Slave Serial 或从片外并行 PROM（SelectMAP/BPI）配置等，便于在量产时采用外部闪存储存 bitstream 并通过主控序列完成上电加载。
同时需要注意的局限性：与更新的 FPGA 家族相比（例如 7 系列、UltraScale），Spartan-6 在逻辑密度、片上内存带宽、DSP 密度与高速 SerDes 能力（速率与通道数）上都有限制，因此对于需要极高带宽、超大规模并行或需要 HBM/大量 SerDes 的应用并不适合。
