Lattice iCE40 HX超低功耗mobileFPGA系列开发方案

Lattice公司的iCE40 HX超低功耗mobileFPGA系列,和其它任何的CPLD或FPGA器件相比,可提供最低的静态和动态功耗,大约640到7680个逻辑单元和触发器,每个器件包含8到32个RAM区块,每个区块有4Kb存储,用于数据存储和缓冲,特别适合对成本敏感和量大的应用.本文介绍了iCE40 HX系列主要特性,iCE40 HX系列架构图,主要产品和特性,以及iCEblink40 iCE40HX1K 评估板主要特性,电路图,主要元件清单和PCB元件布局图.

The Lattice Semiconductor iCE40 LP-Series and HX-Series programmable logic family are designed to deliver the lowest static and dynamic power consumption of any comparable CPLD or FPGA device. iCE40 FPGAs are designed specifically for cost-sensitive, high-volume applications. iCE40 FPGA are fully user-programmable and can self-configure from a configuration image stored in on-chip, nonvolatile configuration memory (NVCM) or stored in an external commodity SPI serial Flash PROM or downloaded from an external processor over an SPI-like serial port. iCE40 components deliver from approximately 640 to 7,680 logic cells and flip-flops while consuming a fraction of the power of comparable programmable logic devices. Each iCE40 device includes 8 to 32 RAM blocks, each with 4Kbits storage, for on-chip data storage and data buffering.

Each iCE40 device consists of five primary architectural elements.
