[原创] Lattice iCE40UltraPlus FPGA系列移动开发平台(MDP)方案

Lattice公司的iCE40UltraPlus FPGA系列是超低功耗FPGA和传感器管理器,具有大电流IR LED驱动器,1Mb SRAM,DSP区块,以及其它查找表(LUT),支持移动设备的常开语音识别功能.器件具有灵活的逻辑架构,其中两个器件的LUT从2800到5280,提供WLCS和QFN封装,采用先进的40nm低功耗技术,待机电流低到100 μA,主要用在常开的语音识别应用,智能手机,平板电脑,手持消费类电子,手持通信和工业设备,多传感器管理,传感器预处理和传感器融合,常开传感器应用以及USB 3.1 Type C电缆检测/电源供给.本文介绍了iCE40UltraPlus FPGA系列主要特性,框图,sysDSP功能框和DSP框图,以及iCE40 UltraPlus移动开发平台(MDP)板主要特性,框图,电路图和材料厂清单.

iCE40UltraPlus family from Lattice Semiconductor is an ultra-low power FPGA and sensor manager designed for ultra-low power mobile applications, such as smartphones, tablets and hand-held devices. iCE40UltraPlus is compatible with Lattice’s iCE40 Ultra family devices, containing all the functions iCE40 Ultra family has except the high current IR LED driver. In addition, the iCE40 UltraPlus features an additional 1 Mb SRAM, additional DSP blocks, with additional LUTs, all which can be used to support an always-on Voice Recognition function in the mobile devices, without the need to keep the higher power consuming voice codec on all the time.
