Lattice iCE40 Ultra系列FPGA开发方案
Lattice公司的iCE40 Ultra系列是超低功耗FPGA和传感器管理器件,采用先进的40nm超低功耗工艺,集成了能和所有移动传感器和应用处理器接口的SPI和I2C区块,还集成了10kHz(LFOSC)和48MHz(HFOSC)的片上振荡器,待机电流低至71uA,主要用于智能手机,平板电脑,手持通信设备厂,多传感器管理应用,传感器预处理和传感器融合以及常开传感器应用.本文介绍了iCE40 Ultra系列FPGA主要特性, iCE5LP-4K器件框图和DSP框图, iCE40 Ultra系列FPGA分接板主要特性和框图,电路图和材料清单.
iCE40 Ultra family is an ultra-low power FPGA and sensor manager designed for ultra-low power mobile applications, such as smartphones, tablets and hand-held devices. The iCE40 Ultra family includes integrated SPI and I2C blocks to interface with virtually all mobile sensors and application processors. The iCE40 Ultra family also features two on-chip oscillators, 10 kHz and 48 MHz. The LFOSC (10 kHz) is ideal for low power function in always-on applications , while HFOSC (48 MHz) can be used for awaken activities.
