Lattice iCE40超低功耗非易式FPGA开发方案
Lattice公司的iCE40系列是超低功耗非易式FPGA器件,查找表(LUT)从384到7680.此外还具有嵌入区RAM(EBR),非易失可配置存储器(NVCM)和锁相环(PLL),非常适用在低成本量大的消费类和系统应用.本文介绍了iCE40系列主要特性和iCE40LP/HX 1K器件架构图,以及iCE40 16-WLCSP评估板主要特性,电路图和材料清单.
The iCE40 family of ultra-low power, non-volatile FPGAs has five devices with densities ranging from 384 to 7680 Look-Up Tables (LUTs). In addition to LUT-based, low-cost programmable logic, these devices feature Embedded Block RAM (EBR), Non-volatile Configuration Memory (NVCM) and Phase Locked Loops (PLLs). These features allow the devices to be used in low-cost, high-volume consumer and system applications. Select packages offer High-Current drivers that are ideal to drive three white LEDs, or one RGB LED. The iCE40 devices are fabricated on a 40 nm CMOS low power process. The device architecture has several features such as programmable low-swing differential I/Os and the ability to turn off on-chip PLLs dynamically. These features help manage static and dynamic power consumption, resulting in low static power for all members of the family.
