[原创]Lattice MachXO2系列超低功耗非易失PLD开发方案

Lattice公司的MachXO2系列是超低功耗非易失PLD器件,共有六个器件,查找表(LUT)从256到6864.此外,基于LUT,低成本可编逻辑这些器件具有嵌入区块RAM(EBR),分布式RAM,用户闪存(UFM),锁相环(PLL),支持预工程源同步I/O,支持先进的配置包括双引导功能和通用功能的硬化版本包括SPI控制器,I2C 控制器和计时器/计数器.这些特性使得这些器件可用在低成本量大的消费类和系统应用.MachXO2系列产品采用65nm非易失低功耗工艺,器件的架构有几个特性如可编低摆动差分I/O和能够关断I/O 组(bank),片上PLL和动态振荡器.这些特性有助管理静态和动态功耗,因此所有系列产品都有低静态功耗.待机功耗低到22 μW.本文介绍了MachXO2系列主要特性,MachXO2-1200和MachXO2-4000器件架构图,PFU框图,Slice框图和PLL框图,以及开发板AK-MACHXO2-7000主要特性及主要元件,布局图和电路图.

The MachXO2™ family of ultra low power, instant-on, non-volatile PLDs has six devices with densities ranging from 256 to 6864 Look-Up Tables (LUTs). In addition to LUT-based, low-cost programmable logic these devices feature Embedded Block RAM (EBR), Distributed RAM, User Flash Memory (UFM), Phase Locked Loops (PLLs), preengineeredsource synchronous I/O support, advanced configuration support including dual-boot capability and hardened versions of commonly used functions such as SPI controller, I2C controller and timer/counter. These features allow these devices to be used in low cost, high volume consumer and system applications.
