PWM 风扇控制器- WISHBONE 兼容参考设计。脉宽调制(PWM) 是一种以数字方式控制模拟电路的流行技术。 PWM 使用矩形脉冲波，其脉冲宽度经过调制，导致波形平均值发生变化。在此 PWM 实现中，流经 MOSFET 电路的电流控制发送至风扇负载的电量。该参考设计使用 PLD 和 ...

HILLSBORO, OR, Nov 08, 2010 --Lattice Semiconductor Corporation (NASDAQ: LSCC) today unveiled its new MachXO2(TM) PLD family, which offers designers of low-density PLDs an unprecedented mix of low ...

FPGAs are supremely flexible and powerful devices. However, they usually come in QFP or BGA packages that are altogether difficult for hobbyists to play with. The DIP-FPGA breakout board aims to solve ...

Lattice Semiconductor MachXO2 可编程逻辑器件 (PLD) 由六个超低功耗、瞬时启动、非易失性 PLD 组成，提供从 256 到 6864 个查找表 (LUT) 的密度。此外，来自 Lattice Semiconductor 的 MachXO2 系列 PLD 提供多种功能，例如嵌入式块 RAM (EBR)、分布式 RAM 和用户闪存 (UFM)，这些功能允许 ...

The sheer range of FPGA applications has led to the development of an array of different devices, each with individual strengths and weaknesses. It has never been more important to know your FPGA. The ...

[17:52:52] <cr1901> At some point I'll add MachXO2 Flash programming if no one has done it yet, but right now I've been preoccupied [17:54:51] <trabucayre> Could you open an issue to that? It's a good ...

Add a description, image, and links to the lattice-machxo2 topic page so that developers can more easily learn about it.

There was a time when making a radio receiver involved significant work, much winding of coils, and tricky alignment of circuitry. The advent of Software Defined Radio (SDR) has moved a lot of this ...

Lattice公司的MachXO2系列是超低功耗的非易失PLD器件，容量从256到6864查找表（LUT），19个到 335个 I/O。此外，器件还集成了嵌入区块RAM（EBR）（多达240Kb），分布式RAM(多达54kb)，用户闪存（UFM）(多达3256kb)，PLL以及SPI，I2C和JTAG等接口。待机功耗低到19uW，主要用在低 ...

Last Friday, I wrote about Fipsy, a $10 breadboard-friendly FPGA board powered by Lattice Semi MachXO2 FPGA with 256 LUTs, but I then remember I had covered a board somewhat similar with TinyFPGA ...
