Accelerate Your Development Time with New MachXO Reference Designs and Development Kit

15 new reference designs and a new $59 Mini Development Kit target low-density applications.

System designers are increasingly turning to the use of programmable logic devices (PLDs) for power-up control and system integration functions in their designs. Compared to ASICs and ASSPs, PLDs offer inherent time-to-market and design flexibility advantages and enable designers to respond to changing market standards and requirements within a compressed window of opportunity. 

The instant-on, easy-to-use MachXO PLD family offers users the benefits of increased system integration by providing embedded memory, built-in PLLs, flexible multi-voltage high performance LVDS I/O and a low-power sleep mode, all in a single device. Designed for a broad range of low-density applications that include general-purpose I/O expansion, control, bus bridging and power-up management functions, the popular MachXO PLD family is used in a variety of end markets such as consumer, automotive, communications, computing, industrial and medical.

In order to accelerate your development time, a total of 19 reference designs, 15 of which are new, and the easy-to-use $59 MachXO Mini Development Kit, are now available for prototyping your low-density applications.

Reference Designs

A comprehensive set of 15 new reference designs has been optimized for the MachXO PLD family. These designs serve as a starting point for designers and cover a wide range of low-density applications. Each reference design includes a web page that provides a brief overview of the design, design documentation and source code. The reference designs can be downloaded from the web pages free of charge.

The MachXO Mini Development Kit

At the heart of the MachXO Mini Development Kit is the MachXO Mini Evaluation Board featuring the MachXO LCMXO2280 device, 2Mbit SPI Flash and 1Mbit SRAM memory, a temperature sensor, an expansion header for I²C and SPI interfaces, and several LEDs and user switches. Using the preloaded mini system-on-chip (mini SoC) design provided with the development kit, you can now test within minutes I²C, SPI, UART and SRAM interfaces in addition to the 8-bit LatticeMico8 microcontroller. You can then build your own designs using the free downloadable reference design source codes, implementing these features in less than an hour.

The MachXO Mini Development Kit

The MachXO Mini Evaluation Board can be powered-up and programmed using a standard USB cable. The MachXO Mini Development Kit includes a USB cable for device programming and quick start documentation. The associated reference designs and free ispLEVER Starter design software can be downloaded from the Lattice website.
