Det skal være lettere at evaulere PLD-designs

Lattice introducerer low-cost 'breakout' boards, der baner vej for at accelerere PLD hardwaredesigns (in english).

Lattice Semiconductor has announced the immediate availability of three new low-cost I/O Breakout Boards: the MachXO 2280 Breakout Board, the ispMACH 4256ZE Breakout Board and the Power Manager II POWR1014A Breakout Board. 

Lattice Breakout Board Evaluation Kits offer a convenient way for users to accelerate hardware evaluation and prototyping by providing easy access by hand to densely spaced PLD I/Os and pre-wired power and programming connections.  For common end applications like I/O expansion and bridging, PLDs offer high I/O density at a low cost.  This has made PLDs the preferred solution instead of discrete logic ICs or an application processor with more I/Os.       

Breakout Boards provide a convenient way to access the fine-pitch pins or balls of a PLD package.  For example, the center-to-center spacing of the package balls of the 256-ball BGA package of the MachXO 2280 Breakout Board is only 1.00 mm BSC (Basic Spacing between Centers).  Electrical traces of the Breakout Board connect each I/O to header landings that have 2.54 mm (100 mil / 0.1 inch) centered holes. 

By adding test probes, jumper wires or pin headers to the header landings, engineers can easily evaluate the MachXO sysI/O Buffer, ispMACH 4000ZE I/O cells, or POWR1014A voltage monitors, high-voltage FET drivers, and open drain outputs.

Each Breakout Board is 3” x 3” and features a USB B-mini connector for power and programming, an LED array and a prototype area.  All Lattice Breakout Boards provide an easy to use platform for evaluating and designing with the MachXO 2280 PLD, ispMACH 4256ZE CPLD or the ispPAC-POWR1014A Power Manager II. 

Along with the board and USB programming cable, each kit includes a pre-loaded hardware test program.  Using Lattice design tools that are provided free of charge, the user can reprogram the on-board PLD device to evaluate custom designs. 

- These boards significantly reduce the effort and cost required to adopt and evaluate PLD and mixed signal devices.  In fact, users can verify correct board operation in minutes and then connect Breakout Boards directly to their prototyping platforms and test equipment.  Designers will also appreciate access to the schematic and PCB CAD artwork files available from the Lattice website, says Gordon Hands, Lattice's Director of Marketing for Low Density and Mixed-Signal Solutions. 

- For this evaluation kit project, Lattice took advantage of the turnkey services of Lattice LEADER Design Services Partner Axelsys of Fremont, California.  Axelsys provided us with a quick time-to-market using their full turnkey product solution with PLD design, PCB schematic and layout design, PCB fabrication and assembly, and kit packaging.
