"Best of the Best"

As Portable Design magazine notes, "Every year we review several hundred products. We report the best of these in our magazine and we recognize the best of the best with our Editor's Choice Awards. These products are worthy of the wider recognition that this award will bring."

Five Months to Volume Production

"This is very special recognition for what we believe is a groundbreaking and unique device," said Stan Kopec, Lattice corporate vice president of marketing. "The MachXO crossover PLD satisfies a market need that until now has not been addressed: the application gap between high density CPLDs and low capacity FPGAs. Just five months after our initial announcement, all four MachXO family members are in volume production. The MachXO devices are already making their way into production systems in the computing, consumer, industrial and automotive market segments. The MachXO device's unique architecture, capabilities, price points and density levels make it particularly well suited for portable applications," Kopec concluded.

Defining a New Class of PLD

The MachXO family defines a new class of Crossover Programmable Logic Device. Through the use of 130nm non-volatile embedded Flash process technology that efficiently integrates densities between 256 and 2280 4-input Look-up Tables (LUTs) for logic implementation, these new devices provide system designers with up to 50% lower cost per logic function, yet deliver a dramatic increase in features. Lattice MachXO devices are ideal for a wide array of functions, including bus bridging, interfacing, control logic, clock management, power and reset control, glue logic, memory control and ASIC and FPGA configuration.

Unique MachXO Capabilities

The Lattice MachXO devices incorporate best in class innovations such as Sleep mode and TransFR™ technology. Sleep mode enables up to a 100x reduction in standby power, supporting applications that demand low power. TransFR (Transparent Field Reconfiguration) technology allows the Flash configuration storage to be programmed transparently while the device continues to operate normally from its SRAM configuration storage. The new configuration can be downloaded when convenient from the Flash to the SRAM blocks in milliseconds. TransFR technology allows devices to be updated without disrupting system operation, enabling the flexibility of field logic updates while maintaining "5 nines" (99.999%) or better system availability.

A Broad Selection of MachXO Packaging and Pricing

There are four MachXO device density levels, including 256, 640, 1200 and 2280 LUT devices, with user I/O counts ranging from 78 to 271 I/O. Package options include thin quad flatpack (TQFP), 8mm by 8mm footprint chip-scale BGA (csBGA) and fine-pitch BGA (fpBGA) package styles from 100 to 324 leads.

In high volumes (250K units), the 256 LUT MachXO256 device is priced as low as $1.50, while the 640 LUT MachXO640 device is priced as low as $2.25. Also in high volumes, the 1200 LUT MachXO1200 device is priced as low as $3.50, while the 2280 LUT MachXO2280 device is priced as low as $5.00.
