| Lattice MachXO Devices Provide New Low Cost Alternative to CPLDs and
HILLSBORO, OR - Lattice Semiconductor Corporation announced its new MachXO™ family
as well as immediate availability of its first two members, the MachXO256 and MachXO640. This new class of Crossover
Programmable Logic device supports applications that traditionally have been addressed either by high density CPLDs
or low capacity FPGAs, but with a more comprehensive and cost-effective architecture and technology. Through the use
of 130nm non-volatile embedded Flash process technology, and the use of an industry-standard 4-input Look-up Table
(LUT) approach 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.
Not content merely to address traditional CPLD
applications with its MachXO devices, Lattice has added to all family members distributed memory, a low standby
power Sleep mode and the ability to transparently update logic configurations through Lattice's unique TransFR™
technology. In addition, support for Embedded Block RAM (EBR) and phase-locked loop (PLL) clock circuitry, as well
as PCI and LVDS I/O, has been added to the larger family members, providing functionality typically found only in
traditional FPGA architectures. At the same time, the instant on, single-chip and high-speed benefits of previous
generations of Lattice CPLDs, such as its popular MACH® devices, have been preserved.
defined our MachXO products, we took a hard look at the features that customers needed for control, bus-bridging and
interface functions that are most commonly implemented in CPLDs," said Stan Kopec, Lattice vice president of
marketing. "It quickly became obvious that by utilizing the efficiency of a LUT-based architecture, and combining it
with our unique high-performance Flash plus SRAM technology, we would be able to provide a significantly lower cost
per function, even as we were able to add features that are extremely important in the implementation of today's
bridging and interface functions."
The MachXO logic
devices are built on a low cost 130nm embedded Flash process technology that enables instant-on operation in a
single chip, a feature essential to many CPLD applications. Pin-to-pin delays as fast as 3.5ns allow the devices to
address the high-speed requirements of contemporary system designs. The technology utilizes a native 1.2V logic core
that is supported directly by "E" versions of the MachXO devices for the lowest power consumption. An on-chip
voltage regulator allows "C" versions of the devices to support 1.8V, 2.5V or 3.3V external power supplies to
support legacy system power requirements.
Four density levels have been defined for the MachXO
family, 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. The MachXO1200 and MachXO2280 support one or two analog PLLs, as well as one
or three 9K-bit embedded block RAM blocks, respectively, yielding 9.2K or 27.6K bits of block memory per device.
Flash back-up allows each EBR block to be configured not only for standard single- and dual-port RAM functions, but
also non-volatile user ROM. Dedicated "hard" FIFO support logic increases the efficiency of FIFO implementations as
well, requiring no additional LUTs for pointer and flag functions.
At the core of each device is
an array of look-up tables that can be used to implement logic and small distributed memories. This array is
surrounded by flexible I/Os that can implement a variety of popular I/O standards such as LVCMOS and, on the larger
devices, PCI and LVDS.
A Sleep mode offers up to a 100x reduction in standby power, supporting
those applications that demand low power. The devices also support Lattice's unique TransFR (Transparent Field
Reconfiguration) technology that 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 significantly disrupting system operation, enabling the flexibility of field logic updates while maintaining
'5 nines' (99.999%) or better system availability.
Design Tools and Evaluation Board Support
Complete timing driven design for the MachXO devices is included in the Lattice ispLEVER® design
tool suite. Mentor Graphics' Precision RTL Synthesis and Synplicity's Synplify synthesis tools support VHDL and
Verilog design entry, and the ispLEVER software provides a comprehensive suite of implementation, verification and
The ispLEVER 5.0 Service Pack 1 is available for immediate download from the
Lattice web site. Evaluation boards for the MachXO256 and MachXO640 devices also are available for purchase,
starting at $99.
MachXO devices are suitable for the
implementation of 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. These applications are found in
a wide variety of end-markets, including Automotive, Consumer, Communications, Computing, Industrial, Medical,
Military and Networking
