Lattice Releases 3.3-Volt Family of High I/O ispGDX Devices.

HILLSBORO, Ore.--(BUSINESS WIRE)--July 26, 1999--

-    The ispGDXV(tm) family of 3.3-volt in-system programmable digital
     crosspoint devices support I/O densities from 80 to 240 pins
-    High I/O, in-system programmable devices provide unique solution
     for high integration, board-level signal routing and interfacing

Lattice Semiconductor Corporation (NASDAQ: LSCC) today released the first of a family of high performance, 3.3- volt in-system programmable digital crosspoint devices. Based on a second generation ispGDX architecture, this family delivers highly integrated signal routing and interface solutions for today's high performance electronic systems.

The ispGDX160V is the first member of the new ispGDXV family. The ispGDXV architecture is a functional superset of the earlier 5-Volt ispGDX family with new features, higher I/O options and a 3.3-Volt logic core. The ispGDXV family offers a new programmable MUX width for MUX chaining and supports up to 16:1 real-time multiplexing, a unique capability among programmable devices. The family supports I/O densities from 80 up to 240 and includes other features such as a bus hold latch per I/O, programmable clock enable logic, hot socketing tolerance, output slew rate control and full boundary scan test and in-system programming support (IEEE 1149.1 compliant).

The logic architecture of the ispGDX160V features 160 programmable I/O cells interconnected by a Global Routing Pool (GRP) that delivers fast operation: input-to-output signal delays (Tpd) of 5ns, clock-to-output delays (Tgco) of 5ns and pin-to-pin operating frequencies (Fmax) of 111MHz. It is offered in advanced 208- and 272-ball BGA packages as well as a 208-pin PQFP (plastic quad flat pack) package. The ispGDX160V is available in both commercial and industrial operating ranges.

Like all ispGDX devices, this new device is optimized for digital signal interface and routing applications, and represents a new class of high-density programmable components distinct from complex programmable logic devices (CPLDs) and field programmable gate arrays (FPGAs) that supports board-level rather than chip-level logic interface solutions. The devices are ideal for board-level signal switching and multiplexing applications including wide bus steering, multi-port memory interfaces, and standard interface logic integration.

"The ispGDX160V continues our commitment to systems designers migrating to low-voltage designs," said Steve Stark, Lattice's director of component marketing. "The ispGDXV family supports a wider range of signal routing and interface applications with expanded functionality and I/O count."

ispGDX and ispGDXV devices are supported by Lattice's ispGDX Development System software. Device design in this environment is done using a simple, yet powerful, Lattice Hardware Description Language specifically designed for the ispGDX architecture. It also interfaces to existing 3rd party simulation tools for complete timing simulation in industry standard formats.

Price and Availability

The 5ns speed grade ispGDX160V in the 208 ball BGA package is available now and priced at $9.95 in high volume quantities. Reader Contact: Steve Stark, Director of Component Marketing [phone]

About Lattice Semiconductor and Vantis

Oregon-based Lattice Semiconductor Corporation designs, develops and markets the broadest range of high-performance ISP programmable logic devices (PLDs) and offers total solutions for today's advanced logic designs. Lattice introduced in-system programmability to the logic industry in 1992. In June 1999, Lattice acquired Vantis, the corporation that invented the PAL(R) device and PLD switch matrix architecture, from AMD. With nearly double the R&D and sales resources, the resulting integrated company will focus on delivering logic products that satisfy the performance, density and ease-of-use requirements of its customers.

Lattice/Vantis products are sold worldwide through an extensive network of independent sales representatives and distributors, primarily to OEM customers in the fields of communications, computing, computer peripherals, instrumentation, industrial controls and military systems. Company headquarters are located at 5555 NE Moore Court, Hillsboro, Oregon 97124 USA; Telephone [phone]; FAX [phone].
