Lattice Launches ispMACH™ 4000V Automotive Temperature Range CPLDS

-40 to +125�C ISPTMDevices Feature 5-Volt Tolerant I/Os

HILLSBORO, OR - SEPTEMBER 23, 2002 - Lattice Semiconductor Corporation (NASDAQ: LSCC), today announced that the ispMACH 4000V family now supports the full automotive ambient temperature range of -40 to 125�C . The 3.3-volt ispMACH 4000V family supports a wide range of 3.3V, 2.5V and 1.8V I/O standards and now features 5-volt tolerant I/Os. This high-performance, in-system programmable (ISP) family is well suited for the full range of automotive applications including "in-cabin" electronics and telematics (cell phones, navigation, radio, networking and PC) as well as harsher "under-the-hood" applications such as engine and powertrain control systems management. The ispMACH 4000V automotive temperature grade family provides four logic density solutions from 32 to 256 macrocells, the broadest automotive CPLD product offering in the industry. The devices support 7.5ns pin-to-pin delay (tPD) and 168MHz operating frequencies (fMAX). Typical standby power consumption for the four devices is approximately 40mW, allowing these devices to support power-conscious applications as well. The family includes multiple density-I/O combinations in Thin Quad Flat Pack (TQFP) packages ranging from 44 to 176 pins.

"We are pleased to be able to offer our industry-leading ispMACH 4000V CPLD product family to the automotive design community," said Stan Kopec, Lattice vice president of corporate marketing. "The ispMACH 4000V family delivers the performance and flexibility required to implement next-generation automotive electronics systems cost-effectively."

The ispMACH 4000V automotive family provides optimal logic implementation for many glue logic, state machine, decoder, bridging, power-up, and signal handshaking functions. These functions are critical for the implementation of many automotive applications. Adding extra value, the in-system programmable nature of these devices allows their logic functions to be quickly reconfigured or upgraded over time via a simple IEEE 1149.1-compatible Boundary Scan port, minimizing maintenance costs. Full Boundary Scan test capability also helps to minimize the time required to diagnose problems within automotive electronics systems that use the devices.

Supports LVTTL and Multiple LVCMOS Standards
The ispMACH 4000V automotive devices also have two I/O banks, each with their own power supply pin that can be set at the appropriate voltage to support LVTTL and LVCMOS 3.3, 2.5, and 1.8-volt outputs. Device input buffers have programmable thresholds that support the above standards independent of the I/O bank output voltage. In addition, the devices can also tolerate 5V-input voltages on pins programmed for LVCMOS 3.3 operation, a key capability in interfacing with older 5V-based modules. Through these features, the devices can support the multiple voltage requirements found increasingly in automotive systems.

Design Tools
The ispMACH 4000V automotive family is supported by Lattice's ispLEVER™ design tools. The ispLEVER tools, Lattice's platform for next-generation logic design, provide designers with rapid access to the performance of the ispMACH 4000V devices while maximizing resource utilization. This is achieved through timing driven placement & routing coupled with optimized synthesis support from vendors such as Exemplar and Synplicity. Additional third-party EDA tool support is provided through industry standard EDIF netlist import and export. The ispLEVER software is available in PC as well as UNIX workstation versions.

Price and Availability
The automotive temperature devices are offered in 44-TQFP, 48-TQFP, 100-TQFP, 128-TQFP and 176-TQFP packaging. For high-volume applications beginning in 2003, pricing for the ispMACH 4032V is projected to be less than $1.00.
