ProASICPLUS In-System Reprogrammability Provides Flexibility Needed to Replace TPU Controllers in Superfund World Series Race Cars

MOUNTAIN VIEW, Calif., November 10, 2003 - Actel Corporation (Nasdaq: ACTL) today announced that Life Racing, the electronics design arm of AER (Advanced Engine Research Ltd.), has successfully used Actel's ProASICPLUS industrial-temperature field-programmable gate arrays (FPGAs) to enable unprecedented flexibility and performance in an automotive engine control unit (ECU). Competitive race car engine control units require complex tuning algorithms, optimized for each individual controller device, to manage engine timing. With standard Time Processor Unit (TPU) controllers, this critical software can require significant rework as application requirements change. With Actel's in-system programmability (ISP), Life Racing was able to replace off-the-shelf TPU controllers with the single-chip, live at power-up APA450 ProASICPLUS devices. Implementing a flexible hardware solution enabled Life Racing to shorten software development time, reduce debug requirements and speed overall time to market. Recently, Life Racing's proprietary ECU design, the F88, was successfully used in the first race of the 2003 Superfund World Series - considered to be a critical stepping stone to Formula 1.

"Our core business is race engine control. In a motorsport environment time is everything and everyone is under immense pressure. The flexibility provided by Actel's ProASICPLUS FPGAs allows us to quickly design hardware and decrease overall software development time, which is usually the most pressured activity," said Mark Colby, systems designer at Life Racing. "The ProASICPLUS ISP functionality allows us to accelerate development and testing. Furthermore, we can increase the FPGA functionality post-deployment without the prospect of difficult or expensive chip replacements when upgrading a unit to an extended FPGA design."

Barry Marsh, vice president of product marketing at Actel, said, "Life Racing's selection of our ProASICPLUS FPGA reinforces our long standing commitment to delivering highly reliable solutions for a variety of demanding markets, including in-cab and under-the-hood automotive applications. With a broad portfolio of antifuse products certified to the industry's highest junction temperature, as well as industrial-temperature-grade flash-based FPGAs, customers can confidently choose the FPGA with the range of features that best suits their design requirements."

Within the F88 ECU, the main function of the 450,000-gate APA450 ProASICPLUS FPGA is to derive engine position from the engine's crankshaft trigger wheel signal. The FPGA generates CPU interrupts based on abstract crankshaft angles, rather than the physical trigger wheel tooth positions used in traditional designs, providing increased flexibility and accuracy.

ECUs commonly schedule fuel and ignition actions as timed future events based on engine operating conditions at the point the scheduling code is executed. Changes in operating conditions that occur before the event can result in angular errors, and the scheduling code is often highly dependent on the crankshaft trigger wheel tooth pattern for the engine in question. In the F88, the ProASICPLUS FPGA allows the scheduling code to be independent of signal patterns. The FPGA can also schedule events and continue to tune placement by monitoring engine operating conditions until the event occurs. This increases code efficiency and flexibility and improves control accuracy under dynamic conditions.

The live-at-power-up functionality of the ProASICPLUS device enables designers to eliminate additional components traditionally needed to prevent fuel injector drivers or ignition coil drivers from turning on during power up. For example, a single-chip solution with glue logic instantly available on CPU bus control lines, ProASICPLUS FPGAs enable a reduction in component count and board area.

The Life Racing ECU is currently also being considered for use by commercial road vehicle manufacturers. The flexibility of the unit makes it appropriate for prototyping and R&D environments in which the unit must cope with a variety of engine set ups.

About Actel's ProASICPLUS Family

Actel's nonvolatile, single-chip ProASICPLUS industrial devices, ranging in density from 75,000 to 1-million system gates, are guaranteed to operate at ambient temperatures ranging from -40°C to +85°C. The devices are live at power-up, low power, flash-based solutions and the extended temperature range, coupled with the industry's largest density for flash-based FPGAs, makes these new devices suitable for application-specific integrated circuit (ASIC) alternative applications in the avionics, consumer, industrial control, networking and communications markets.
