Actel ProASIC3 Commercial Qualification Completed

Single-Chip, Low-Cost, Low-Power and Secure Flash-Based Devices Now Shipping into High-Volume Applications

MOUNTAIN VIEW, Calif., February 21, 2006 — Actel Corporation (Nasdaq: ACTL), the leader in single-chip programmable logic solutions, today announced the commercial qualification of its low-cost, flash-based ProASIC3 field-programmable gate arrays (FPGAs) and M7 ProASIC3 devices, which support use of CoreMP7, Actel's royalty- and license-free soft ARM7 processor core. The commercial-qualified ProASIC3 devices offer low total system cost, high performance, low power and high security advantages highly sought by designers of consumer, communications and handheld applications.

"With the reprogrammability benefits of Actel's commercial temperature-grade ProASIC3 FPGAs, Quixant can securely add features to our QX-10 platform without changing PCB design or re-spinning an ASIC," said Jon Jayal, hardware design manager for Quixant, a provider of secure embedded computing platforms for manufacturers of casino slot machines.

"With the ProASIC3 devices, we're delivering an FPGA with unprecedented levels of features and performance at the lowest total system cost," said Martin Mason, director, silicon product marketing for Actel. "Propelled by the family's low unit costs, which start at $1.50 in volume, the low-power ProASIC3 FPGAs are quickly being adopted by customers in the automotive, consumer, medical and industrial markets. In addition, as we rollout the remaining members of the ProASIC3/E families throughout 2006, we expect the acceptance of Actel's ProASIC3/E and ARM-ready ProASIC3 devices to continue growing at a rapid pace."

ProASIC3 Family Leads in Low Power

For power-conscious applications, the ProASIC3 and ARM7-ready M7 ProASIC3 FPGAs deliver the lowest typical stand-by power consumption per usable gate of any in-system programmable (ISP) FPGA available in the market. They deliver three times longer battery life on average when compared to alternative solutions. In addition, the ProASIC3 FPGAs meet the Level-0 live at power-up (LAPU) specification, meaning they are operational between power-on and power-up. Level-0 LAPU devices offer up to 4,000 times better power-on response time than competing SRAM-based FPGAs.

Additional Device Capability Provides Unique Solution

ProASIC3 and ARM7-ready ProASIC3 FPGAs contain 1,024 bits (128 bits x 8 pages) of on-chip user nonvolatile flash memory and six clock conditioning circuits, including up to six on-board analog phase-locked loops (PLLs). The devices support up to eight I/O banks with up to 616 I/Os and up to 19 advanced single-ended and dual-ended I/O standards.

The devices also provide secure ISP capability through on-chip 128-bit AES decryption and built-in flash key storage technology. This capability enables easy and secure field upgrades and helps protect system IP by preventing reverse engineering and cloning.

About the ProASIC3 Family

Actel's ProASIC3 family delivers 64-bit, 66MHz PCI performance and is the industry's first device with on-chip user flash memory. The device family helps to lower overall system costs by eliminating the need for various components on the system board. For example, the single-chip devices require no external boot prom or microcontroller to support device programming, and the Level-0 LAPU feature of the ProASIC3 devices eliminates the need for an external CPLD to get the system running during power-up. Using fewer components reduces board space, which increases reliability, simplifies inventory management and lowers total system costs by as much as 70 percent compared with similar SRAM-based FPGA solutions.
