AMI Semiconductor Inc. is making its low-power XPressArray hybrid gate array technology available in a 1.5V version. The original 1.8V version was launched early this year.

The technology can be used for developing cost-effective, pin-compatible ASIC replacements for FPGAs such as the Virtex II from Xilinx Inc. and the Stratix from Altera Corp, the company said. Developers can also use the technology to convert multiple FPGAs to a single XPress Array ASIC, thereby reducing size and component count. Target markets include industrial, automotive, consumer, medical, communications and storage.

ASICs based on the new 1.5V platform offer densities of up to 2.6 million gates and system clock speeds up to 150MHz, which AMI called comparable to the logic performance of leading 1.5V FPGAs.

Hybrid gate arrays can be configured with up to 200,000 internal registers and between 38Kb and 1.4Mb of embedded configurable and initializable memory. Power dissipation is 35nW/MHz - a 30 percent improvement over the 1.8V technology, AMI said.

I/O configurations include support for LVTTL, LVCMOS, PCI, HSTL, SSTL, GTL/+, LV-PECL, LVDS, and BLVDS. The technology works with 1.5, 1.8, 2.5, 3.3, and 5V I/O schemes, and clock-management circuitry includes options for up to 12 all-digital delay-locked loops and four PLLs. Embedded scan test logic is included to ease high-fault-coverage testing, the company said.

XPressArray devices are fabricated in processes from TSMC combined with AMI's metal-finishing technology. Processing expenses for pre-fabricated base array slices can be shared across applications, and metal tooling and manufacturing costs for customized applications are lower than for cell-based processes. So, AMI's technology offers low nonrecurring-engineering costs - $70,000 to $180,000 - and low unit costs ($8.50 to $38) and fast cycle times.

The 1.5V XPressArray platform is supported by AMI's Netrans FPGA-to-ASIC conversion methodology, and by synthesis libraries for commercial synthesizers such as Synplicity's Synplify ASIC and Synopsys' Design Compiler.
