Actel's A500K180 and A500K270 flash-based ProASIC 500K field programmable gate array (FPGA) devices, at 369 000 and 473 000 system gates, respectively, represent the highest density, nonvolatile, single-chip, 'live-at-power-up', reprogrammable solutions on the market. Actel's ProASIC FPGAs make it possible to create high-density systems using existing ASIC or FPGA design flows and tools. The manufacturer says these devices are suited for a range of system-critical applications such as optical networking, advanced avionics and industrial controls, in which instant-on operation is needed to ensure that power-on latency does not compromise system functionality.
Implemented in a standard CMOS logic process, the A500K180 and -270 devices combine low power and flash-based nonvolatility with an ASIC-like architecture. This delivers predictable performance and routing efficiency.
Actel says that, as a programmable device, the ProASIC family reduces time-to-market and minimises design risk and investment, requiring no mask sets or silicon re-spins. Unlike most other PLDs, ProASIC devices operate at very low power, using only one-half of the power consumed by SRAM FPGAs and other PLDs based on look-up tables (LUTs) at the same supply voltage.
The A500K270, the larger of the two devices at 473 000 system gates, offers nearly 27 000 flip-flops and 65 Kb of RAM in 28 blocks of 256 x 9 bits. The 369 000-gate A500K180 offers more than 18 000 flip-flops with 55 Kb of RAM in 24 blocks.
The ProASIC 500K family combines the advantages of ASICs with the benefits of PLDs through its nonvolatile flash technology.
