Actel develops FPGAs for use in commerce, industry, military and aerospace industries. The company's products are divided into three large groups:
- FPGA with electrically erasable memory (flash, EEPROM )
Unique FPGAs and SNKs made using the FLASH technology in combination with reliability, confirmed by the history of their successful application, meet the highest requirements for consumption, cost and reliability both in special-purpose equipment and in mass devices for domestic use.
The IGLOO / e family of low-power, multi-programmable FPGAs is designed for use in portable (wearable) battery powered devices. Created using FLASH technology with a core operating voltage from 1.2V to 1.5V, IGLOO / e FPGAs offer the consumer the lowest consumption in the industry - from 5 μW. FPGAs of the IGLOO / e family are available in volumes up to 3,000,000 system gates, with dual-port static RAM up to 504 kbps, have up to 6 integrated PLLs and up to 620 user I / O ports.
The IGLOO PLUS FPGA family offers an unbeatable combination of ultra-low power with advanced I / O port configuration. Compared to the basic IGLOO family, the IGLOO PLUS FPGA family has 64% more I / O ports, with Schmitt triggers for inputs, hot-swap support, and great configuration options in Flash * Freeze mode, such as bus hold mode.
The IGLOO nano FPGA family offers revolutionary opportunities to reduce consumption, size, project development time and cost.
FPGA IGLOO2 , made by FLASH technology, contains inside the 4th generation logic matrix, already successfully used by developers in the SmartFusion2 SoC family, hardware high-speed transceivers for implementing serial data transfer interfaces up to 5 Gb / s and DDR memory controllers. Developers also have access to RAM and ROM arrays and a whole set of custom hardware encryption and data protection controllers. FPGA IGLOO2 has several advantages due to a rich set of functions that allow developers to create highly reliable, high-performance solutions with optimized energy consumption in the field of radio communications, industry, video surveillance, automotive, as well as in medical equipment.
SmartFusion2 is the world's first SoC, which includes a non-volatile FPGA based on Flash technology, a full-fledged hardware processor subsystem based on the ARM Cortex ™ M3 processor with peripherals, as well as 5T6 / c high-speed serial transceivers and DDR memory controllers. The FPGA matrix is built of 4-input logic modules, it has integrated RAM blocks and hardware mathematical blocks optimized for solving DSP problems at frequencies up to 350 MHz. The processor subsystem has the ability to in-circuit debugging (ETM) by standard means, instruction cache, as well as CAN, USB, Gigabit Ethernet interface controllers. High-speed serial transceivers support standard PCIe, XAUI, and, if necessary, can be used with the user protocol implemented in the FPGA. FPGAs from the PolarFire family have some undeniable advantages, thanks to the cost-balanced FPGA architecture and energy optimization.
Chips of the PolarFire family have 50% less power consumption than similar SRAM FPGAs and are focused on applications in many areas, such as: wired and wireless data networks, avionics, exploration, automation of industrial production and the Internet of things.
- FPGA with one-time programmable memory ( RAM , anti-fuse)
MX, eX, SX-A, Axelerator - microcircuits made according to Antifuse technology are once programmable. For all of them, there are prototyping tools based on repeatedly programmable microcircuits. Antifuse technology is based on the restoration of amorphous silicon jumpers during its transition to a highly conductive state under the influence of a programming pulse. A distinctive feature of these microcircuits is that Antifuse jumpers, once programmed, never return to an unprogrammed state, which happens, for example, with burned jumpers.
- FPGA with RAM and high radiation resistance
Radiation-resistant FPGAs Microsemi can be either one-time programmable or with the possibility of multiple programming in the system. One-programmable chips include the RTAX-S / SL, RTAX-DSP families with a guaranteed cumulative dose level of up to 300 kRad and the RTSX-SU family of chips with a cumulative dose of up to 100 kRad. Repeatedly programmable radiation-resistant FPGAs include RT ProASIC3 microcircuits that retain the ability to reprogram in the system with an absorbed radiation dose of up to 15 kRad and maintain their operability at an absorbed dose of 25 kRad, as well as the latest RTG4 family that maintains operability in harsh operating conditions with an accumulated dose above 100 krad
To support consumer FPGAs, Actel provides several versions of the Libero embedded software development environment , as well as hardware (programmers, adapters, demos, and boards).
The successful implementation of FPGAs is facilitated by the availability of a significant number of ready-made modules of “ IP cores ” that allow you to quickly implement solutions that are optimal for a specific task.
Since 1996, FPGAs have been successfully used in Russia in GLONASS, Express-AM, Coronas, Soyuz, Progress and many other satellites, as well as in numerous projects of high-reliability ground equipment.  However, with the introduction of US sanctions against Russia in newly manufactured devices, these FPGAs are replaced by domestic-made microcircuits - the FPGA of the Voronezh Semiconductor Devices Plant, BMK f. "Angstrom" and "NIIME" (Zelenograd), ASIC PJSC "Micron" (Zelenograd).
The main competitors of the company are Altera , Xilinx , Lattice , QuickLogic .
