Microsemi expands mid-range FPGA series with IGLOO2

June 19, 2013 // By Graham Prophet
IGLOO2 FPGAs, Microsemi asserts, offer the lowest system cost, highest levels of integration for comparable devices, low power, reliability, and security.

The company targets the FPGA family at industrial, commercial aviation, defence, communications and security applications. Microsemi says that the non-volatile flash-based IGLOO2 FPGAs have the highest number of mainstream FPGA features including general purpose input/outputs (GPIOs), 5G SERDES interfaces, and PCI Express endpoints of any similar device, and feature the industry’s only high-performance memory subsystem.

When compared to other 5G SERDES-based FPGAs under 150k logic elements (LEs), IGLOO2’s high level of integration provides the lowest total system cost while improving reliability, significantly reducing power and systematically protecting customers’ valuable design IP. The IGLOO2 FPGA family requires only two power supplies, versus three for competitive devices; its non-volatile configuration eliminates the requirement for external flash memory, providing the system architect with a higher level of system integration, performance and reliability.

IGLOO2 mainstream FPGAs feature a LUT-based fabric, 5G transceivers, high-speed GPIO, block RAM and DSP blocks in a differentiated, cost- and power-optimised architecture. The architecture offers up to five times more logic density and three times more fabric performance than the previous generation IGLOO family.

A high level of I/O and SERDES integration is necessary for I/O expansion, bridging, system management and co-processing, the company notes, allowing you to use smaller devices for I/O expansion and bridging solutions. This, coupled with the need for only two power supplies and no external configuration devices, reduces overall system cost and board complexity.

FPGA features are complemented by a built-in high-performance memory subsystem (HPMS) that embeds common user functions such as the industry’s largest monolithic embedded SRAM memory blocks. These memories provide fast, predictable low latency to time-critical embedded applications such as video, embedded graphics functions and real-time Ethernet. Included in the HPMS is up to 512 kBytes of flash memory which allows users to store system data such as Ethernet MAC IDs, user keys, system configuration and system personalisation data. This feature also enables secure boot functions for industry leading processors by storing
