Microsemi's IGLOO family of low-power Flash FPGAs includes IGLOO/e, IGLOO nano, and IGLOO PLUS subfamilies are designed to meet the demand of low power and small footprint requirements of portable and power-conscious electronics. The FPGAs support up to 35K logic elements with up to 504 kbits of true dual-port SRAM, up to six embedded PLLs, and up to 620 user I/Os. Low-power applications that require 32-bit processing can use the Arm® Cortex®-M1 processor without a license fee or royalties in M1 IGLOO devices. The IGLOO FPGA devices are available in small footprints (3 mm x 3 mm, 4 mm x 4 mm, 5 mm x 5 mm, 6 mm x 6 mm, and 8 mm x 8 mm), high-density, chip-scale, and quad, flat, no-lead packages.

The Flash*Freeze technology used in IGLOO devices enables easy entry and exit from low-power mode which consumes as little as 2 µW while retaining SRAM and register data. Flash*Freeze technology simplifies power management through I/O and clock management without a need to turn off voltages, I/Os, or clocks at the system level. In Flash*Freeze mode, power drops to as low as 2 µW, and no additional components are required to turn off I/Os or clocks while preserving the design information, SRAM content, and registers. I/Os can maintain their state during Flash*Freeze mode. Entering and exiting Flash*Freeze mode takes less than 1 µs. The IGLOO families support up to 3 million system gates with up to 504 kbits of true dual-port SRAM, up to six embedded PLLs, and up to 620 user I/Os. Low-power applications that require 32-bit processing can use the Arm Cortex-M1 processor without license fee or royalties in M1 IGLOO devices. Developed specifically for implementation in FPGAs, Cortex-M1 offers an optimal balance between performance and size to minimize power consumption.
