Lowest-Power, Smallest-Package, Low-Density FPGAs


The IGLOO® series of ultra-low density FPGAs includes the IGLOO/e, IGLOO nano and IGLOO PLUS families of devices. As the industry's lowest-power FPGAs, IGLOO FPGA families are designed to meet the low-power and small-footprint requirements of today's portable and power-conscious electronics.

The low-power IGLOO FPGA series supports up to 35K Logic Elements (LEs) with up to 504 Kb of true dual-port SRAM, up to six embedded PLLs and up to 620 user I/Os. If your low-power application requires 32-bit processing, you can use the Arm® Cortex®-M1 processor that is available with IGLOO M1 devices without license fees or royalties.

Flash*Freeze Technology

The Flash*Freeze technology used in IGLOO devices enables easy entry and exit from low-power mode in less than 1 µs. It consumes as little as 2 µW while retaining design information, SRAM content and register data. Flash*Freeze technology simplifies power management through I/O and clock management, without needing to turn off voltages, I/Os or clocks at the system level. I/Os can maintain their state during Flash*Freeze mode.

Small-Footprint Packages

IGLOO FPGAs are true single-chip devices that do not require configuration or other support components. They are available in a variety of small-footprint packages with high I/O pin count to match design needs. The IGLOO family is offered in  small-form-factor (3 × 3, 4 × 4, 5 × 5, 6 × 6 and 8 × 8 mm), high-density chip-scale packages and quad flat no-lead packages.

The IGLOO family of reprogrammable and full-featured flash FPGAs is designed to meet the low-power and area requirements of today’s portable electronics. Based on nonvolatile flash technology, the 1.2 V to 1.5 V operating voltage family offers the industry’s lowest power consumption—as low as 5 μW. The IGLOO family supports up to 35K logic elements with up to 504 kbits of true dualport 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 fees or royalties in M1 IGLOO devices. Developed specifically for implementation in FPGAs, Cortex-M1 devices offer an optimal balance between performance and size to minimize power consumption.

IGLOO nano FPGAs


Our IGLOO nano series of low-power FPGAs offers groundbreaking possibilities in power, size and operating temperature. Available in logic densities from 100 LEs to 3K LEs, the 1.2V to 1.5V IGLOO nano devices have been designed for high-volume applications where power and size are key decision criteria.

Largest Selection of Small-Footprint Packages

The IGLOO nano series also offers the largest selection of small-footprint packages, including the industry's smallest 3 × 3 mm micro chip scale package and six distinctive packages at 8 × 8 mm or less. This small size, combined with the lowest-power FPGA available, starting at just 2 µW, opens new opportunities for designers of battery-powered handheld applications.

With the lowest power and smallest size in the industry, IGLOO nano devices are ideal for independent level shifting to enable support for varying voltage levels, I/O expansion or multiplexing, adapting to changing standards, and when embedded security is required to ensure fidelity of valuable intellectual property.

Key Features


  • Ultra-low power in Flash*Freeze mode, as low as 2 µW
  • Variety of small-footprint packages as small as 3 × 3 mm
  • Best system performance of 250 MHz
  • Enhanced commercial temperature
  • Reprogrammable Flash technology
