IGLOO

Overview

The Industry's Low-Power FPGAs

The IGLOO® series of ultra-low density FPGAs includes IGLOO/e, IGLOO nano and IGLOO PLUS —the industry's low-power FPGAs. IGLOO FPGA family are designed to meet the demand of low power and small foot print requirements of today's portable and power-conscious electronics.

The IGLOO low-power FPGA family support up to 35K logic elements with up to 504 kbits of true dual-port SRAM, up to 6 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.

The IGLOO FPGA family devices are available in small footprint (3x3, 4x4, 5x5, 6x6 and 8x8 mm), high
density, chip-scale and quad flat no-lead packages.

The IGLOO series includes:

Flash*Freeze Technology

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.

Small Footprint Packages

IGLOO FPGAs are true single-chip devices, do not require configuration or other support components, and offer a variety of small-footprint packages with high I/O pin count to match design needs.The IGLOO family is offered in a small form factor (3x3, 4x4, 5x5, 6x6, and 8x8 mm), high-density, chip-scale packages and quad flat no-lead packages.

IGLOO/e

The IGLOO/e family of low-power flash FPGAs, based on a 130-nm flash process, a single-chip solution, small footprint packages, reprogrammability, and an abundance of advanced features.

The Flash*Freeze technology used in IGLOO/e devices enables entering and exiting an ultra-low power mode while retaining SRAM and register data. Flash*Freeze technology simplifies power management through I/O and clock management with rapid recovery to operation mode.

IGLOO/e devices offer 1 kbit of on-chip, programmable, nonvolatile FlashROM storage as well as clock conditioning circuitry based on 6 integrated phase-locked loops (PLLs). IGLOO/e devices have up to 35K LEs, supported with up to 504 kbits of true dual-port SRAM and up to 620 user I/Os.
M1 IGLOO/e devices support the high-performance, 32-bit ARM® - Cortex-M1™ Processor developed by ARM for implementation in FPGAs. Cortex-M1 is available for free from Microsemi for use in M1 IGLOO/e FPGAs.

Notes:

Each used differential I/O pair reduces the number of single-ended I/Os available by two.
FG256 and FG484 are footprint-compatible packages.
The M1AGL250 device does not support CS196 package.
For AGLE3000 devices, the usage of certain I/O standards is limited as follows: – SSTL3(I) and (II): up to 40 I/Os per north or south bank – LVPECL / GTL+ 3.3 V / GTL 3.3 V: up to 48 I/Os per north or south bank – SSTL2(I) and (II) / GTL+ 2.5 V/ GTL 2.5 V: up to 72 I/Os per north or south bank
When using voltage-referenced I/O standards, one I/O pin should be assigned as a voltage-referenced pin (VREF) per minibank (group of I/Os).
When the Flash*Freeze pin is used to directly enable Flash*Freeze mode and not as a regular I/O, the number of single-ended user I/Os available is reduced by one.
"G" indicates RoHS-compliant packages. See Ordering Information
