The IGLOO family of flash FPGAs, based on a 130-nm flash process, offers the lowest power FPGA, a single-chip solution, small footprint packages, reprogrammability, and an abundance of advanced features. The Flash*Freeze technology used in IGLOO devices enables entering and exiting an ultra-low power mode that consumes as little as 5 μW while retaining SRAM and register data. Flash*Freeze technology simplifies power management through I/O and clock management with rapid recovery to operation mode. The Low Power Active capability (static idle) allows for ultra-low power consumption (from 12 μW) while the IGLOO device is completely functional in the system. This allows the IGLOO device to control system power management based on external inputs (e.g., scanning for keyboard stimulus) while consuming minimal power. Nonvolatile flash technology gives IGLOO devices the advantage of being a secure, low power, singlechip solution that is live at power-up (LAPU). IGLOO is reprogrammable and offers time-to-market benefits at an ASIC-level unit cost. These features enable designers to create high-density systems using existing ASIC or FPGA design flows and tools. IGLOO devices offer 1 kbit of on-chip, reprogrammable, nonvolatile FlashROM storage as well as clock conditioning circuitry based on an integrated phase-locked loop (PLL). The AGL015 and AGL030 devices have no PLL or RAM support. IGLOO devices have up to 1 million system gates, supported with up to 144 kbits of true dual-port SRAM and up to 300 user I/Os. M1 IGLOO devices support the high-performance, 32-bit Cortex-M1 processor developed by ARM for implementation in FPGAs. Cortex-M1 is a soft processor that is fully implemented in the FPGA fabric. It has a three-stage pipeline that offers a good balance between low power consumption and speed when implemented in an M1 IGLOO device. The processor runs the ARMv6-M instruction set, has a configurable nested interrupt controller, and can be implemented with or without the debug block. Cortex- M1 is available for free from Actel for use in M1 IGLOO FPGAs. The ARM-enabled devices have Actel ordering numbers that begin with M1AGL and do not support AES decryption. Flash*Freeze Technology The IGLOO device offers unique Flash*Freeze technology, allowing the device to enter and exit ultra-low power Flash*Freeze mode. IGLOO devices do not need additional components to turn off I/Os or clocks while retaining the design information, SRAM content, and registers. Flash*Freeze technology is combined with in-system programmability, which enables users to quickly and easily upgrade and update their designs in the final stages of manufacturing or in the field. The ability of IGLOO V2 devices to support a wide range of core voltage (1.2 V to 1.5 V) allows further reduction in power consumption, thus achieving the lowest total system power. When the IGLOO device enters Flash*Freeze mode, the device automatically shuts off the clocks and inputs to the FPGA core; when the device exits Flash*Freeze mode, all activity resumes and data is retained. The availability of low power modes, combined with reprogrammability, a single-chip and single-voltage solution, and availability of small-footprint, high pin-count packages, make IGLOO devices the best fit for portable electronics.
