1 – IGLOO nano Device Overview
General Description
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 nano devices enables entering and exiting an ultra-
low-power mode that consumes nanoPower 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 while the
IGLOO nano device is completely functional in the system. This allows the IGLOO nano 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 nano devices the advantage of being a secure, low-
power, single-chip solution that is live at power-up (LAPU). The IGLOO nano device 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 nano 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 AGLN030 and
smaller devices have no PLL or RAM support. IGLOO nano devices have up to 250 k system gates,
supported with up to 36 kbits of true dual-port SRAM and up to 71 user I/Os.
IGLOO nano devices increase the breadth of the IGLOO product line by adding new features and
packages for greater customer value in high volume consumer, portable, and battery-backed
markets. Features such as smaller footprint packages designed with two-layer PCBs in mind, power
consumption measured in nanoPower, Schmitt trigger, and bus hold functionality make these
devices ideal for deployment in applications that require high levels of flexibility and low cost.
Flash*Freeze Technology
The IGLOO nano device offers unique Flash*Freeze technology, allowing the device to enter and
exit ultra-low-power Flash*Freeze mode. IGLOO nano 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 nano 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.
During Flash*Freeze mode, each I/O can be set to the following configurations: hold previous state,
tristate, HIGH, or LOW.
The availability of low-power modes, combined with reprogrammability, a single-chip and single-
voltage solution, and small-footprint packages make IGLOO nano devices the best fit for portable
electronics.
