Global Resource Support in Low-Power Devices
The low-power flash families listed in
Table 3-1 support the global resources and the functions
described in this document.
Actel's low-power flash devices (listed in
Table 3-1) provide a selection of low-power, secure, live-at-
power-up, single-chip solutions. The nonvolatile flash-based devices do not require a boot PROM and
incorporate FlashLock technology, which provides a unique combination of reprogrammability and
design security without external overhead. Only low-power flash FPGAs can offer these advantages.
Actel IGLOO PLUS FPGAs are the industry-leading 1.2 V ultra-low-power programmable logic
devices (PLDs) and consume 90% less static power and over 50% less dynamic power than PLD
alternatives, while ProASIC3L devices offer a balance of low power and higher performance.
Flash*Freeze technology used in IGLOO, IGLOO PLUS, and ProASIC3L devices enables easy entry to
and register data. IGLOO PLUS also offers the ability to hold I/O state in Flash*Freeze mode.
Flash*Freeze technology simplifies power management through I/O and clock management
without the need to turn off voltages, I/Os, or clocks at the system level. Entering and exiting
Flash*Freeze mode takes less than 1 s.
The Actel Fusion family, based on the highly successful ProASIC3 flash FPGA architecture, has been
designed as a high-performance, mixed-signal Programmable System Chip. Fusion supports many
peripherals, including embedded flash memory, analog-to-digital converter (ADC), high-drive
outputs, RC and crystal oscillators, and real-time counter (RTC). The total available on-chip memory,
including the flash array blocks, is greater than that found in SRAM FPGAs.
IGLOO Terminology
In documentation, the term IGLOO families or IGLOO devices refers to all IGLOO families as listed in
Table 3-1. Where the information applies to only one family or limited devices, these exclusions will
be explicitly stated.
ProASIC3 Terminology
In documentation, the term ProASIC3 families or ProASIC3 devices refers to all ProASIC3 families as
listed in
Table 3-1. Where the information applies to only one family or limited devices, these
exclusions will be explicitly stated.
