I/O Structures in IGLOO and ProASIC3 Devices

v1.1
Low-Power Flash Device I/O Support
The low-power flash families listed in
Table 7-1 support I/Os and the functions described in this
document.
Actel's low-power flash devices (listed in
Table 7-1) 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 exit from the ultra-low power mode, which consumes as little as 5 W, while retaining SRAM
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.
IGLOO Terminology
In documentation, the term IGLOO families or IGLOO devices refers to all IGLOO families as listed in
Table 7-1. 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 7-1. Where the information applies to only one family or limited devices, these
exclusions will be explicitly stated.
