I/Os with Advanced I/O Standards
The ProASIC3 family of FPGAs features a flexible I/O structure, supporting a range of voltages (1.5 V,
1.8 V, 2.5 V, and 3.3 V). ProASIC3 FPGAs support many different I/O standards—single-ended and
differential.
The I/Os are organized into banks, with two or four banks per device. The configuration of these banks
determines the I/O standards supported
Table 1-1 • I/O Standards Supported
Each I/O module contains several input, output, and enable registers. These registers allow the
implementation of the following:
ProASIC3 banks for the A3P250 device and above support LVPECL, LVDS, B-LVDS and M-LVDS.
B-LVDS and M-LVDS can support up to 20 loads.
Hot-swap (also called hot-plug, or hot-insertion) is the operation of hot-insertion or hot-removal of a card
in a powered-up system.
Cold-sparing (also called cold-swap) refers to the ability of a device to leave system data undisturbed
when the system is powered up, while the component itself is powered down, or when power supplies
are floating.
Wide Range I/O Support
Actel ProASIC3 devices support JEDEC-defined wide range I/O operation. ProASIC3 supports the
JESD8-B specification, covering both 3 V and 3.3 V supplies, for an effective operating range of 2.7 V to
3.6 V.
Wider I/O range means designers can eliminate power supplies or power conditioning components from
the board or move to less costly components with greater tolerances. Wide range eases I/O bank
management and provides enhanced protection from system voltage spikes, while providing the
flexibility to easily run custom voltage applications.
