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.
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, BLVDS and M-LVDS. BLVDS
and M-LVDS can support up to 20 loads.
