MAX 7000B Programmable Logic Device Data Sheet

MAX 7000B devices contain two I/O banks. Both banks support all
standards. Each I/O bank has its own VCCIO pins. A single device can
support 1.8-V, 2.5-V, and 3.3-V interfaces; each bank can support a
different standard independently. Within a bank, any one of the
terminated standards can be supported.

Each MAX 7000B device has two VREF pins. Each can be set to a separate
V
(GTL+, SSTL-2, or SSTL-3) may use either of the two VREF pins. If these
pins are not required as VREF pins, they may be individually
programmed to function as user I/O pins.
