Input/Output Blocks
To meet complex system demands, the ProASICPLUS
family offers devices with a large number of user I/O
pins; up to 712 on the APA1000. Table 2-3 shows the
available supply voltage configurations (the PLL block
uses an independent 2.5 V supply on the AVDD and
AGND pins). All I/Os include ESD protection circuits. Each
I/O has been tested to 2000 V to the human body model
(per JESD22 (HBM)).
Six or seven standard I/O pads are grouped with a GND
pad and either a VDD (core power) or VDDP (I/O power)
pad. Two reference bias signals circle the chip. One
protects the cascaded output drivers, while the other
creates a virtual VDD supply for the I/O ring.
I/O pads are fully configurable to provide the maximum
flexibility and speed. Each pad can be configured as an
input, an output, a tristate driver, or a bidirectional
buffer (Figure 2-6 and Table 2-4).

Description
I/O pads configured as inputs
Selectable 2.5 V or 3.3 V threshold levels
Optional pull-up resistor
Optionally configurable as Schmitt trigger input. The Schmitt trigger input option can be
configured as an input only, not a bidirectional buffer. This input type may be slower than
a standard input under certain conditions and has a typical hysteresis of 0.35 V. I/O macros
with an "S" in the standard I/O library have added Schmitt capabilities.
