MAX 7000A devices offer a power-saving mode that supports low-power
operation across user-defined signal paths or the entire device. This
feature allows total power dissipation to be reduced by 50% or more
because most logic applications require only a small fraction of all gates to
operate at maximum frequency.
The designer can program each individual macrocell in a MAX 7000A
device for either high-speed (i.e., with the Turbo Bit
or low-power operation (i.e., with the Turbo Bit option turned off). As a
result, speed-critical paths in the design can run at high speed, while the
remaining paths can operate at reduced power. Macrocells that run at low
power incur a nominal timing delay adder (t

MAX 7000A device outputs can be programmed to meet a variety of
system-level requirements.
MultiVolt I/O Interface
The MAX 7000A device architecture supports the MultiVolt I/O interface
feature, which allows MAX 7000A devices to connect to systems with
differing supply voltages. MAX 7000A devices in all packages can be set
for 2.5-V, 3.3-V, or 5.0-V I/O pin operation. These devices have one set of
VCC pins for internal operation and input buffers (VCCINT), and another
set for I/O output drivers (VCCIO).
The VCCIO pins can be connected to either a 3.3-V or 2.5-V power supply,
depending on the output requirements. When the VCCIO pins are
connected to a 2.5-V power supply, the output levels are compatible with
2.5-V systems. When the VCCIO pins are connected to a 3.3-V power
supply, the output high is at 3.3 V and is therefore compatible with 3.3-V
or 5.0-V systems. Devices operating with V
incur a slightly greater timing delay of t
