Configuration
MAX 7000B 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 7000B
device for either high-speed or low-power operation. 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 7000B device outputs can be programmed to meet a variety of
system-level requirements.
MultiVolt I/O Interface
The MAX 7000B device architecture supports the MultiVolt I/O interface
feature, which allows MAX 7000B devices to connect to systems with
differing supply voltages. MAX 7000B devices in all packages can be set
for 3.3-V, 2.5-V, or 1.8-V pin operation. These devices have one set of V
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, 2.5-V, or 1.8-V power
supply, depending on the output requirements. When the VCCIO pins are
connected to a 1.8-V power supply, the output levels are compatible with
1.8-V systems. 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
