MAX 7000 Programmable Logic Device Family Data Sheet
Programmable
Speed/Power
Control
MAX 7000 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 7000
device for either high-speed (i.e., with the Turbo BitTM option turned on)
or low-power (i.e., with the Turbo Bit option turned off) 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 (tLPA) for the tLAD, tLAC, tIC,
tEN, and tSEXP, tACL, and tCPPW parameters.
Output
Configuration
MAX 7000 device outputs can be programmed to meet a variety of
system-level requirements.
MultiVolt I/O Interface
MAX 7000 devices—except 44-pin devices—support the MultiVolt I/O
interface feature, which allows MAX 7000 devices to interface with
systems that have differing supply voltages. The 5.0-V devices in all
packages can be set for 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 VCCINT pins must always be connected to a 5.0-V power supply.
With a 5.0-V VCCINT level, input voltage thresholds are at TTL levels, and
are therefore compatible with both 3.3-V and 5.0-V inputs.
The VCCIO pins can be connected to either a 3.3-V or a 5.0-V power
supply, depending on the output requirements. When the VCCIO pins are
connected to a 5.0-V supply, the output levels are compatible with 5.0-V
systems. When VCCIO is connected to a 3.3-V supply, the output high is
3.3 V and is therefore compatible with 3.3-V or 5.0-V systems. Devices
operating with VCCIO levels lower than 4.75 V incur a nominally greater
timing delay of tOD2 instead of tOD1.
Open-Drain Output Option (MAX 7000S Devices Only)
MAX 7000S devices provide an optional open-drain (functionally
equivalent to open-collector) output for each I/O pin. This open-drain
output enables the device to provide system-level control signals (e.g.,
interrupt and write enable signals) that can be asserted by any of several
devices. It can also provide an additional wired-OR plane.
