    MAX 7000A Programmable Logic Device Data Sheet
    Programmable
    Speed/Power
    Control
    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 BitTM option turned on)
    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 (tLPA) for the tLAD, tLAC, tIC,
    tEN, tSEXP, tACL, and tCPPW parameters.
    Output
    Configuration
    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 VCCIO levels lower than 3.0 V
    incur a slightly greater timing delay of tOD2 instead of tOD1. Inputs can
    always be driven by 2.5-V, 3.3-V, or 5.0-V signals.
    Table 12 describes the MAX 7000A MultiVolt I/O support.
