MAX 3000A Programmable Logic Device Family Data Sheet  
MAX 3000A devices offer a power–saving mode that supports low-power  
Programmable  
Speed/Power  
Control  
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 3000A  
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 (tLPA) for the tLAD, tLAC, tIC  
,
tACL, tEN, tCPPW and tSEXP parameters.  
MAX 3000A device outputs can be programmed to meet a variety of  
system–level requirements.

Configuration  
MultiVolt I/O Interface  
The MAX 3000A device architecture supports the MultiVolt I/O interface  
feature, which allows MAX 3000A devices to connect to systems with  
differing supply voltages. MAX 3000A 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  
V
CC pins for internal operation and input buffers (VCCINT), and another  
set for I/O output drivers (VCCIO).  
The VCCIOpins can be connected to either a 3.3–V or 2.5–V power supply,  
depending on the output requirements. When the VCCIOpins are  
connected to a 2.5–V power supply, the output levels are compatible with  
2.5–V systems. When the VCCIOpins 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 nominally 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 11 summarizes the MAX 3000A MultiVolt I/O support.
