ispMACH 4000V/B/C Family Data Sheet
3
The I/Os in the ispMACH 4000 are split into two banks. Each bank has a separate I/O power supply. Inputs can
support a variety of standards independent of the chip or bank power supply. Outputs support the standards com-
patible with the power supply provided to the bank. Support for a variety of standards helps designers implement
designs in mixed voltage environments.
ispMACH 4000 Architecture
There are a total of two GLBs in the ispMACH 4032, increasing to 32 GLBs in the ispMACH 4512. Each GLB has
36 inputs. All GLB inputs come from the GRP and all outputs from the GLB are brought back into the GRP to be
connected to the inputs of any other GLB on the device. Even if feedback signals return to the same GLB, they still
must go through the GRP. This mechanism ensures that GLBs communicate with each other with consistent and
predictable delays. The outputs from the GLB are also sent to the ORP. The ORP then sends them to the associ-
ated I/O cells in the I/O block.
Generic Logic Block
The ispMACH 4000 GLB consists of a programmable AND array, logic allocator, 16 macrocells and a GLB clock
generator. Macrocells are decoupled from the product terms through the logic allocator and the I/O pins are decou-
pled from macrocells through the ORP. Figure 2 illustrates the GLB.

AND Array
The programmable AND Array consists of 36 inputs and 83 output product terms. The 36 inputs from the GRP are
used to form 72 lines in the AND Array (true and complement of the inputs). Each line in the array can be con-
nected to any of the 83 output product terms via a wired-AND. Each of the 80 logic product terms feed the logic
allocator with the remaining three control product terms feeding the Shared PT Clock, Shared PT Initialization and
Shared PT OE. The Shared PT Clock and Shared PT Initialization signals can optionally be inverted before being
fed to the macrocells.
Every set of
fi
ve product terms from the 80 logic product terms forms a product term cluster starting with PT0.
There is one product term cluster for every macrocell in the GLB. Figure 3 is a graphical representation of the AND
Array.
