Note to Figure 2–2:
(1) The device shown is a 5M570Z device. 5M1270Z and 5M2210Z devices have a similar floorplan with more LABs. For 5M40Z, 5M80Z, 5M160Z,
and 5M240Z devices, the CFM and UFM blocks are located on the left side of the device.

Each LAB consists of 10 LEs, LE carry chains, LAB control signals, a local interconnect,
a look-up table (LUT) chain, and register chain connection lines. There are 26 possible
unique inputs into an LAB, with an additional 10 local feedback input lines fed by LE
outputs in the same LAB. The local interconnect transfers signals between LEs in the
same LAB. LUT chain connections transfer the LUT output from one LE to the
