The device shown is an EPM570 device. EPM1270 and EPM2210 devices have a similar floorplan with more LABs.
For the EPM240 devices, the CFM and UFM block is rotated left 90 degrees covering the left side of the device.

2–2:
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 output of one LE’s LUT to the adjacent LE for fast
sequential LUT connections within the same LAB. Register chain
connections transfer the output of one LE’s register to the adjacent LE’s
register within an LAB. The Quartus
