MAX II Architecture
Table 2–1 shows the number of LAB rows and columns in each device as
well as the number of LAB rows and columns adjacent to the flash
memory area in the EPM570, EPM1270, and EPM2210 devices. The long
LAB rows are full LAB rows that extend from one side of row I/O blocks
to the other. The short LAB rows are adjacent to the UFM block; their
length is shown as width in LAB columns.
