PFU Blocks
The core of the LatticeECP3 device consists of PFU blocks, which are provided in two forms, the PFU and PFF.
The PFUs can be programmed to perform Logic, Arithmetic, Distributed RAM and Distributed ROM functions. PFF
blocks can be programmed to perform Logic, Arithmetic and ROM functions. Except where necessary, the remain-
der of this data sheet will use the term PFU to refer to both PFU and PFF blocks.
Each PFU block consists of four interconnected slices numbered 0-3 as shown in Figure 2-2. Each slice contains
two LUTs. All the interconnections to and from PFU blocks are from routing. There are 50 inputs and 23 outputs
associated with each PFU block.
