PFU Blocks
The core of the MachXO devices consists of PFU and PFF blocks. 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 Distributed ROM functions. Except where necessary, the remainder 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 2-4. There are 53 inputs
and 25 outputs associated with each PFU block.

Slice
Each Slice contains two LUT4 lookup tables feeding two registers (programmed to be in FF or Latch mode), and
some associated logic that allows the LUTs to be combined to perform functions such as LUT5, LUT6, LUT7, and
LUT8. There is control logic to perform set/reset functions (programmable as synchronous/asynchronous), clock
select, chip-select, and wider RAM/ROM functions. Figure 2-5 shows an overview of the internal logic of the Slice.
The registers in the Slice can be configured for positive/negative and edge/level clocks.
