Slices
Slices 0-3 contain two LUT4s feeding two registers. Slices 0-2 can be configured as distributed memory. Table 2-1
shows the capability of the slices in PFU blocks along with the operation modes they enable. In addition, each PFU
contains logic that allows the LUTs to be combined to perform functions such as LUT5, LUT6, LUT7 and LUT8.
The control logic performs set/reset functions (programmable as synchronous/ asynchronous), clock select, chip-
select and wider RAM/ROM functions.
Table 2-1. Resources and Modes Available per Slice
Figure 2-4 shows an overview of the internal logic of the slice. The registers in the slice can be configured for posi-
tive/negative and edge triggered or level sensitive clocks. All slices have 15 inputs from routing and one from the
carry-chain (from the adjacent slice or PFU). There are seven outputs: six for routing and one to carry-chain (to the
adjacent PFU). Table 2-2 lists the signals associated with Slices 0-3.

For Slices 0 and 1, memory control signals are generated from Slice 2 as follows:
• WCK is CLK
• WRE is from LSR
• DI[3:2] for Slice 1 and DI[1:0] for Slice 0 data from Slice 2
• WAD [A:D] is a 4-bit address from slice 2 LUT input
