SLG46721

8.0 Connection Matrix

The Connection Matrix in the SLG46721 is used to create the internal routing for internal functions of the device once it is

programmed. The registers are programmed from the one-time NVM cell during Test Mode Operation. All of the connection point

for each logic cell within the SLG46721 has a specific digital bit code assigned to it that is either set to active “High” or inactive

“Low” based on the design that is created. Once the 1024 register bits within the SLG46721 are programmed a fully custom circuit

will be created.

The Connection Matrix has 64 inputs and 92 outputs. Each of the 64 inputs to the Connection Matrix is hard-wired to a particular

source macrocell, including I/O pins, LUTs, analog comparators, other digital resources and VDD and VSS. The input to a digital

macrocell uses a 6-bit register to select one of these 64 input lines.

For a complete list of the SLG46721’s register table, see Section 20.0 Appendix A - SLG46721 Register Definition.
