SLG46855

GreenPAK Programmable Mixed-Signal Matrix

Connection Matrix

The Connection Matrix in the SLG46855 is used to create the internal routing for internal functional macrocells of the device once

it is programmed. The registers are programmed from the one time programmable (OTP) NVM cell during Test Mode Operation.

The output of each functional macrocell within the SLG46855 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 2048 register bits within the SLG46855 are programmed

a fully custom circuit will be created.

The Connection Matrix has 64 inputs and 96 outputs. Each of the 64 inputs to the Connection Matrix is hard-wired to the digital

output of a particular source macrocell, including IO pins, LUTs, analog comparators, other digital resources, such as VDD and

GND. 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 SLG46855’s register table, see Section 17.
