Description

The SLG46532 provides a small, low power component for commonly used mixed-signal functions. The user creates their circuit
design by programming the one time Non-Volatile Memory (NVM) to configure the interconnect logic, the I/O Pins and the macro
cells of the SLG46532. This highly versatile device allows a wide variety of mixed-signal functions to be designed within a very
small, low power single integrated circuit.

The additional power supply (VDD2) on the SLG46532 provides the ability to interface two independent voltage domains within
the same design. Users can configure pins, dedicated to each power supply, as inputs, outputs, or both (controlled dynamically
by internal logic) to both VDD and VDD2 voltage domains. Using the available macro-cells designers can implement mixed-signal
functions bridging both domains or simply pass through level-translation in both High to Low and Low to High directions.
