Description
The SLG46538-E provides a small, low-power component for commonly used mixed-signal functions. The user creates their circuit design by programming the one-time programmable (OTP) non-volatile memory (NVM) to configure the interconnect logic, the IO pins, and the macrocells of the SLG46538-E. This highly versatile device allows for 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 SLG46538-E 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 macrocells, 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.
