Overview
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.

SLG4IOEXP-DMO
Active
GreenPAK GPIO Expander Demonstration Board
The SLG4IOEXP-DMO is a GPIO expander demonstration board. Many programmable mixed-signal products include an I2C block which makes these components perfect for a GPIO expander allowing you to add new features, logic, timing, and sensing to already highly integrated designs.
