Overview
Description
The SLG46531 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 SLG46531. This highly versatile device allows a wide variety of mixed-signal functions to be designed within a very small, low power single integrated circuit.
