Configurable Mixed-signal ICs and Asynchronous State Machines Can Optimize Embedded Designs


SoC and MCUs require external circuitry for power management, human interface or connecting to sensors. As a result, there are almost always comparators, op amps, level shifters, various logic and discrete transistors scattered across a design. These SoCs are almost never truly Systems on a Chip.

In some cases, the support logic needed can be swept up into a low-end FPGA. But usually this is not a cost saving over discrete components. It is also an inadequate solution since an FPGA cannot address analog or discrete components. For an embedded device, this challenge will be even more pronounced as an MCU or SoC cannot address all the possible sensor, power, and connectivity options.
