Replace Fixed-Function ICs with Low-Cost Microcontrollers (.PDF Download)

Most engineers have known for years that microcontrollers are the best choice in building new digital products. Legacy TTL and CMOS functional logic devices gave way to single-chip MCUs years ago. Yet some operations are still implemented with fixed-function devices because an MCU seems like expensive overkill in certain cases. Not anymore, though. When the price for a tiny MCU comes down to pennies, it’s time to reconsider the use of fixed-function circuits. Here are some ideas to help
