Learn how to get more signal chain from the MCU in factory automation applications
As factories become increasingly smarter, so does we have useful to produce the sensors, automation and equipment that controls and monitors these installations. Microcontrollers (MCUs) will need to efficiently accommodate various kinds of sensing and measurement applications, in particular those between sensing of, humidity, temperature, power current, lethal, many other conditions or parameters. One fashion to address the demand for adaptability is by integrated flexible analog signal-chain configurations throughout the MCU that may be adjusted to meet specific application needs.
This integrated signal-chain approach can be a key element in the new MSP430FR23xx MCU family, with multiple configurable smart analog combo peripherals. The smart analog combo comprises several analog signal-chain elements including an operational amplifier (op amp) with programmable gain amplifier (PGA) capability plus a 12-bit digital-to-analog converter (DAC). These peripherals offer many configuration options, making it possible to configure the inner signal path depending on the job. Figure 1 is actually a high-level block diagram of a smart analog combo module.
