MSP430FR215x and MSP430FR235x microcontrollers (MCUs) include configurable signal chain elements and extended operating temperature up to 105°C to meet the requirements of industrial systems. The devices are part of the MSP430™ MCU value line portfolio of ultra-low-power low-cost devices for sensing and measurement applications. The MSP430FR235x devices integrate four smart analog combos, each of which can be used as a 12-bit DAC or a configurable programmable gain Op-Amp to meet the specific needs of a system while reducing the BOM and PCB size. The device also includes a 12-bit SAR ADC and two comparators. The MSP430FR215x and MSP430FR235x MCUs all support an extended temperature range from –40° up to 105°C so higher temperature industrial applications can benefit from the devices’ FRAM data-logging capabilities. The extended temperature range allows developers to meet requirements of applications such as smoke detectors, sensor transmitters, and circuit breakers.
