MSP430FR2355 Mixed-Signal Microcontroller [Copy link]

The MSP430FR215x and MSP430FR235x microcontrollers (MCUs) are part of the MSP430 MCU Value Line family of ultra-low-power, low-cost devices for sensing and measurement solutions. The MSP430FR235x MCUs integrate four configurable signal chain blocks called 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 the system while reducing BOM and PCB size. The device also includes a 12-bit SAR ADC and two comparators. Both the MSP430FR215x and MSP430FR235x MCUs support an extended temperature range of –40° to 105°C, so higher temperature industrial applications can benefit from the FRAM data logging capabilities of these devices. This extended temperature range allows developers to meet the requirements of applications such as smoke detectors, sensor transmitters, and circuit breakers.

The MSP430FR215x and MSP430FR235x MCUs feature a powerful 16-bit RISC CPU, 16-bit registers, and constant generators to help achieve maximum coding efficiency. A digitally controlled oscillator (DCO) typically allows the device to wake up from a low-power mode to an active mode in less than 10s.

The MSP430 ultra-low-power (ULP) FRAM microcontroller platform combines a unique combination of embedded FRAM and an overall ultra-low-power system architecture, enabling system designers to increase performance while reducing energy consumption. FRAM technology combines the low-power fast write, flexibility and endurance of RAM with the non-volatility of Flash.

The MSP430FR215x and MSP430FR235x MCUs are supported by a broad hardware and software ecosystem with reference designs and code examples to help you quickly start your design. Development kits include the MSP-EXP430FR2355LaunchPad development kit and the MSP-TS430PT48 48-pin target development board. TI also offers free MSP430Ware software, available as a component of the Code Composer Studio IDE desktop and cloud versions (located on the TI Resource Explorer). MSP430 MCUs also offer extensive online collateral, training and online support through the E2E community forum.
