The MSP430FR2433 microcontroller (MCU) is part of the MSP430TM value line sensing portfolio, TI's lowest-cost family of MCUs for sensing and measurement applications. The architecture, FRAM, and integrated peripherals, combined with extensive low-power modes, are optimized to achieve extended battery life in portable and battery-powered sensing applications in a small VQFN package 4 mm). TI's MSP430 ultra-low-power FRAM microcontroller platform combines uniquely embedded FRAM and a holistic ultra-low-power system architecture, allowing system designers to increase performance while lowering energy consumption. FRAM technology combines the low-energy fast writes, flexibility, and endurance of RAM with the nonvolatility of flash. The MSP430FR2433 MCU is supported by an extensive hardware and software ecosystem with reference designs and code examples to get your design started quickly. Development kits include the MSPEXP430FR2433 LaunchPadTM development kit and the MSPTS430RGE24A 24-pin target development board. TI also provides free MSP430WareTM software, which is available as a component of Code Composer StudioTM IDE desktop and cloud versions within TI Resource Explorer. The MSP430 MCUs are also supported by extensive online collateral, training, and online support through the E2ETM Community Forum. Device Information (1)

Figure 1-1. Functional Block Diagram The MCU has one main power pair of DVCC and DVSS that supplies digital and analog modules. Recommended bypass and decoupling capacitors are 10 F and 0.1 F, respectively, with 5% accuracy. P1 and P2 feature the pin interrupt function and can wake up the MCU from all LPMs, including LPM3.5 and LPM4. Each Timer_A3 has three capture/compare registers, but only CCR1 and CCR2 are externally connected. CCR0 registers can be used only for internal period timing and interrupt generation. Each Timer_A2 has two capture/compare registers, but only is a compare/capture functionality. CCR0 registers can be used only for internal period timing and interrupt generation. In LPM3.5, the RTC module can be functional while the rest of the peripherals are off.
