MSP430FR2476TRHBR

The MSP430FR247x microcontroller (MCU) is part of a product family of ultra-low-power and low-cost devices for detection and measurement applications. This MCU integrates a 12-bit SAR ADC and a comparator, supporting an operating temperature range from –40°C to 105°C. Its FRAM data logging function is of great significance for industrial applications at higher temperatures. The MSP430FR247x MCU is supported by an ecosystem consisting of software and hardware, with reference designs and code examples available to help kick-start the design process quickly. The development kit includes the MSP - TS430PT48 48-pin target development board. Free MSP430Ware software is also provided. The MSP430 ultra-low-power (ULP) FRAM microcontroller platform combines embedded FRAM with an overall ultra-low-power system architecture, enabling system designers to improve performance while reducing energy consumption. FRAM technology combines the low-power, fast write, flexibility, and durability of RAM with the non-volatility of flash memory. The TI MSP430 series of low-power microcontrollers includes a variety of devices equipped with different peripheral sets to meet the needs of various applications. This architecture, when used in conjunction with multiple low-power modes, is the optimal choice for extending the battery life of portable measurement applications. The MCU features a powerful 16-bit RISC CPU, 16-bit registers, and a constant generator, which helps achieve maximum coding efficiency. The digitally controlled oscillator (DCO) allows the MCU to wake up from a low-power mode to an active mode in less than 10 μs (typical).
