　　TI公司的MSP430FR59xx系列产品是混合信号微控制器,是一种超低功耗FRAM平台,集成了FRAM和超低功耗系统架构以及用于各种应用的智能外设.CPU具有16位RISC架构,工作频率高达16MHz,工作电压1.8V-3.6V,工作模式的电流大概为100uA/MHz,待机状态为0.4uA,关断时为0.02uA,主要用在测量仪表,传感器管理,能量收集传感器节点,数据资料记录和穿戴电子.本文介绍了MSP430FR59xx系列主要特性,功能框图,以及MSP-EXP430FR5969 LaunchPad开发板主要特性,框图,电路图,材料清单和PCB设计图.

　　The MSP430™ ultra-low-power (ULP) FRAM platform combines uniquely embedded FRAM and a holistic ultra-low-power system architecture, allowing innovators to increase performance at lowered energy budgets. FRAM technology combines the speed, flexibility, and endurance of SRAM with the stability and reliability of flash at much lower power.

　　The MSP430 ULP FRAM portfolio consists of a diverse set of devices featuring FRAM, the ULP 16-bit MSP430 CPU, and intelligent peripherals targeted for various applications. The ULP architecture showcases seven low-power modes, optimized to achieve extended battery life in energy-challenged applications.

　　The Texas Instruments MSP430FR59xx family of ultra-low-power microcontrollers consists of several devices featuring different sets of peripherals. The architecture, combined with seven low-power modes is optimized to achieve extended battery life for example in portable measurement applications. The devices features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency.

　　The MSP430FR59xx devices are microcontroller configurations with up to five 16-bit timers, Comparator, universal serial communication interfaces (eUSCI) supporting UART, SPI, and I2C, hardware multiplier, AES accelerator, DMA, real-time clock module with alarm capabilities, up to 40 I/O pins, and an high performance 12-bit analog-to-digital converter (ADC).

　　The MSP430 CPU has a 16-bit RISC architecture that is highly transparent to the application. All operations, other than program-flow instructions, are performed as register operations in conjunction with seven addressing modes for source operand and four addressing modes for destination operand.

　　The CPU is integrated with 16 registers that provide reduced instruction execution time. The register-to register operation execution time is one cycle of the CPU clock.

　　Four of the registers, R0 to R3, are dedicated as program counter, stack pointer, status register, and constant generator, respectively. The remaining registers are general-purpose registers.Peripherals are connected to the CPU using data, address, and control buses, and can be handled with all instructions.

　　The instruction set consists of the original 51 instructions with three formats and seven address modes and additional instructions for the expanded address range. Each instruction can operate on word and byte data.
