　　TI公司的MSP430F599x系列是低功耗高性能铁电随机存储器(FRAM)微控制器(MCU),具有用于数字信号处理的独特的低功耗加速器(LEA),能提升ARM Cortex-M0+ MCU的性能40x,工作电压1.8 V- 3.6 V,主要用在智能电网,可穿戴电子,手持健康和健身设备,工厂自动化和控制,建筑物自动化.本文介绍了MSP430F599x系列主要特性,功能框图,以及LaunchPad开发套件MSP ‑‑EXP430FR5994主要特性,框图和电路图.

　　The MSP430F599x microcontrollers (MCUs) take low power and performance to the next level with the unique Low-Energy Accelerator (LEA) for digital signal processing. This accelerator delivers 40x the performance of ARM Cortex-M0+ MCUs to help developers efficiently process data using complex functions such as FFT, FIR, and matrix multiplication. Implementation requires no DSP expertise with a free optimized DSP Library available. Additionally, with up to 256KB of unified memory with FRAM, these devices offer more space for advanced applications and flexibility for effortless implementation of over-the-air firmware updates.

　　The MSP ultra-low-power (ULP) 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 nonvolatile behavior of Flash.

　　MSP430FR5994 LaunchPad开发套件MSP ‑‑EXP430FR5994

　　The MSP-EXP430FR5994 LaunchPad development kit is an easy-to-use evaluation module (EVM) for theMSP430FR5994 microcontroller (MCU). The LaunchPad development kit contains everything needed tostart developing on the ultra-low-power MSP430FRx FRAM microcontroller platform, including onboarddebug probe for programming, debugging and energy measurements. The board features onboard buttons

　　and LEDs for quick integration of a simple user interface, a microSD card port to interface with microSDcards, and a super capacitor (super cap) to enable stand-alone applications without an external powersupply.

　　The MSP430FR5994 MCU features 256KB of embedded FRAM (Ferroelectric Random Access Memory),a nonvolatile memory known for its ultra-low power, high endurance, and high speed write access. Thedevice also features 8 KB of SRAM, supports CPU speeds of up to 16 MHz and has integratedperipherals for communication, ADC, timers, AES encryption, low-energy accelerator (LEA) (a newhardware module for the FRAM family that is designed for fast, efficient, and low-power vector math), andmore–plenty to get you started in your development.

　　Rapid prototyping is simplified by the 40-pin BoosterPack™ plug-in module headers, which support a widerange of available BoosterPack modules. Quickly add features like wireless connectivity, graphicaldisplays, environmental sensing, and much more. Design your own BoosterPack plug-in module orchoose among many already available from TI and third-party developers.

　　Free software development tools are also available, such as the TI Eclipse-based Code ComposerStudio™ IDE (CCS) and the IAR Embedded Workbench® for MSP430™ IDE (EW430). Both of these IDEssupport EnergyTrace++™ technology for real-time power profiling and debugging when paired with theMSP430FR5994 LaunchPad kit.
