摘要:TI公司的MSP430FR5969是超低功耗(ULP) FRAM平台,集成了嵌入FRAM和超低功耗系统16位RISC架构,工作频率16MHz,工作电压1.8V-3.6V,工作模式功耗100 µA/MHz,关断功耗0.02 µA,主要用在计量,传感器管理,数据采集,可穿戴电子和能量收获传感器节点.本文介绍了MSP430FR5969主要特性,功能框图,以及TIDA-00373智能照明参考设计主要特性,框图,电路图和材料清单.
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.
