原标题:大联大联合上海南潮推出基于TI TM4C1294NCPDT光伏电站监控运营解决方案
致力于亚太地区市场的领先半导体元器件分销商---大联大控股宣布,其旗下世平联合上海南潮信息科技推出基于TI TM4C1294NCPDT光伏电站监控运营解决方案。
描述
Tiva™ C Series microcontrollers integrate a large variety of rich communication features to enable a new class of highly connected designs with the ability to allow critical, real-time control between performance and power. The microcontrollers feature integrated communication peripherals along with other high-performance analog and digital functions to offer a strong foundation for many different target uses, spanning from human machine interface to networked system management controllers.
In addition, Tiva™ C Series microcontrollers offer the advantages of ARM's widely available development tools, System-on-Chip (SoC) infrastructure, and a large user community. Additionally, these microcontrollers use ARM's Thumb®-compatible Thumb-2 instruction set to reduce memory requirements and, thereby, cost. Finally, the TM4C1294NCPDT microcontroller is code-compatible to all members of the extensive Tiva™ C Series, providing flexibility to fit precise needs.
Texas Instruments offers a complete solution to get to market quickly, with evaluation and development boards, white papers and application notes, an easy-to-use peripheral driver library, and a strong support, sales, and distributor network.
