Texas Instruments TM4C123x Tiva™ C 系列 MCU

Texas Instruments TM4C123x Tiva™ C 系列 MCU 为您提供了丰富的连接 Cortex™-M4F 微处理器系列产品。转向 Tiva C 系列 MCU 的设计人员可从创建高度响应的混合信号应用所需的浮点运算性能，与实现愈发具有挑战性的功率分配所需的低功耗架构的平衡中获益。Tiva C 系列 MCU 兼容TivaWare™ (C系列)软件，特别针对希望入门简单、能快速编写生产就绪代码并最小化软件总成本的客户而设计。TM4C123x MCU 精度与12位 ADC 相当(满 1MSPS 速率下，无硬件平均)，且性能不受影响。该系列器件是最先采用了先进的65nm处理技术的 ARM Cortex-M MCU，可对高性能和低功耗进行正确平衡。

The TM4C123x MCUs offer 12-bit ADC accuracy achievable at the full 1 MSPS rating without hardware averaging, eliminating performance tradeoffs. These are the first ARM Cortex-M MCU in advanced 65-nm process technology, providing the right balance between higher performance and low power consumption.
