10月30日消息，据外媒Electronicsweekly报道，德州仪器 (TI) 宣布推出了基于ARM Cortex-M4 平台的单片机Tiva TM4C129x，集成了以太网MAC和PHY特点，用以支持互联网连接，主要应用于工业控制领域。

Tiva TM4C129x 配备256K字节集成SRAM、6K字节EEPROM，可扩展的512K字节 1MB闪存。这个级别的内存将支持人机界面功能的终端液晶显示技术的开发。

TIVA DK-TM4C129x 连接开发工具包，配有两个BoosterPack连接端口；开发套件TI MCU LaunchPad生态系统可以直接连接到互联网。集成开发生态系统包括德州仪器 (TI)嵌入式处理器系列的集成开发环境 (IDE) Code Composer Studio (CCStudio)、以及第三方工具和软件支持。

直观的 IDE 提供了单个用户界面，可帮助您完成应用开发流程的每个步骤。 借助于精密的高效工具，用户能够利用熟悉的工具和界面快速上手并将功能添加至他们的应用。CCStudio 包含一整套用于开发和调试嵌入式应用的工具。 它包含适用于每个 TI 器件系列的编译器、源码编辑器、项目构建环境、调试器、描述器、仿真器、实时操作系统以及多种其他功能。

此前，德州仪器提供了TMS370和MSP430两大系列通用单片机。TMS370系列单片机是8位CMOS单片机，具有多种存储模式、多种外围接口模式，适用于复杂的实时控制场合；MSP430系列单片机是一种超低功耗、功能集成度较高的16位低功耗单片机，特别适用于要求功耗低的场合。

单片机主要应用于照明、传感、运动、显示器和开关。现代人类生活中所用的手机、电话、计算器、家用电器、电子玩具、掌上电脑以及鼠标等电子产品中都含有单片机。由运算器、控制器、存储器、输入输出设备构成，相当于一个微型的计算机（最小系统），和计算机相比，单片机缺少了外围设备。

供货部分，TIVA TM4C129x单片机为TIVA C系列产品组合新添了20台设备。TIVA TM4C129x 单片机每10K起售价是6.24美元。TIVA DK-TM4C129x 连接开发套件单价是199美元。CC3000 BoosterPack包括无线网络连接。TI 公司现提供TivaWare软件与Code Composer Studio V.5 IDE 嵌入式处理器系列下载。(元器件交易网龙燕 编译)

A feature of the Tiva TM4C129x range of MCUs is the 256kbyte of integrated SRAM and 6kbyte EEPROM, along 

with a scalable 512kbyte to 1MB flash memory.

This level of memory will support the development of LCD terminal displays with human-machine interface capabilities.

There are also data protection fumctions including tamper protection provided by hardware acceleration of key encryption/decryption functions and cyclic redundancy check (CRC).

There is development support with the Tiva DK-TM4C129x Connected Development Kit which includes two ports for BoosterPack connectivity, making this development kit the first of its class to directly connect the TI MCU LaunchPad ecosystem to the Internet.

The development ecosystem includes TI’s Eclipse-based Code Composer Studio integrated development environment (IDE), along with third-party tools and software.

Typical controller applications will include lighting, sensing, motion, display and switching, using sensor aggregation capabilities with 10 I2C ports, two fast, accurate 12-bit analog-to-digital converters (ADCs), two quadrature encoder inputs, three on-chip comparators, external peripheral interface.

Tiva TM4C129x MCUs add an additional 20 devices to the Tiva C Series portfolio and are priced starting at $6.24 per 10K. The Tiva DK-TM4C129x Connected Development Kit is available for $199.

The CC3000 BoosterPack includes Wi-Fi. TivaWare software and TI’s Code Composer Studio v.5 IDE are available for download.
