Cortex-M4 controller integates Ethernet MAC+PHY as gateway to the Internet of Things
The Tiva TM4C129x MCUs are aimed at advanced connected applications, such as home/building automation gateways, connected human-machine interface (HMI), networked sensor gateways, security access systems, programmable logic controllers and many others.
The devices include 10/100 Ethernet MAC+PHY with advanced line diagnostics for smart identification of cabling issues and integrated CAN and USB provide high-speed connectivity, allowing the creation of seamless gateway solutions. Control outputs manage multiple events, such as 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, as well as advanced pulse-width modulation (PWM) outputs. Application memory needs are met with pin for pin compatibility across the TM4C129x portfolio from 256 KB of integrated SRAM and 6KB EEPROM to support greater functionality, along with a scalable 512KB to 1 MB Flash memory offering to support 100,000 program cycles for extended in-field updates and reliable operation.
The devices add data and tamper protection to applications and reduce processing overhead with the hardware acceleration of key encryption/decryption functions and cyclic redundancy check (CRC). Monitor and log external events and invoke corresponding actions to further secure critical data using tamper protection inputs and their associated capabilities.
Developers can start evaluating Tiva TM4C129x MCUs with the available Tiva DK-TM4C129x Connected Development Kit, which utilizes the on-chip Ethernet MAC+PHY. The kit also includes two ports for BoosterPack connectivity, making this development kit the first to directly connect the TI MCU LaunchPad ecosystem to the Internet. Combined with this leading-edge development hardware, its fully integrated, unmatched software platform provides the most powerful development ecosystem of its kind. The Tiva TM4C129x MCUs are built upon the TivaWare software foundation with more than 50 accompanying software application examples, which accelerate programming time and allow developers to concentrate on delivering differentiated products to market more quickly. A broad ecosystem offers a variety of development options, including TI’s Eclipse-based Code Composer Studio integrated development environment (IDE), along with a myriad of third-party tools and software.
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 USD through the TI estore and licensed TI distributors.
