Texas Instruments (TI) claims that its new Tiva TM4C129x MCUs are the industry’s first ARM Cortex-M4-based MCUs with Ethernet MAC+PHY, enabling customers to create a new class of highly connected products that bridge the cloud and amplify the ever-growing Internet of Things (IoT). The new MCUs offer an unprecedented number of simultaneous connectivity options, as well as on-chip data protection and LCD controller to save significant board space and enable connected advanced applications such as home/building automation gateways, connected human-machine interface (HMI), networked sensor gateways, security access systems, programmable logic controllers and many others.
Developers can start evaluating Tiva TM4C129x MCUs with the Tiva DK-TM4C129XConnected 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 of its class to directly connect the TI MCU LaunchPad ecosystem to the Internet. Combined with leading-edge development hardware, its fully integrated software platform provides a powerful development ecosystem. The new 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.
- Connect to and communicate with products and services with 10/100 Ethernet MAC+PHY with advanced line diagnostics for smart identification of cabling issues. Integrated CAN and USB provide high-speed connectivity, allowing the creation of seamless gateway solutions.
- Control outputs and 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.
- Address varying application memory needs with pin for pin compatibility across the TM4C129x portfolio. With 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.
- 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.
