Texas Instruments Announces Tiva Cortex M4 MCUs and $12.99 LaunchPad Evaluation Kit

Texas Instruments has just announced the Tiva ARM MCU platform, and specifically the Tiva C Series TM4C123x ARM Cortex-M4 MCUs, which are the first Cortex-M MCUs to be built on 65 nanometer flash process technology. The Tiva C Series TM4C123x MCUs, formerly known as Stellaris LM4F MCUs, are available now and target home, building and industrial automation.


Key features and benefits of Tiva C Series MCUs:

  • MCU Core – ARM Cortex-M4 floating-point core, operating at up to 80 MHz.
  • Mixed-signal applications with high-performance analog integration – 2×12-bit ADC and 3 comparators.12-bit ADC accuracy is achievable at the full 1 MSPS rating without any hardware averaging.
  • On-chip connectivity options – USB (host, device and On-The-Go), UARTs, I2C, SSI/SPI, CAN, etc..
  • Non-volatile storage of user interface or configuration parameters to reduce system cost – Thanks to integrated EEPROM.
  • Low power –  Standby currents as low as 1.6 uA.
  • Large choice of MCU RAM and storage sizes – Up to 256KB flash and 32KB SRAM.

On the software side, TI-RTOS, a real-time operating system, is available to all TI MCUS, and for applications that do not need an operating system, TivaWare for C Series MCUs is a free toolkit allowing “no OS” software development. Support is available through FAE or via E2E online community. As with its other MCUs, Texas Instruments also provides a low cost evaluation kit.

EK-TM4C132G LaunchPad includes:

  • A TM4C123G LaunchPad Evaluation board with TM4C123GH6PM MCU (256KB Flash / 32KB SRAM)
  • On-board In-Circuit Debug Interface (ICDI)
  • USB Micro-B plug to USB-A plug cable
  • Preloaded RGB quickstart application
  • ReadMe First quick-start guide

The board is compatible with TI’s BoosterPacks should you need to extend the capabilities of the board.

The Tiva C Series TM4C123x MCUs are available now and price starts at 2.15 USD in 10K quantities. The LaunchPad kit (EK-TM4C123GXL) can be purchased on TI e-Store for $12.99 now, but you’ll need to wait 8 to 10 weeks before delivery. TI also announced Tiva C Series devices with Ethernet capabilities will be available in in the near future. Further information can be found in Tiva C Series page.

  1. A quick comparison Stellaris Launchpad vs this would be fantastic 😉

    Apart from the 65 nanometer flash, I see no differences.

  2. I feel a bit disappointed with TI. They released Stellaris and were selling it for like half year as “normal” product. However Stellaris was just buggy “alpha” version of what is coming now.

    “DO NOT USE EEPROM” – ridiculous!!

  3. they were advertising Stellaris as having “Stellaris LM4F120” processor and what they were shipping was LX (experimental) version

  4. I am using the Stellaris in a current product because it had all the right features at the right price.
    On eof the features was the built-in Ethernet controller. To this date TI did not release a TIVA with Ethernet!
    The Hercules line is the only one with built-in Ethernet so far. But those controllers start at $15 !!!
    I am beginning to see why some people prefer Atmel; they keep their products running much, much longer and when they replace it, they come up with REAL alternatives…
    Step it up TI!
