The Tiva platform is aimed at connected devices with easy-to-use development tools, software, training and support to further ease design and development. TivaWare for C Series MCUs provide “no-OS” software development, enabling even novice developers to get started quickly.
The first devices in the new platform – the Tiva C Series TM4C123x ARM Cortex-M4 MCUs – were the first Cortex-M-based MCUs to be built on 65 nanometer flash process technology as the Stellaris LM4F MCUs and are in production today for home, building and industrial automation. Tiva MCUs are built upon common software libraries to help ease migration across future Tiva ARM MCUs for a wide range of connected applications.
“We are excited to introduce our Tiva C Series MCUs because they truly are unique to the market. Tiva C Series MCUs combine TI’s on-chip, high-performance analog, robust software ecosystem and system expertise in connected applications,” said Scott Roller, vice president, MCU, TI. “Tiva C Series MCUs, along with our innovative low-power MSP, real-time control C2000 and safety MCU platforms enable our customers to choose the perfect MCU to meet their design needs.”
The Tiva MCUs operate at up to 80 MHz and support mixed-signal applications with high-performance analog integration with two high-performance 12-bit analog-to-digital converters (ADCs) and three comparators. These eliminate performance tradeoffs with 12-bit ADC accuracy, achievable at the full 1 MSPS rating without any hardware averaging. The on-chip connectivity options include USB (host, device and On-The-Go), UARTs, I2C, SSI/SPI and CAN and they support high-endurance non-volatile storage of user interface or configuration parameters to reduce system cost using integrated EEPROM. Standby currents are as low as 1.6µA and the devices address varying applications needs with device options up to 256KB flash and 32KB SRAM.
TI-RTOS, a real-time operating system unifies development among all TI MCUs to help designers easily transition devices while keeping code investments and is compatible with latest version of Code Composer Studio v.5 integrated development environment (IDE).
The Tiva C Series TM4C123x MCUs begin at $2.15 USD at 10K quantities. The $12.99 USD EK-TM4C123GXL Tiva ARM C Series LaunchPad is available for purchase now. Future Tiva C Series devices with Ethernet are forthcoming.
