Texas Instruments introduced the Tiva ARM microcontrollers. The Tiva C Series TM4C123x ARM Cortex-M4 MCU is the first device of the new platform. It is the first Cortex-M-based MCUs to be built on 65 nanometer flash process technology. The Tiva C Series TM4C123x MCUs, formerly known as Stellaris LM4F MCUs, are in production now. Pricing for the TI Tiva ARM microcontroller starts at $2.15 at 10K quantities. They are ideal for home, building and industrial automation.
The TI C Series MCU integrates a floating-point core and high-performance analog-to-digital converters while still providing low-power modes that consume as little 1.6 µA. The Tiva ARM microcontrollers feature up to 40 PWM outputs, serial communication peripherals, USB OTG, and two CAN controllers.
The peripheral library and in-system programming utilities are included in ROM on every Tiva C Series MCU. TivaWare for C Series delivers USB, CAN, graphics, and sensor application libraries so that customers can focus their energy on building applications instead of programming their connectivity peripherals.
Texas Instruments Tiva C Series MCUs Features
- Differentiate applications using targeted performance headroom with ARM Cortex-M4 floating-point core, operating at up to 80 MHz
- Support mixed-signal applications with high-performance analog integration
- 2 high-performance 12-bit analog-to-digital converters (ADCs) and 3 comparators
- Eliminate performance tradeoffs with 12-bit ADC accuracy, achievable at the full 1 MSPS rating without any hardware averaging
- Communicate with on-chip connectivity options, including USB (host, device and On-The-Go), UARTs, I2C, SSI/SPI and CAN
- Support high-endurance non-volatile storage of user interface or configuration parameters to reduce system cost using integrated EEPROM
- Enable longer battery life and support constrained power budgets with low-power — standby currents as low as 1.6 µA
- Address varying applications needs with device options up to 256KB flash and 32KB SRAM
