Texas Instruments Tiva™ Series MCUs

Texas Instruments Tiva™ C Series Microcontrollers are the first ARM Cortex™-M4 MCUs to be implemented on TI's proprietary 65-nm process technology. Tiva C Series devices increase connectivity integration without sacrificing price, performance, or power consumption. Every TI Tiva 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 1.6μA. With up to 40 PWM outputs, a generous number of serial communication peripherals, USB OTG, and two CAN controllers, the Tiva C Series provides an excellent baseline for home, building, and industrial applications.


Key Features
  • Floating-point capable
  • 256 KB Flash, 32 KB SRAM
  • Two 12-bit, 24-channel, 1-MSPS ADCs
  • Optional full-speed USB 2.0 with device, host, and OTG
  • Advanced motion control capability—up to 40 PWM outputs and two quadrature encoder interfaces
  • Generous serial communication options available:
    • Eight UARTs
    • Six I2C
    • Four SPI / SSI
  • Low-power modes, including power-saving hibernate
  • 64-LQFP, 100-LQFP, 144-LQFP, and 157-BGA packages
Applications
  • Automation & Process Control
  • Consumer & Portable Electronics
  • Human Machine Interface
  • Industrial
  • Lighting
  • Sensor Hub

Texas Instruments TM4C123x Tiva™ C Series MCUs provide a broad portfolio of connected Cortex™-M4F microcontrollers. Designers who migrate to the Tiva C Series MCUs benefit from a balance between the floating-point performance needed to create highly responsive mixed-signal applications and the lowpower architecture required to enable increasingly aggressive power budgets. Tiva C Series MCUs are supported by TivaWare™ for C Series software, designed specifically for those customers who want to get started easily, write production-ready code quickly, and minimize their overall cost of software ownership. TM4C123x MCUs offer 12-bit ADC accuracy achievable at the full 1 MSPS rating without any hardware averaging, eliminating performance tradeoffs. These are the first ARM Cortex-M MCU in advanced 65-nm process technology, providing the right balance between higher performance and low power consumption.

Texas Instruments Tiva C Series MCUs

Cortex-M4

Tiva is the new name for TI's low-end Cortex-M series. Tiva C Series TM4C123x MCUs were formerly known as Stellaris® LM4F MCUs. Tiva MCUs are built upon common software libraries to help ease migration across future Tiva ARM MCUs for a wide range of connected applications.


Cortex-M3

Stellaris Cortex-M3 MCUs have been phased out and are no longer recommended for new designs. TI still offers C2000 Piccolo Cortex-M3 devices.
