ARM Cortex-M4 microcontrollers extend TI’s connected-device-controller offering
The first devices in the new platform – Tiva C Series TM4C123x ARM Cortex-M4 MCUs – are the first Cortex-M-based MCUs to be built on 65-nm flash process technology, enabling higher speeds, larger memory and lower power. Tiva MCUs are built upon common software libraries to help ease migration across future Tiva ARM MCUs for a wide range of connected applications. The MCUs target varied applications with ARM Cortex-M4 floating-point core, operating at up to 80 MHz; they support mixed-signal applications with high-performance analogue integration – two high-performance 12-bit analogue-to-digital converters (ADCs) and three comparators. They eliminate performance tradeoffs with 12-bit ADC accuracy, achievable at the full 1 MSPS rating without any hardware averaging. The chips communicate with on-chip connectivity options, including USB (host, device and On-The-Go), UARTs, I2C, SSI/SPI and CAN. TIVA processors support high-endurance non-volatile storage of user interface or configuration parameters to reduce system cost using integrated EEPROM. Longer battery life and constrained power budgets are addressed with low-power standby currents as low as 1.6 µA. Memory options include up to 256 kB flash and 32 kB SRAM.
TivaWare for C Series MCUs provide “no-OS” software development, enabling developers to get started quickly. 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). TI’s software is complemented by a complete Design Network, which includes IAR Networks.
The Tiva C Series TM4C123x MCUs begin at $2.15 (10,000) The $12.99 USD EK-TM4C123GXL Tiva ARM C Series LaunchPad is available now.
