Funktionen

• 32-bit ARM® Cortex™-M4 80-MHz processor core with System Timer (SysTick), integrated Nested Vectored Interrupt Controller (NVIC), Wake-Up Interrupt Controller (WIC) with clock gating, Memory Protection Unit (MPU), IEEE754-compliant single-precision Floating-Point Unit (FPU), Embedded Trace Macro and Trace Port, System Control Block (SCB) and Thumb-2 instruction set

• On-chip memory, featuring 256 KB single-cycle Flash up to 40 MHz (a prefetch buffer improves performance above 40 MHz), 32 KB single-cycle SRAM; internal ROM loaded with TivaWare™ for C Series software; 2KB EEPROM

• Two Controller Area Network (CAN) modules, using CAN protocol version 2.0 part A/B and with bit rates up to 1 Mbps

• Universal Serial Bus (USB) controller with USB 2.0 full-speed (12 Mbps) and low-speed (1.5 Mbps) operation, 32 endpoints, and USB OTG/Host/Device mode

• Advanced serial integration, featuring: eight UARTs with IrDA, 9-bit, and ISO 7816 support (one UART with modem status and modem flow control); four Synchronous Serial Interface (SSI) modules, supporting operation for Freescale SPI, MICROWIRE, or Texas Instruments synchronous serial interfaces; six Inter-Integrated Circuit (I²C) modules, providing Standard (100 Kbps) and Fast (400 Kbps) transmission and support for sending and receiving data as either a master or a slave

• ARM PrimeCell® 32-channel configurable μDMA controller, providing a way to offload data transfer tasks from the Cortex™-M4 processor, allowing for more efficient use of the processor and the available bus bandwidth

• Analog support, featuring: two 12-bit Analog-to-Digital Converters (ADC) with 24 analog input channels and a sample rate of one million samples/second; three analog comparators; 16 digital comparators; on-chip voltage regulator

• Advanced motion control, featuring: eight Pulse Width Modulation (PWM) generator blocks, each with one 16-bit counter, two PWM comparators, a PWM signal generator, a dead-band generator, and an interrupt/ADC-trigger selector; eight PWM fault inputs to promote low-latency shutdown; two Quadrature Encoder Interface (QEI) modules, with position integrator to track encoder position and velocity capture using built-in timer

• Two ARM FiRM-compliant watchdog timers; six 32-bit general-purpose timers (up to twelve 16-bit); six wide 64-bit general-purpose timers (up to twelve 32-bit); 12 16/32-bit and 12 32/64-bit Capture Compare PWM (CCP) pins

• Up to 120 GPIOs (depending on configuration), with programmable control for GPIO interrupts and pad configuration, and highly flexible pin muxing

• Lower-power battery-backed Hibernation module with Real-Time Clock

• Multiple clock sources for microcontroller system clock: Precision Oscillator (PIOSC), Main Oscillator (MOSC), 32.768-kHz external oscillator for the Hibernation Module, and Internal 30-kHz Oscillator

• Full-featured debug solution with debug access via JTAG and Serial Wire interfaces, and IEEE 1149.1-1990 compliant Test Access Port (TAP) controller

• Industrial-range (-40°C to 85°C) RoHS-compliant 157-ball BGA
