Tiva^™ TM4C1230D5PM Microcontroller
2 The Cortex-M4F Processor
The ARM® Cortex™-M4F processor provides a high-performance, low-cost platform that meets the
system requirements of minimal memory implementation, reduced pin count, and low power
consumption, while delivering outstanding computational performance and exceptional system
response to interrupts. Features include:
■ 32-bit ARM^® Cortex^™-M4F architecture optimized for small-footprint embedded applications
■ 80-MHz operation; 100 DMIPS performance
■ Outstanding processing performance combined with fast interrupt handling
■ Thumb-2 mixed 16-/32-bit instruction set delivers the high performance expected of a 32-bit
ARM core in a compact memory size usually associated with 8- and 16-bit devices, typically in
the range of a few kilobytes of memory for microcontroller-class applications
– Single-cycle multiply instruction and hardware divide
– Atomic bit manipulation (bit-banding), delivering maximum memory utilization and streamlined
peripheral control
– Unaligned data access, enabling data to be efficiently packed into memory
■ IEEE754-compliant single-precision Floating-Point Unit (FPU)
■ 16-bit SIMD vector processing unit
■ Fast code execution permits slower processor clock or increases sleep mode time
■ Harvard architecture characterized by separate buses for instruction and data
■ Efficient processor core, system and memories
■ Hardware division and fast digital-signal-processing orientated multiply accumulate
■ Saturating arithmetic for signal processing
■ Deterministic, high-performance interrupt handling for time-critical applications
■ Memory protection unit (MPU) to provide a privileged mode for protected operating system
functionality
■ Enhanced system debug with extensive breakpoint and trace capabilities
■ Serial Wire Debug and Serial Wire Trace reduce the number of pins required for debugging and
tracing
■ Migration from the ARM7^™ processor family for better performance and power efficiency
■ Optimized for single-cycle Flash memory usage up to specific frequencies; see “Internal
Memory” on page 446 for more information.
■ Ultra-low power consumption with integrated sleep modes
