Tiva C Cortex-M4F for industrial control and connectivity
It carries 256 KB of Flash program memory and 32K x 8 of SRAM, plus 2K x 8 EEPROM for parameter storage without external EEPROM. The 105 general-purpose I/O pins and 24-channel 12-bit ADC give it the I/O count and analog front-end for multi-sensor industrial control panels, motor drives, and human-machine interfaces.
80 MHz Cortex-M4F — what the core speed buys you
The 80 MHz ARM Cortex-M4F with single-cycle DSP instructions and a hardware FPU handles real-time control loops — PID, sensor fusion, FOC for brushless DC motors — without a separate DSP coprocessor. The floating-point unit accelerates trigonometric and matrix math for encoder interpolation and coordinate transforms. For protocol stacks, the 80 MHz clock keeps CAN and USB packet processing within the interrupt service time budget, leaving headroom for the application loop.
Memory sizing for firmware and data buffers
256 KB Flash and 32K x 8 SRAM support a single firmware image with a bootloader and RTOS. The 2K x 8 EEPROM stores calibration data that survives firmware updates.
Supply voltage spans 1.08 V to 3.63 V, with on-chip brown-out detect and POR.
