80 MHz Cortex-M4F with FPU — what the core speed buys you
The TM4C1233H6PZI7 runs an ARM Cortex-M4F with single-precision floating-point unit at 80 MHz. The 32-bit core with hardware divide and single-cycle MAC handles FFT or PID math.
Memory map: 256 KB Flash, 32 KB SRAM, 2 KB EEPROM
The 32 KB SRAM (organized as 32K x 8) provides working space for data buffers and stack; the 2 KB EEPROM holds calibration constants, node IDs, or fault logs that survive power cycles without writing to Flash. No external EEPROM needed for parameter storage.
Analog and connectivity: 22-channel 12-bit ADC, CAN, USB
22 analog inputs with 12-bit resolution cover multi-sensor acquisition — thermocouple, current shunt, or potentiometer feedback on a motor drive. The CAN 2.0 A/B controller handles industrial fieldbus or vehicle networks; the USB 2.0 OTG interface supports device or host mode for data logging or firmware updates. Additional I²C, SPI, SSI, UART, and IrDA ports give flexibility for peripheral expansion without glue logic.
