80 MHz Cortex-M4F with FPU — what that means on the bench
The TM4C1230E6PMT is a Texas Instruments Tiva™ C series 32-bit ARM Cortex-M4F microcontroller running at 80 MHz. That core includes a single-precision floating-point unit, so PID loops, sensor fusion math, and FFTs run in hardware rather than soft-emulated. The 2 KB EEPROM is a practical addition: calibration coefficients or node-ID settings survive a power cycle without external serial EEPROM.
The 12-bit ADC with 12 channels handles analog feedback from current shunts or thermistors.
Lifecycle reality — check the LTB window
Texas Instruments lists this part as Active, but the lifecycle record flags it as EOL hot. Confirm the last-time-buy end date with TI and budget for a one-time buy covering your production horizon.
