That FPU matters if you're running PID loops or sensor fusion without a math coprocessor — single-cycle MAC and divide instructions keep the control loop tight. The 64 KB Flash and 24 KB RAM are enough for a modest HMI or a CAN gateway node; the 2 KB EEPROM saves you an external serial EEPROM for calibration constants or boot counters.

Product details
Frequently asked questions
What is the closest pin-compatible alternative to TM4C1230D5PMI?
The TM4C1231D5PMI (128 KB Flash) is pin-compatible within the Tiva C family — same package, same peripherals, same 80 MHz core. Firmware migration requires only a linker script change if you use the extra Flash.
What is the speed of TM4C1230D5PMI?
80 MHz core clock on the ARM Cortex-M4F, with single-cycle multiply and hardware divide.
What compliance documentation is available for TM4C1230D5PMI?
TI provides RoHS and REACH declarations for this part. The 64-LQFP package is lead-free and compatible with standard reflow profiles. No UL or IEC certification is listed for this MCU — those are typically system-level, not component-level.
