That FPU cuts the cycle count on PID loops and sensor fusion math — no software emulation overhead. The 49 I/O lines in a 64-LQFP package keep board routing manageable for a 4-layer design.
This part is flagged EOL hot, meaning Texas Instruments has issued an end-of-life notice. The official status is active, but the EOL hot flag tells procurement to treat it as a last-time-buy candidate.
No official successor is listed. The TM4C123GH6PM is a pin-compatible alternative in the same 64-LQFP package with the same core and memory, adding USB OTG. Verify USB pin allocation before substituting.
Yes — this part is part of the Tiva C series and is supported by TI's TivaWare software library, including peripheral driver libraries and the USB stack.
The pinout follows the standard 64-LQFP Tiva C mapping. Refer to the TM4C1232H6PM datasheet for the full pin assignment table — the base product number is TM4C1232.
Both are 80 MHz Cortex-M4F MCUs in 64-LQFP with 256 KB Flash and 32 KB RAM. The GH6PM adds a USB OTG controller; the TM4C1232H6PMIR omits OTG, which may simplify the USB stack if host-mode is not needed. Pin compatibility is high but verify the USB pins.
