80 MHz on a Cortex-M4F with single-cycle MAC and FPU means this part handles a PID loop at several kHz while still servicing CAN messages and a USB stack. The 32 KB RAM is tight for heavy buffering — plan your DMA buffers and stack usage early. The 2 KB EEPROM saves an external serial EEPROM for calibration constants or boot counters.
For BOM freeze planning, the base product number TM4C1236 covers a family of Flash and RAM density options in the same 64-LQFP footprint — if a future spin needs more memory, a pin-compatible sibling exists without a board respin.
