This puts it in the class of MCUs that can run a PID loop with sensor fusion without a separate DSP — the FPU handles the trig and matrix math in a few cycles. Program memory is 64 KB of Flash, paired with 24 KB of SRAM and a separate 2 KB EEPROM block for calibration constants or boot parameters that survive reprogramming.
Package and supply — board-level fit
Housed in a 64-LQFP with a 10x10 mm body and 0.5 mm pitch, it reflows on a standard lead-free profile. The internal oscillator starts up without a crystal — useful for cost-sensitive boards where the CAN or USB clock accuracy isn't critical.
The base product number TM4C1231 covers a density family, so if a future BOM needs more Flash the TM4C1233 variants are the natural step-up.
