That FPU matters for sensor fusion, motor-control FOC, or any loop where integer math chews through MIPS — the single-precision multiply-accumulate runs in one cycle, not a software library call. 256 KB of Flash and 32 KB of RAM give the firmware room for a real-time OS and a moderate data buffer; the 2 KB EEPROM holds calibration or boot-config values without external storage. ## Lifecycle — EOL hot, sourcing to order","metaTitle":"TI TM4C123BH6ZRBIR Tiva C ARM Cortex-M4F MCU, 80 MHz","metaDescription":"Texas Instruments TM4C123BH6ZRBIR Tiva™ C Series 32-bit ARM Cortex-M4F MCU. 80 MHz, 256 KB Flash, 32 KB RAM, 120 I/O, 157-VFBGA.
