The floating-point unit handles single-cycle MAC operations, so sensor fusion, PID loops, and FFTs run in hardware rather than software-emulated. 128 KB of Flash and 32 KB of SRAM are enough for a moderate application with a bootloader and a few hundred lines of control code; the 2 KB EEPROM holds calibration constants or fault logs without wearing the Flash. ## Connectivity and I/O — CAN, USB OTG, and the serial mix","metaTitle":"TM4C1237E6PZIR Tiva C MCU, 80MHz Cortex-M4F, 128KB Flash","metaDescription":"Texas Instruments TM4C1237E6PZIR 32-bit ARM Cortex-M4F MCU, 80MHz, 128KB Flash, 32KB SRAM, CAN/USB OTG, -40 to 85°C.
