That FPU matters if you are doing sensor fusion, motor-control PID loops, or any math that would otherwise eat cycles in software. The 256 KB Flash and 32K x 8 RAM give you room for a real-time control stack plus a communication protocol like CAN or USB — the connectivity list includes CANbus, I²C, SPI, SSI, and UART/USART. 105 I/O in a 144-LQFP package means you can route a fair amount of parallel interface or discrete sensing without a CPLD. ## Lifecycle — EOL hot, sourced through independent channels ## Industrial temperature grade — -40 to 85 °C The internal oscillator and brown-out detect keep it running through supply dips without an external supervisor.","metaTitle":"TM4C1231H6PGEI Tiva C ARM Cortex-M4F MCU, 80 MHz, 256 KB Flash","metaDescription":"TM4C1231H6PGEI Tiva C series 32-bit ARM Cortex-M4F MCU, 80 MHz, 256 KB Flash, 32K x 8 RAM, 144-LQFP, -40 to 85 °C.
