The 43 GPIOs route through a 64-LQFP (10x10 mm) package, a common footprint for panel-mount and industrial PCBs. ## 80 MHz Cortex-M4F — what the clock buys you At 80 MHz with a hardware FPU, this core handles single-precision floating-point math without software emulation overhead. The 128 KB Flash is the mid-density tier in the TM4C1237 family. The 12-bit ADC with 12 channels covers analog inputs like thermocouple or potentiometer feedback. Rated for -40 to 85 °C ambient, this MCU operates from a 1.08 V to 3.63 V supply range. The TM4C1237E6PMIR is flagged as EOL hot — end-of-life active.","metaTitle":"TM4C1237E6PMIR Tiva C ARM Cortex-M4F MCU, 80MHz, 128KB Flash","metaDescription":"TM4C1237E6PMIR Tiva C series 32-bit ARM Cortex-M4F MCU. 80MHz speed, 128KB Flash, 32K x 8 RAM, 2K x 8 EEPROM.
