It packs 128 KB of Flash program memory, 32K x 8 of SRAM, and 2K x 8 of EEPROM — enough for a moderate control loop or a communication gateway firmware image. 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.
