80 MHz Cortex-M4F with floating-point unit
The 256 KB on-chip Flash and 32 KB SRAM support moderate firmware images and real-time data buffers without external memory. The 2 KB EEPROM holds calibration constants or configuration parameters that survive power loss — useful for field-set parameters in motor drives or HMI panels.
The 49 GPIOs include a 12-channel 12-bit ADC for analog sensor inputs, plus CAN, I²C, SPI, SSI, UART, and IrDA interfaces — enough to bridge a CANopen fieldbus to a local sensor array or drive a small TFT display over SPI.
Lifecycle: end-of-life active — plan your last-time buy
The TM4C123AH6PMI has an active product status per the manufacturer, but the lifecycle stage is flagged as EOL hot. For production BOMs, treat this part as a last-time-buy candidate.
