The TM4C123GE6PZTR runs an ARM Cortex-M4F core at 80 MHz. The 128 KB Flash and 32K x 8 RAM support a single control algorithm plus a communications stack.
The peripheral set includes CAN, USB OTG, and multiple UART/SPI/I²C ports. The 22-channel 12-bit ADC covers multi-axis analog feedback.
Lifecycle status — plan your BOM accordingly
The TM4C123GE6PZTR is flagged as end-of-life (EOL) in the lifecycle record. That means the manufacturer's last-time-buy window has closed or is closing. For a production BOM, you are looking at surplus or broker-channel sourcing. If you need a guaranteed supply for a multi-year program, consider moving to a current Tiva C or TM4C129x part with a similar peripheral map — but verify pin compatibility on the 100-LQFP footprint before swapping.
