What this Tiva C MCU brings to the board
The TM4C123GE6PZIR is a 32-bit ARM Cortex-M4F microcontroller from the Tiva C series, clocked at 80 MHz with 128 KB of Flash and 32K x 8 of RAM. It packs 69 I/O lines and a 22-channel 12-bit ADC, plus CAN, USB OTG, and multiple serial interfaces.
80 MHz on a Cortex-M4F with single-cycle MAC handles a PID loop and a Modbus stack. The 12-bit ADC on 22 channels samples analog sensors while the CAN frame arbitrates.
The TM4C123GE6PZIR carries an EOL hot lifecycle status. The manufacturer has announced end-of-life; last-time-buy windows are closing or closed.
