The TM4C123GH6PGET7 is a 32-bit ARM Cortex-M4F MCU from TI's Tiva C series, clocked at 80 MHz with 256 KB Flash and 32 KB RAM. It integrates a floating-point unit, USB OTG, CAN, and multiple serial interfaces — suited for industrial control, motor drives, and automotive-adjacent applications where a single-chip mixed-signal controller is needed.
80 MHz Cortex-M4F — what it buys you
80 MHz on a single-cycle multiply-accumulate core with FPU handles a PID loop with headroom for sensor filtering and comms stack overhead.
256 KB Flash + 32 KB RAM — firmware fit
256 KB Flash (256K x 8) holds a FreeRTOS image with USB stack, CANopen, and a modest application layer. 32 KB RAM covers a few large buffers.
Lifecycle — EOL notice active
This part carries an end-of-life (EOL) status. The last-time-buy window is open; once it closes, supply will shift to surplus and broker channels. Buyers should secure lifetime-requirement quantities now or evaluate a pin-compatible migration path within the Tiva C family.
