Product details

The TM4C123BH6PGEI7 is a Texas Instruments Tiva C series microcontroller built around an ARM Cortex-M4F core with a single-precision floating-point unit, clocked at 80 MHz.

Peripheral set — CAN, QEI, and the 24-channel ADC

The quadrature encoder interface (QEI) is purpose-built for reading incremental encoder channels on a servo or conveyor axis without bit-banging GPIO. On the analog side, 24 multiplexed 12-bit ADC channels cover multi-sensor acquisition (thermocouples, current shunts, pressure transducers) without an external mux.

Frequently asked questions

What is the closest pin-compatible alternative to TM4C123BH6PGEI7?

No official pin-compatible successor is listed for this specific variant. The Tiva C family includes active 144-LQFP devices with similar peripheral sets, but any migration requires verifying Flash/RAM sizing and checking for minor peripheral differences — plan for a qualification cycle.

What is TM4C123BH6PGEI7's listed speed?

The core runs at 80 MHz. That clock rate, combined with the single-precision FPU, delivers enough throughput for real-time motor control loops and sensor fusion without external DSP.
