Product details

That FPU matters if you are doing real-time motor-current transforms or sensor fusion without a separate DSP — the hardware divide and MAC instructions keep the loop jitter under a few microseconds. 256 KB of Flash and 32K x 8 of RAM give enough room for a Modbus TCP stack plus a 22-channel 12-bit ADC scan, all on a 100-LQFP footprint.

Connectivity and I/O — fieldbus-ready

With CAN, I²C, SPI, SSI, UART, and QEI on the peripheral list, this part can bridge a CANopen motor drive to a UART-based HMI panel without an external protocol converter.

Lifecycle and sourcing — EOL hot, plan the bridge

Supply range is 1.08 V to 3.63 V.

Frequently asked questions

What is the closest pin-compatible alternative to TM4C123BH6PZI7R?

Any TM4C123-family MCU in the same 100-LQFP package — the base product number TM4C123 covers multiple Flash and RAM density options that share the same pinout and core. Check the specific Flash and RAM sizes against your firmware image before swapping.

What is TM4C123BH6PZI7R's listed speed?

80 MHz, with a single-precision FPU on the Cortex-M4F core.
