Product details

The TM4C123GH6PMT7R is a Texas Instruments Tiva C Series 32-bit MCU built around an ARM Cortex-M4F core with single-precision FPU, clocked at 80 MHz.

Industrial temperature grade and connectivity

Rated -40°C to 105°C, this part is specced for motor drive cabinets, outdoor telecom shelters, and engine-bay-adjacent control modules. The peripheral set includes CAN, USB OTG, I²C, SPI, SSI, UART, and QEI — so it can talk to a VFD over CANopen, log data to a USB stick, and read an incremental encoder on the same die. 43 GPIOs in the 64-LQFP leave enough headroom for a keypad, a small TFT, and a few status LEDs without needing a port expander.

This part carries an EOL-hot lifecycle marker. The manufacturer has issued a last-time-buy notice — production is winding down.

Frequently asked questions

What is the core speed of TM4C123GH6PMT7R?

The ARM Cortex-M4F core runs at 80 MHz, delivering roughly 100 MIPS with single-cycle multiply and hardware FPU for real-time math.
