Product details

That FPU is the differentiator here: it handles PID coefficients, sensor fusion math, and filter taps in hardware instead of soft-emulated fixed-point, which saves both CPU cycles and code space.

Peripheral set — what connects without extra glue

The connectivity list is what saves board space: CANbus, USB OTG, and multiple serial interfaces (UART, SPI, I²C, SSI, Microwire) mean most industrial or automotive subnets connect directly. The 12-channel 12-bit ADC covers analog inputs like potentiometers, current shunts, or thermistor bridges without an external converter.

That means normal supply through distribution; no urgency to stockpile or qualify a replacement.

Frequently asked questions

What is TM4C123FH6PMI7's core speed?

The TM4C123FH6PMI7 runs at 80 MHz on its ARM Cortex-M4F core.

What is the closest pin-compatible alternative to TM4C123FH6PMI7?

Within the Tiva C TM4C123 series, density variants like TM4C123GH6PM (with more Flash/RAM) share the same 64-LQFP footprint and peripheral map, making them drop-in replacements for BOM upgrades.
