80 MHz Cortex-M4F with FPU — compute headroom for control loops
The TM4C123GH6ZRBT7R is a Texas Instruments Tiva™ C series 32-bit ARM Cortex-M4F microcontroller running at 80 MHz. The floating-point unit (FPU) on the M4F core handles PID loops, sensor fusion, and real-time math without a software emulation penalty — useful in motor-drive and industrial-control applications where the control-law update rate ties directly to the core speed. 256 KB of Flash program memory and 32 KB of RAM give enough room for a real-time OS, a USB stack, and a moderate application image without squeezing code into overlay segments.
120 I/O and peripheral set — what connects where
120 general-purpose I/O pins, all accessible from the 157-ball BGA Microstar Junior (9x9 mm) package.
Industrial temperature range — deployment context
Supply range is 1.08 V to 3.63 V.
