The TM4C129XNCZADI3R is a Texas Instruments Tiva™ C Series microcontroller built around an ARM® Cortex®-M4F core with single-precision floating-point unit, clocked at 120 MHz. That clock rate, combined with the 1 MB on-chip Flash and 256 KB SRAM, puts it in the performance tier for industrial control loops, Ethernet packet processing, and real-time sensor fusion where you need both DSP extensions and hardware divide without cycle-counting. The 120 MHz core speed means the part can sustain a TCP/IP stack, a USB host stack, and a control loop on the same silicon without external RAM for moderate workloads. The 256 KB SRAM is enough for two full Ethernet jumbo frames plus a 320x240 frame buffer, so display and connectivity can coexist.
Peripheral set — Ethernet, CAN, USB OTG, and 140 GPIO
Brown-out detect and POR are integrated, reducing external supervisor IC count.
212-NFBGA package — what the 10x10 mm footprint means for the board
It remains suitable for new production designs and multi-year BOM commitments.
