The TM4C1294NCZADI3R is a Texas Instruments Tiva C series 32-bit ARM Cortex-M4F microcontroller clocked at 120 MHz, with a single-precision floating-point unit on die. That FPU handles PID coefficients and sensor fusion math without a software emulation tax — the cycle budget stays predictable for motor-drive current loops or Ethernet packet processing. 1 MB of Flash program memory and 256K x 8 of RAM give the firmware stack room for a TCP/IP stack, a USB host stack, and a real-time OS without squeezing the application code.
Lifecycle status — EOL hot, last-time-buy window
The TM4C1294NCZADI3R carries an EOL hot lifecycle stage, meaning Texas Instruments has announced end-of-life and a last-time-buy window is active or closing. For a BOM that depends on this exact package and pinout, the procurement action is to secure lifetime-buy quantities or identify a migration path before the LTB closes. No official TI successor is listed for this specific NFBGA variant; the TM4C1294 family shares the same core and peripheral set across package options, but a pin-compatible drop-in in a different package does not exist.
