It carries 1 MB of Flash and 256 KB of SRAM, plus 6 KB of EEPROM.
The 120 MHz core speed, combined with the single-cycle MAC and FPU, handles real-time control loops alongside a TCP/IP stack.
Texas Instruments lists the lifecycle stage as EOL hot. The base product number TM4C1290 remains active across many variants.
The TM4C1294NCZADI3R shares the same 212-NFBGA package and peripheral set (Ethernet, CAN, USB, 140 I/O) and is pin-compatible. Verify that the 1 MB Flash and 256 KB RAM match your firmware image and that the temperature grade (-40 to 85°C) is acceptable before substituting.
The core runs at 120 MHz, based on the ARM Cortex-M4F with single-cycle multiply and floating-point unit.
