It carries 1 MB of Flash, 256 KB of SRAM, and 6 KB of EEPROM on-chip.
The 256 KB SRAM handles packet buffers and data arrays without external memory.
No official pin-compatible second source or direct successor is listed for this exact 128-pin Tiva C variant with Ethernet and CAN. The TM4C1294NCPDTI3 is the highest-density member of its package family; a design spin to a different MCU may be required for long-term supply.
The ARM Cortex-M4F core runs at 120 MHz, with a single-cycle multiply and hardware divide, plus a single-precision FPU for real-time control loops.
