What this Tiva C part brings to the board
It carries 512 KB of Flash and 256 KB of SRAM, plus 6 KB of EEPROM for parameter storage that survives a firmware reload.
120 MHz Cortex-M4F — what the clock buys you
The FPU accelerates sensor fusion or motor-control math.
Memory sizing for the firmware load
512 KB of Flash is enough for a full TI-RTOS or FreeRTOS application with a web server, CANopen stack, and a modest data-logging buffer. The 256 KB SRAM leaves headroom for Ethernet packet buffers and a large display frame buffer via the EBI.
