1 MB Flash and 256 KB SRAM — firmware headroom and buffer space
The 1 MB Flash program memory handles large firmware stacks like a full TCP/IP stack with TLS, a CANopen node, and a USB host stack simultaneously. The 256 KB SRAM provides enough buffer space for Ethernet packet queues and double-buffered display frames without starving the control loops. The 6 KB EEPROM is useful for calibration constants and MAC addresses that must survive a firmware update.
The TM4C129ENCPDTI3 is in an end-of-life (EOL) stage. The manufacturer has issued a last-time-buy notice, and new-production allocations are closed.
