It carries 1 MB of Flash program memory, 256K x 8 of SRAM, and 6K x 8 of EEPROM, making it a dense, connected controller for industrial gateways, building automation controllers, and HMI panels that need Ethernet, dual CAN, and USB OTG on a single chip.
The 120 MHz core with hardware FPU handles real-time control loops and protocol stacks without an external co-processor. For a motor-drive application using the integrated motion-control PWM and QEI, the cycle budget leaves headroom for a Modbus TCP stack on the Ethernet port. The 90 general-purpose I/O, spread across a 128-TQFP package, give enough pins to capture encoder feedback and drive a local display without a port expander.
The TM4C1290NCPDTT3 is flagged as end-of-life hot (EOL hot). No official successor order code is listed in the available records.
