Product details

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.

Frequently asked questions

What is the TM4C1294KCPDTI3 used for?

It is a 32-bit ARM Cortex-M4F MCU designed for connected industrial control: Ethernet gateways, CAN bus nodes, building automation controllers, and motor drives that need a real-time control loop plus networking. The 120 MHz core, 512 KB Flash, and 256 KB SRAM handle a full TCP/IP stack and sensor fusion algorithms.

What is the closest pin-compatible alternative to the TM4C1294KCPDTI3?

The TM4C1294NCPDTI3 is a pin-compatible sibling within the same Tiva C family, sharing the same 512 KB Flash, 256 KB SRAM, and 128-TQFP footprint. The main difference is in the Ethernet PHY configuration, so verify your PHY driver and transformer interface before swapping.
