Product details

Tiva C series MCU with integrated Ethernet and industrial connectivity

It carries 1 MB of Flash program memory, 256 KB of SRAM, and 6 KB of EEPROM, with 140 general-purpose I/O lines routed to a 212-ball NFBGA package measuring 10x10 mm.

120 MHz Cortex-M4F — processing headroom for protocol stacks and real-time loops

The 120 MHz core with FPU handles Ethernet TCP/IP offload, CAN message handling, and control-loop calculations without a separate communications processor. This matters when the BOM has to consolidate an MCU plus a network coprocessor into a single device.

Memory sizing for firmware and data buffering

1 MB Flash accommodates a full Ethernet stack plus application code; 256 KB SRAM supports packet buffers and multi-tasking. The 6 KB EEPROM stores calibration constants and network parameters without requiring external serial memory.

Frequently asked questions

What is the difference between TM4C129XNCZADT3 and TM4C129XNCZADI3?

The only difference is the operating temperature range: the 'T3' variant is rated -40°C to 105°C, while the 'I3' variant is rated -40°C to 85°C. All other specifications — 120 MHz Cortex-M4F, 1 MB Flash, 256 KB RAM, connectivity, package — are identical.
