Product details

120 MHz Cortex-M4F with integrated Ethernet — what that means for a motor-drive or gateway BOM

It carries 1 MB of program Flash and 256 KB of SRAM, plus 6 KB of EEPROM for nonvolatile parameter storage.

Memory and peripheral sizing — the BOM-fit check

With 1 MB of Flash you can host a full Ethernet stack, a CANopen or EtherCAT slave library, and the application code without needing external serial Flash for most designs. The 256 KB SRAM is enough for double-buffered Ethernet frames and a moderate data-logging buffer. The 6 KB EEPROM is useful for storing calibration constants and node IDs without wearing the Flash. The 90 GPIOs in the 128-TQFP package give headroom for a parallel LCD interface or a bank of opto-coupled inputs on a motor-drive control card.

Frequently asked questions

What is the difference between TM4C129DNCPDTT3 and TM4C129ENCPDTT3?

The TM4C129ENCPDTT3 is a pin-compatible variant within the same Tiva C family. The primary difference is that the 'E' version adds a cryptographic accelerator (AES, DES, SHA) and a hardware CRC module, while the 'D' version (this part) omits those security blocks. Both share the same 120 MHz Cortex-M4F core, 1 MB Flash, 256 KB SRAM, Ethernet MAC+PHY, and CAN controllers. If your application does not need hardware cryptography, the TM4C129DNCPDTT3 is the cost-optimized choice.
