Product details

The Texas Instruments TM4C1299KCZADT3 is a Tiva™ C Series ARM Cortex-M4F with floating-point unit, clocked at 120 MHz. It carries 512 KB of Flash and 256 KB of RAM — enough headroom for a TCP/IP stack, a real-time control loop, and a modest data buffer without reaching for external memory. The 6 KB EEPROM stores calibration constants and MAC addresses without wearing the main Flash. Connectivity includes Ethernet MAC+PHY, CANbus, USB OTG, and EBI/EMI. The 140 GPIO pins, 24-channel 12-bit ADC, and motion-control PWM peripherals are on-chip.

At 120 MHz, the Cortex-M4F FPU handles single-cycle float multiply. The 256 KB of RAM is available for application use.

The DMA engine offloads peripheral-to-memory transfers (Ethernet frames, ADC results) without CPU intervention, which matters for deterministic response times.

Frequently asked questions

What is TM4C1299KCZADT3's listed speed?

The core runs at 120 MHz. That is the ARM Cortex-M4F maximum clock frequency for this device, with a single-cycle multiply and hardware FPU.

What is the closest pin-compatible alternative to TM4C1299KCZADT3?

The TM4C1294NCPDT and TM4C1297NCZAD are pin-compatible siblings in the same 212-ball BGA package. They share the same peripheral set but offer less Flash (512 KB vs 1 MB on the 1299) and fewer GPIO pins. For a drop-in replacement with the same memory and I/O count, the TM4C1299 is the highest-density option in the family.

What compliance documentation does Texas Instruments provide for TM4C1299KCZADT3?

Texas Instruments provides RoHS and REACH compliance declarations for this part. The package is a green-molding compound (halogen-free) as standard for TI's Tiva C series. UL and IEC certification documents are available on request through the distributor.
