120 MHz Cortex-M4F with integrated Ethernet and CAN
It carries 512 KB of Flash, 256K x 8 SRAM, and 6K x 8 EEPROM. Connectivity includes Ethernet, CAN, USB OTG, UART, SPI, and I²C.
The TM4C129XKCZADI3R carries an EOL hot lifecycle status. New production from TI is not available; supply runs through surplus and broker channels. The base product number is TM4C129.
Peripherals and data conversion
On-chip peripherals include a 24-channel 12-bit ADC, motion-control PWM, quadrature encoder interface (QEI), DMA, brown-out detect, and watchdog timer. The oscillator is internal, which saves an external crystal for non-precision timing. The ADC channel count suits multi-phase motor current sensing or multi-axis encoder feedback without external muxing.
