120 MHz Cortex-M4F with integrated Ethernet and CAN
The Texas Instruments TM4C1299NCZADT3R is a 32-bit ARM Cortex-M4F microcontroller from the Tiva C series, clocked at 120 MHz with a single-core architecture. It carries 1 MB of Flash program memory, 256 KB of SRAM, and 6 KB of EEPROM on-chip, alongside 140 general-purpose I/O lines. The part integrates a full set of connectivity peripherals including CANbus, Ethernet MAC+PHY, USB OTG, I²C, SPI, SSI, UART/USART, and QEI for motor feedback. An internal oscillator keeps the BOM count low, and the 24-channel 12-bit ADC handles analog inputs without an external converter. This MCU is built for industrial control, building automation gateways, and IoT edge nodes that need both real-time control and network connectivity in a single package.
Memory and peripheral fit for gateway designs
The 1 MB Flash and 256 KB SRAM support a full TCP/IP stack with room for application code and data buffers. The 6 KB EEPROM stores calibration constants or network parameters without wearing the Flash. On-chip Ethernet and dual CANbus let this part serve as a protocol converter between fieldbus and IP networks, eliminating a separate communication coprocessor.
Lifecycle and sourcing
The TM4C1299NCZADT3R is listed as Active in production. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
