120 MHz Cortex-M4F with integrated Ethernet and USB OTG
The 6 KB EEPROM handles calibration constants and configuration parameters that survive firmware updates. The connectivity set includes a 10/100 Ethernet MAC+PHY, USB 2.0 OTG (host and device), two CAN 2.0B controllers, and multiple serial interfaces (UART, I²C, SPI, SSI, IrDA, QEI). This makes the part a natural fit for industrial gateways, programmable logic controllers, building automation controllers, and medical equipment that bridge sensor networks to an Ethernet backbone. The 212-NFBGA (10x10 mm) package delivers 140 GPIOs in a compact footprint, but the 0.5 mm ball pitch demands careful PCB routing and a controlled reflow profile.

The 1 MB program Flash is organized for efficient firmware OTA updates — the 256 KB SRAM can buffer a new image while the current one runs. The 6 KB EEPROM is separate from the Flash array, so configuration data survives reprogramming without needing a dedicated sector. The 24-channel 12-bit ADC covers multi-sensor analog front ends without external muxing. The brown-out detect and POR eliminate external supervisor ICs in cost-sensitive designs.
For new designs, the Tiva C family has broad second-source compatibility across the TM4C129x series, but verify pin compatibility at the specific package variant.
