1.3.8 Serial Communications Peripherals
The TM4C129XNCZAD controller supports both asynchronous and synchronous serial
communications with:
■ 10/100 Ethernet MAC with Advanced IEEE 1588 PTP hardware and both Media Independent
Interface (MII) and Reduced MII (RMII) support; integrated PHY provided
■ Two CAN 2.0 A/B controllers
■ USB 2.0 Controller OTG/Host/Device with optional high speed using external PHY through ULPI
interface
■ Eight UARTs with IrDA, 9-bit and ISO 7816 support.
■ 1-Wire Master module with the capability of providing power and data over a single bi-directional
wire
■ Ten I
2
C modules with four transmission speeds including high-speed mode
■ Four Quad Synchronous Serial Interface modules (QSSI) with bi- and quad-SSI support
The following sections provide more detail on each of these communications functions.
