The new family of six devices enables engineers to bring real-time Industrial Internet of Things (IIoT) capabilities to rugged factory automation systems, motor drives, and test and measurement equipment. The new family meets stringent electromagnetic interference (EMI) and electromagnetic compatibility (EMC) standards, reduces power consumption, and offers designers flexibility with multiple temperature, media access control (MAC) interface and packaging options. Features include latency of less than 400 ns at 1000 Mbps and 100 Mbps; ESD protection that exceeds 8 kV to surpass IEC 61000-4-2 standards; wake-on-local area network (LAN) (WoL); and power-down modes that offer energy savings when the system is in a standby state, while active power consumption is less than 460 mW; and a range of options over the family that allow designers to design across the full temperature range from -40 to 105 ºC. Available evaluation modules enable designers to quickly and easily evaluate the new devices, and can jumpstart their designs with the EMI/EMC-compliant industrial-temperature-grade Gigabit Ethernet reference design, which includes the Sitara AM335x processor with integrated Ethernet MAC and switch.
