The Advanced Micro Devices AM79C940-16JC is a CMOS serial I/O and communication controller featuring three Ethernet channels. This component supports multiple Ethernet standards including 10BASE2, 10BASE5, 10BASE-T, and 10BASE-F, adhering to IEEE 802.3 specifications. It utilizes Biphase Level (Manchester) encoding/decoding for data transmission and features a 16-bit external data bus. The device operates with a nominal supply voltage of 5.0000V, ranging from 4.7500V to 5.2500V, and has a maximum clock frequency of 16 MHz. Designed for surface mounting, it is housed in an 84-terminal PQCC package. Boundary scan capabilities are integrated, and the controller offers low-power mode functionality. Applications for this component include networking infrastructure and communication systems.
