The Advanced Micro Devices AM7990JC is a single-channel LAN controller from the AM7990 series, fabricated using NMOS technology. This component supports asynchronous, bit-synchronous, byte-synchronous, and Ethernet communication standards, with a maximum data transfer rate of 1.25 Mbps. It features a 16-bit external data bus and is compatible with 8086, 68000, Z8000, and LSI-11 bus architectures. The device operates within a temperature range of 0°C to 70°C and requires a supply voltage of 5.0V nominal. Packaged in a 68-terminal PQCC (J-Bend) with a 1.27mm terminal pitch, this surface-mount device is suitable for applications in networking and communication systems. The AM7990JC includes one DMA channel for efficient data handling.
