The Advanced Micro Devices AM79C940AKC-W is a CMOS LAN controller featuring four serial I/O channels. Operating within a 4.75V to 5.25V supply range, this component supports asynchronous, bit-oriented, synchronous byte, and Ethernet communication standards. Data encoding and decoding methods include NRZ and Biphase-Level (Manchester). The device integrates a 16-bit external data bus and a 5-bit address bus, with a maximum clock frequency of 25 MHz. Boundary scan capabilities are present, and it offers a low-power mode. Packaged in a 100-terminal PQFP (R-PQFP-G100) with a 0.65mm terminal pitch, this component is suitable for surface mounting. Its operating temperature range is 0°C to 70°C. This controller finds application in networking equipment and communication systems.
