Advanced Micro Devices AM79C940 is a quad-channel LAN controller designed for high-performance networking applications. This CMOS component, part of the AM79C940 series, operates at a maximum clock frequency of 25 MHz and supports data transfer rates up to 1.25 Mbps. It features four serial I/O channels with support for ASYNC and BIT, as well as SYNC, BYTE communication standards, employing NRZ and BIPH-LEVEL (MANCHESTER) encoding/decoding methods. The controller boasts a 16-bit external data bus and a 5-bit address bus width, with PCMCIA bus compatibility. It includes low-power modes and boundary scan capabilities for enhanced debug and testing. The AM79C940 is housed in a 100-terminal PQFP package (R-PQFP-G100) with a 0.65 mm terminal pitch, suitable for surface mounting in demanding environments operating between -40°C and 85°C. Typical applications include telecommunications, industrial automation, and networking infrastructure.
