The Advanced Micro Devices AM79C940BKC is a CMOS LAN controller featuring four asynchronous and synchronous serial communication channels. This component supports Ethernet communication standards and utilizes NRZ and Biphase-Level (Manchester) encoding/decoding methods. With a maximum clock frequency of 25 MHz and a 16-bit external data bus, it offers efficient data handling. The AM79C940 series controller operates within a 4.75V to 5.25V supply voltage range, with a nominal value of 5.0V, and includes low-power modes. Its 100-terminal PQFP package (JESD-30 code R-PQFP-F100) is suitable for surface-mount applications. Boundary scan capabilities are integrated. This component finds application in networking equipment and telecommunications infrastructure.
