The Advanced Micro Devices AM79C940AVC is a 4-channel LAN controller built on CMOS technology. This component, part of the AM79C940 series, operates with a maximum clock frequency of 25 MHz and supports communication standards including ASYNC, BIT, SYNC, BYTE, and Ethernet. Data encoding and decoding methods utilized are NRZ and BIPH-LEVEL (Manchester). It features a 16-bit external data bus and accepts a supply voltage range of 4.75V to 5.25V, with a nominal value of 5.0V. The device includes low power modes and boundary scan capabilities. Housed in an 80-terminal PQFP package (JESD-30 Code: S-PQFP-G80) with a 0.50mm terminal pitch, this surface-mount component is suitable for applications in networking and communication infrastructure. The operating temperature range is 0°C to 70°C.
