The Advanced Micro Devices AM79C940JC is a high-performance CMOS LAN controller from the AM79C940 series. This component features four serial I/O channels, each capable of supporting communication standards including ASYNC, BIT, SYNC, BYTE, and Ethernet. Data transfer rates can reach up to 1.25 Mbps, with data encoding and decoding methods supporting NRZ and BIPH-LEVEL (Manchester). The device operates on a 5V supply voltage (4.75V to 5.25V) and consumes a maximum of 75mA. Designed for surface mounting, it is housed in an 84-terminal PQCC (J-Bend terminals, 1.27mm pitch) package. Additional features include bus compatibility with PCMCIA, boundary scan functionality, and low-power modes. This component is suitable for applications in networking and communication systems.
