Manufacturer: Advanced Micro Devices

Categories: Serial IO/Communication Controllers

Quality Control: Learn More

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.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
