Microchip Technology COM20019 series LAN controller, part number COM20019I-LJP, offers a single-channel communication interface operating at a maximum data transfer rate of 0.0390625 Mbps. This CMOS component features an 8-bit external data bus and a 1024-word (8-bit wide) on-chip data RAM. It supports both synchronous and byte communication standards and is compatible with ISA and RS485 bus architectures. The device operates within a temperature range of -40°C to +85°C and requires a supply voltage between 4.5V and 5.5V, with a nominal 5.0V. Packaged in a 28-terminal PQCC (J-bend terminals, 1.27mm pitch), this surface-mount device includes low-power mode functionality. Applications for this component can be found in industrial automation 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.
