Quality Control: Learn More

The Microchip Technology COM20022I is a CMOS LAN controller supporting ASYNC and SYNC communication standards. This component features one serial I/O channel with a maximum data transfer rate of 1.25 Mbps. It offers compatibility with 8051 and 6801 bus architectures, utilizing an 8-bit on-chip data RAM and 2048 RAM words for buffering. The device operates within a supply voltage range of 4.5V to 5.5V, with a nominal voltage of 5.0V, and boasts a maximum clock frequency of 20 MHz. Designed for surface mounting, the COM20022I is housed in a 48-terminal PQFP package (JESD-30 code S-PQFP-G48) with a terminal pitch of 0.50mm. Its operating temperature spans from -40°C to +85°C. This controller is suitable for applications requiring serial communication, including networking and industrial automation. The data encoding/decoding method employed is NRZ.

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.
