CS8900A-CQ3

Part points

• The CS8900A-CQ3 chip is a single-chip Ethernet controller designed for use in embedded systems. It provides full-duplex 10Mbps and 100Mbps operation, as well as an MII (Media Independent Interface) and an internal 256-byte transmit/receive buffer. The chip also features a built-in AUI (Attachment Unit Interface) and supports both 3.3V and 5V power supplies.

• Equivalent

  Some equivalent products of the CS8900A-CQ3 chip include the CS8900A-CQZ, CS8900A-CQ, and CS8900A-CQZ chips. These chips are all part of the CS8900A family of Ethernet controllers and offer similar features and functionality to the CS8900A-CQ3 chip.

• Features

  The CS8900A-CQ3 is a 10BASE-T/100BASE-TX Ethernet controller with integrated MAC and PHY. It has a 16-bit parallel interface, 8KB transmit/receive packet buffers, and supports both half and full duplex operation. It also features a built-in programmable wait state generator and on-chip 8KB RAM for packet data storage.

• Pinout

  The CS8900A-CQ3 is a single-chip PCI Ethernet controller with an integrated 10/100 PHY. It has a 100-pin LQFP (Low-profile Quad Flat Package). The pin count and functions vary based on the package type, but generally include power, data, clock, and control signals for Ethernet communication.

• Manufacturer

  The CS8900A-CQ3 is manufactured by Cirrus Logic, Inc., which is a fabless semiconductor company. This means that although they design and market their products, they do not have their own manufacturing facilities, but instead outsource the actual production of their chips to third-party foundries.

• Application Field

  The CS8900A-CQ3 is commonly used in embedded systems, industrial automation, and networking equipment. It is often utilized for connecting devices to local area networks (LANs) or the internet, and for enabling communication between different devices within a network.

• Package

  The CS8900A-CQ3 chip is available in a 100-pin LQFP (Low-profile Quad Flat Package) form. The package size is 14mm x 14mm and features a quad flat design with a thin profile.
