CP2200-GQR

Controllers Overview

The CP2200-GQR is a single-chip Ethernet controller integrating an IEEE 802.3 MAC and 10BASE-T PHY. It features an 8-bit parallel host interface supporting Intel and Motorola bus formats in multiplexed or non-multiplexed modes, achieving transfer rates exceeding 30 Mbps. The device includes 8 kB of ISP flash memory pre-programmed with a unique 48-bit MAC address. Operating on a 3.1 to 3.6 V supply, it supports full/half duplex auto-negotiation and provides dedicated LED drivers. The component is housed in a 28-pin QFN package measuring 5x5 mm.

Controllers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature range. Confirm that the ordering part number matches the required pin count and footprint. Check for any revision-specific behavior notes in the datasheet before finalizing procurement specifications.

Controllers Selection Notes

Select this component when a compact solution for 10BASE-T connectivity is required without external PHYs. Ensure the host processor supports the necessary parallel interface timing and has sufficient I/O pins for the chosen bus mode. Verify voltage compatibility between the host logic levels and the controller's 5 V tolerant inputs.

Controllers Part Context

This model belongs to the CP2200/1 family of single-chip Ethernet controllers from Silicon Labs. It serves as a cost-effective alternative to separate MAC and PHY solutions, reducing board space and component count. The family is designed for embedded applications requiring reliable Ethernet communication with minimal host processor overhead.

Controllers Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains identical pinout, voltage requirements, and interface protocol support.
