CP2200-GQ

Controllers Overview

The CP2200-GQ is a single-chip Ethernet controller from Silicon Labs, featuring an integrated IEEE 802.3 MAC and 10BASE-T PHY. It supports full/half duplex with auto-negotiation and operates within a supply voltage range of 3.1 to 3.6 V. The device includes 8 kB of ISP non-volatile Flash memory pre-programmed with a unique 48-bit MAC address. It utilizes an 8-bit parallel host interface supporting Intel or Motorola bus formats in multiplexed or non-multiplexed modes, achieving transfer rates exceeding 30 Mbps. The component is housed in a Pb-free 48-pin TQFP package with dimensions of 9x9 mm and functions across a temperature range of –40 to +85 °C.

Controllers Feature Summary

• Integrates IEEE 802.3 MAC and 10BASE-T PHY for direct network connectivity
• Includes 8 kB factory pre-programmed Flash memory eliminating external EEPROM requirements
• Supports 5 V tolerant I/O and multiple power modes for system efficiency
• Provides dedicated LED output drivers for link and activity status indication

Controllers Applications

• Remote sensing and monitoring systems
• Inventory management devices
• VoIP phone adapters
• Point-of-sale terminals
• Embedded Web Servers

Controllers Procurement Notes

Verify the specific ordering suffix matches the required package type. The CP2200-GQ designation corresponds to the 48-pin TQFP variant. Confirm that the host processor interface timing aligns with the specified parallel bus formats. Ensure supply voltage constraints between 3.1 V and 3.6 V are strictly maintained during operation to prevent damage.

Controllers Selection Notes

Select this component when a compact solution integrating both MAC and PHY layers is required without external memory. The 48-pin TQFP package offers ample pin access for non-multiplexed interfaces if fewer pins are available on the host. Consider the 28-pin QFN alternative if space is severely constrained and multiplexed addressing is acceptable.

Controllers Part Context

This part belongs to the CP2200/1 series of single-chip Ethernet controllers. The CP2200-GQ specifically denotes the 48-pin TQFP version, while the CP2201-GM represents the 28-pin QFN variant. Both share identical internal functionality but differ in physical footprint and pin count.

Controllers Replacement Considerations

Public confirmed substitute part numbers: CP2201-GM (28-pin QFN equivalent).
