CP2201-GMR

Controllers Overview

The CP2201-GMR is a single-chip Ethernet controller from Silicon Laboratories, featuring an integrated IEEE 802.3 MAC and 10BASE-T PHY. It operates within a supply voltage range of 3.1 to 3.6 V and supports a specified operating temperature range of –40 to +85 °C. The component is housed in a Pb-free 28-pin QFN package with a 5x5 mm footprint. It includes 8 kB of factory pre-programmed ISP non-volatile Flash memory containing a unique 48-bit MAC address. The device utilizes an 8-bit parallel host interface supporting Intel or Motorola bus formats in multiplexed or non-multiplexed modes.

Controllers Feature Summary

• Integrates IEEE 802.3 MAC and 10BASE-T PHY for full Ethernet connectivity
• Includes 8 kB internal Flash memory with pre-programmed unique MAC address
• Supports multiplexed and non-multiplexed parallel host interfaces
• Features automatic polarity detection, collision retransmission, and CRC generation

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 against the manufacturer's current documentation to confirm package type and lead time requirements. Ensure that the procurement specifications align with the 28-pin QFN form factor and the required industrial temperature range. Confirm RoHS compliance status through official datasheets prior to finalizing orders.

Controllers Selection Notes

Select the CP2201-GMR when a compact 28-pin QFN package is required compared to the 48-pin TQFP variant. This model provides identical functional capabilities including the integrated MAC/PHY and Flash memory. Ensure the host system supports the necessary parallel interface protocols and has sufficient I/O pins for the chosen bus mode configuration.

Controllers Part Context

The CP2201-GMR belongs to the CP2200/1 family of single-chip Ethernet controllers manufactured by Silicon Laboratories. It serves as the 28-pin QFN version of the CP2200 series, offering the same core Ethernet functionality in a smaller footprint. The part number indicates the specific package style and lead-free composition defined by the manufacturer.

Controllers Replacement Considerations

The CP2200-GQ is the primary alternative within the same product family, differing only in its 48-pin TQFP package. No other direct cross-model replacements are documented in the provided source material.
