CP2108-B02-GMR

Controllers Overview

The CP2108-B02-GMR is a highly integrated USB to Quad UART Bridge Controller manufactured by Silicon Labs. It provides four asynchronous serial data buses with full modem control signals within a compact 9 mm x 9 mm 64-pin QFN package. The device supports USB 2.0 full-speed operation at 12 Mbps and includes an on-chip oscillator, EEPROM for customization, and a voltage regulator. Recommended operating conditions specify a supply voltage (VDD) of 3.0 V to 3.6 V and an operating temperature range from -40 °C to +85 °C. Supply current is typically 56 mA in normal mode.

Controllers Feature Summary

• Integrates four independent UART interfaces with full modem control signals
• Includes an on-chip programmable EEPROM for customizing product information
• Features a built-in voltage regulator and eliminates the need for external crystals or resistors

Controllers Applications

• Instrumentation systems
• Industrial control equipment
• Servers
• Point-of-Sale products

Controllers Procurement Notes

Verify component authenticity through authorized channels as this part number may be discontinued. Confirm that the specific B02 firmware revision matches your system requirements before procurement. Ensure proper handling procedures are followed due to moisture sensitivity classification. Review the latest datasheet revisions to confirm pinout and electrical characteristics remain consistent with your design specifications.

Controllers Selection Notes

Select this component when multiple UART connections are required via a single USB interface. It is suitable for designs needing hardware flow control and configurable GPIOs. Consider the 64-pin QFN package constraints during PCB layout. Verify that the host PC environment supports the provided Virtual COM Port drivers for Windows, Mac, and Linux platforms.

Controllers Part Context

This component belongs to the CP2108 family of USB-to-UART bridge controllers. It shares the same core architecture and package type as other variants like the CP2108-B03-GMR. Differences between variants typically involve firmware revisions or specific configuration options stored in the internal EEPROM rather than changes to the physical hardware or pinout.

Controllers Replacement Considerations

Public confirmed substitute part numbers include CP2108-B03-GMR.
