FAQs

What is CP2120?

The CP2120 is a highly integrated USB-to-I2C bridge controller designed by Silicon Labs. It provides a convenient solution for connecting I2C devices to a host computer through a USB interface, enabling easy communication and control of I2C peripherals.

How Does CP2120 Work?

The CP2120 works by converting USB data from the host computer into I2C bus commands, allowing seamless communication with I2C devices. It integrates USB transceiver, voltage regulator, and I2C communication logic into a single chip, simplifying the design and implementation of USB-to-I2C bridge applications.

How Many Pins does CP2120 have and What are the Functions of the Pinout Configuration?

The CP2120 is typically available in a 20-pin QFN (Quad Flat No-leads) package. The pinout configuration includes:

  • VDD: Power supply pin.
  • GND: Ground pin.
  • USB D+/D-: USB data lines for connection to the host computer.
  • SCL, SDA: I2C clock and data lines for communication with I2C devices.
  • INT: Interrupt output pin for asynchronous event notification.
  • GPIO: General-purpose input/output pin for additional control or monitoring.
  • ADDR0, ADDR1: Address select pins for I2C address configuration.

What are the Pros and Cons of CP2120?

Pros:

  • Integration: Combines USB transceiver and I2C communication logic into a single chip, reducing external component count.
  • Plug-and-Play: Provides a seamless bridge between USB and I2C without the need for complex driver development.
  • Flexible Configuration: Supports configurable I2C slave addresses for interfacing with multiple devices.
  • Low Power Consumption: Operates with low power, suitable for energy-efficient designs.

Cons:

  • Package Handling: The QFN package may require careful handling and soldering techniques.
  • Complexity for Beginners: May require understanding of USB and I2C protocols for effective usage.
  • Limited I/O: Provides a limited number of GPIO pins for additional control or monitoring.

Are There Any Equivalents/Alternatives to CP2120 for Recommendation?

  • The FTDI FT260 from Future Technology Devices International provides similar USB-to-I2C bridge functionality.
  • Alternatives to the CP2120 include the CY7C65215 from Cypress Semiconductor and the FT232H from FTDI, which offer USB-to-I2C capabilities with additional features.
