1. System Overview
The CP2112 is a highly-integrated HID USB-to-SMBus Bridge providing a simple solution for controlling SMBus
slave devices with USB and using a minimum of components and PCB space. The CP2112 includes a USB 2.0
full-speed function controller, USB transceiver, oscillator, and a one-time programmable ROM in a compact
4 x 4 mm QFN-24 package (sometimes called “MLF” or “MLP”).
The on-chip, one-time programmable ROM provides the option to customize the USB Vendor ID, Product ID,
Manufacturer Product String, Product Description String, Power Descriptor, Device Release Number, and Device
Serial Number as desired for OEM applications.
The CP2112 uses the standard USB HID device class, which is natively supported by most operating systems. A
custom driver does not need to be installed for this device. Windows applications communicate with the CP2112
through a Windows DLL, which is provided by Silicon Labs. The interface specification for the CP2112 is also
available to enable development of an API for any operating system that supports HID.
The CP2112 SMBus interface includes the SDA and SCL signals needed for SMBus communication and is
configurable. The configurable options include the clock speed, read/write timeouts, retry counter timeout, SCL low
timeouts, and a 7-bit device address. The CP2112 will only ACK the 7-bit device address assigned to it but will not
respond to any read/write requests. External pull-up resistors are needed for the SCL and SDA signals.
The device also features a total of eight GPIO signals. The GPIO signals are controlled through USB and can be
configured as Input/Output and Open-Drain/Push-Pull. Three of the GPIO signals support alternate features
including a configurable clock output (48 MHz to 94 kHz) and TX and RX LED toggle. Support for I/O interface
voltages down to 1.8 V is provided via a VIO pin.
An evaluation kit for the CP2112 (Part Number: CP2112EK) is available. It includes a CP2112-based HID USB-to-
SMBus evaluation board, Windows DLL and test application, USB cable, and full documentation. Go to
www.silabs.com for the latest application notes and product support information for the CP2112. Contact a Silicon
Labs sales representatives or go to www.silabs.com to order the CP2112 Evaluation Kit.
