CP2112-F02-GMR

The Silicon Labs CP2112-F02-GMR is a highly integrated single-chip solution designed to bridge USB to the SMBus (System Management Bus) master interface. This device simplifies the design of USB-to-SMBus communication, eliminating the need for external resistors or crystals due to its integrated USB transceiver.

Key features include compliance with USB Specification 2.0 at full-speed (12 Mbps) and support for USB suspend states. The CP2112 acts as an SMBus master device and includes an integrated 512-byte SMBus data buffer. It offers 8 configurable GPIO pins that can function as inputs, open-drain, or push-pull outputs, and can also provide a configurable clock output for external devices ranging from 48 MHz down to 94 kHz.

The device operates within a temperature range of -40°C to +85°C and is available in a compact 24-pin QFN (4x4 mm) package. Supply voltage options include self-powered mode (3.0 V to 3.6 V) and USB bus-powered mode (4.0 V to 5.25 V), with I/O voltage configurable from 1.8 V to VDD.

This bridge IC is suitable for various applications requiring USB connectivity to SMBus-controlled devices, such as system monitoring, power management, and sensor interfacing. Its standard USB class device nature means it requires no custom drivers for Windows, Mac OS X, and Linux operating systems.
