SILICON LABS CP2102N USB to UART Bridge, 3V to 3.6V, QFN24

The SILICON LABS CP2102N-A02-GQFN24 is a highly integrated USB to UART bridge IC, part of the USBXpress family, designed to simplify serial communication development. It incorporates a full USB 2.0 function controller, transceiver, oscillator, and UART all into a single chip, eliminating the need for numerous external components and significantly reducing development time and complexity.

Configuration is straightforward via a simple graphical user interface (GUI) configurator, allowing all customisation and operational parameters to be set without any firmware development. This makes it an ideal solution for rapid prototyping and product development. The device supports data transfer rates of up to 3 Mbaud and is fully compatible with the USB 2.0 full-speed standard.

Key Features and Benefits

• All-in-One Integration: Features an integrated USB transceiver (requiring no external resistors) and an internal clock (eliminating the need for an external crystal), simplifying PCB design and reducing the bill of materials.
• Low Power Operation: Consumes a low operating current of just 9.5mA, making it suitable for power-sensitive applications. It also includes remote wakeup functionality to resume a suspended host.
• Enhanced Connectivity: Incorporates USB Battery Charger Detection compliant with the USB BCS 1.2 specification, ensuring compatibility with a wide range of charging ports and adapters.
• Robust Performance: Operates reliably across a wide temperature range from -40°C to +85°C, ensuring stability in demanding industrial and commercial environments.

This compact interface bridge provides a reliable and cost-effective method for adding USB connectivity to microcontroller-based systems, peripherals, and various embedded applications where a simple, driver-supported serial connection is required.
