USB2SERA11CFK Description

Short technical summary and product information.

The NXP Semiconductors USB2SERA11CFK is a versatile USB to UART bridge controller designed for embedded systems. This single-chip solution simplifies the integration of a UART port into systems requiring USB connectivity, reducing external component counts. It complies with USB 2.0 full-speed specifications (12 Mbps) and supports both TTL RS232 and RS485 UART interfaces.

 

The device offers user-programmable custom baud rates ranging from 300 bps to 115200 bps. It supports standard UART data formats, including 8-bit data, 1 or 2 stop bits, and configurable parity (odd, even, or none). Flow control options include hardware (RTS/CTS) and software (Xon/Xoff) methods. The USB2SERA11CFK also features wake-up and suspend signals, an integrated 3.3V regulator for USB IO, and an integrated Power-On-Reset circuit.

 

This controller is compatible with UHCI, OHCI, and EHCI host controllers. It operates on a single supply voltage from 3V to 5V and has a configurable internal flash for USB VID, PID, and device description strings, along with password protection. The USB2SERA11CFK is supplied in a 24-pin QFN package, measuring 5x5 mm, with an exposed pad for enhanced thermal performance.
