USB2SERA10CFK

Controllers Overview

The USB2SERA10 is a single-chip USB to UART bridge controller designed for embedded systems. It supports USB 2.0 full-speed operation at 12 Mbps and interfaces with TTL RS232 or RS485 UARTs. The device operates on a single 3 V to 5 V supply and integrates an internal 3.3 V regulator, power-on-reset circuit, and clock multiplier PLL supporting external crystals from 2 MHz to 16 MHz. It features user-programmable baud rates ranging from 300 bps to 115200 bps, configurable parity and stop bits, and hardware or software flow control options.

Controllers Feature Summary

• Integrates USB 2.0 full-speed transceiver and UART engine in a compact QFN package
• Supports RS232 and RS485 communication with configurable flow control
• Includes internal voltage regulator and automatic crystal frequency detection
• Allows customization of VID, PID, and product strings via software tool

Controllers Applications

• Embedded systems requiring USB connectivity for legacy serial devices
• Industrial controllers and modems interfacing with modern USB hosts
• Console cables for computer-to-device serial communication

Controllers Procurement Notes

Verify the component status as this datasheet indicates advance information subject to change. Confirm the specific ordering suffix matches the required package and temperature range. Ensure compatibility with the provided configuration GUI for VID/PID customization if custom identifiers are needed.

Controllers Selection Notes

Select this component when a low-cost, single-chip solution is required to bridge USB 2.0 full-speed buses to UART interfaces. Consider the integrated 3.3 V regulator and clock PLL to minimize external component count. Verify that the operating voltage range of 2.7 V to 5.5 V aligns with the system power design.

Controllers Part Context

This part belongs to the Freescale Ready Play Solutions family, which integrates certified functions to reduce development costs. The USB2SER series simplifies design cycles by providing a pre-certified USB to UART bridge, eliminating the need for complex discrete designs or custom driver development for basic CDC functionality.
