Overview

The CY7C65211-24LTXI is a highly integrated USB-Serial bridge controller that supports Full-Speed USB 2.0. It provides a flexible interface to convert USB traffic into UART, I2C, or SPI protocols, and includes 10 GPIO pins for additional system control.

Why Choose This Part

This controller eliminates the need for external USB termination resistors and features an integrated voltage regulator supporting a wide supply range from 1.71V to 5.5V. It stands out by offering both serial bridging and integrated CAPSENSE touch-sensing capabilities in a single 24-QFN package.

Applications

USB-to-UART/I2C/SPI Bridges
Providing a simple communication interface between a PC and embedded microcontrollers or sensors using standard serial protocols.
Capacitive Touch Sensing
Utilizing integrated CAPSENSE technology with smart sensing algorithms for buttons or sliders in consumer interfaces.
Battery Powered Devices
Leveraging Battery Charger Detection (BCD) Rev. 1.2 to identify power sources and manage charging states via USB.

Getting Started

Developers can use the Infineon USB-Serial Configuration Utility to program the internal 512-byte flash for customized VID/PID and interface settings. For hardware evaluation, check for the CYUSBSERV-CP kit or compatible breakout boards that support the 24-QFN footprint.

Also Consider

CP2102N SiLSilicon Labs - A very popular and smaller alternative if only high-speed UART bridging is required without I2C or SPI support.
FT232H FTDI Chip - Supports High-Speed USB (480 Mbps) and multi-protocol synchronous serial engines (MPSSE) for faster data throughput.
MCP2221A MCHPMicrochip Technology - Provides a similar USB-to-UART/I2C bridge functionality with a dedicated HID interface that does not require custom drivers.
