Overview

The CY7C65215-32LTXI is a highly integrated USB-Serial bridge controller that supports dual-channel communication for UART, I2C, and SPI protocols. It features integrated USB termination resistors and Battery Charger Detection (BCD) compliant with USB-BC v1.2, reducing external component count and simplifying power management. The device also includes CapSense technology for touch-sensing applications and a JTAG master for peripheral programming.

Why Choose This Part

This bridge supports a wide operating voltage range from 1.71V to 5.5V and consumes only 5uA in sleep mode, making it suitable for battery-powered designs. It provides 17 GPIO pins and integrated USB termination, significantly reducing PCB footprint compared to discrete multi-chip solutions.

Applications

Industrial Dual-Channel Bridging
Connecting two independent serial interfaces (UART/I2C/SPI) to a single USB host for multi-sensor or multi-controller management.
USB Battery Charging
Utilizing integrated BCD to detect power sources and manage charging profiles in portable electronic devices.
Capacitive Touch Interfaces
Implementing user input controls through CapSense buttons or sliders while maintaining USB connectivity.
Embedded System Debugging
Using the JTAG master functionality to program or debug downstream microcontrollers via the USB interface.
