CY7C65217-24LTXIT

Controllers Overview

The CY7C65217-24LTXIT is a USB Billboard controller from Infineon Technologies, designed for Type-C device containers supporting Alternate Modes. It implements the USB Billboard Device Class Rev. 1.1 and operates at Full-Speed (12 Mbps). The component features dual-channel serial communication blocks supporting UART and I2C interfaces, alongside seven configurable GPIO pins. It includes an integrated 48-MHz oscillator, voltage regulator, and 2560 bytes of configurable flash memory for storing descriptors. Operating within an industrial temperature range of -40°C to +85°C, it supports bus-powered configurations with suspend and resume capabilities.

Controllers Feature Summary

• Supports native Billboard Device Class Driver for communicating Alternate Modes to USB Host systems via BOS descriptors.
• Integrates dual Serial Communication Blocks enabling simultaneous UART and I2C interface operations.
• Features internal 48-MHz clocking and configurable flash memory for customizing VID, PID, and string descriptors.
• Provides low-power management through USB Suspend mode with remote wakeup support.

Controllers Applications

• Dongles for Type-C devices
• Docking stations
• Monitors

Controllers Procurement Notes

Verify the specific suffix LTXIT against the manufacturer's ordering guide to confirm package type and tape/reel specifications. Ensure the design accounts for the Industrial temperature grade (-40°C to +85°C) requirements. Confirm that the host system supports the Billboard Device Class Rev. 1.1 specification for proper enumeration.

Controllers Selection Notes

Select this model when dual serial interfaces are required for Type-C Alternate Mode signaling. Compare against the CY7C65217A if Billboard Rev. 1.21 compliance or additional GPIOs are necessary. Verify power supply constraints, as VDDD ranges from 1.71 V to 5.5 V while VCCD requires decoupling near 1.8 V.

Controllers Part Context

This component belongs to the EZ-USB™ Serial Bridge Controller family, specifically optimized for Billboard functionality. It shares architectural similarities with the CY7C65210 but distinguishes itself through the inclusion of a second serial communication block for UART/I2C connectivity, facilitating more complex peripheral integration in Type-C applications.
