CY7C65217-24LTXI

Controllers Overview

The CY7C65217-24LTXI is a USB Billboard controller 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, including a UART interface supporting up to 115200 bps and an I2C master interface up to 400 kHz. It integrates a 48-MHz oscillator, voltage regulators, and 2560 bytes of configurable flash memory for storing descriptors. The device supports bus-powered or self-powered configurations with operating voltages ranging from 1.71 V to 5.5 V and includes ESD protection rated at 2.2 kV HBM.

Controllers Feature Summary

• Native support for USB Billboard Device Class Rev. 1.1 for communicating Alternate Mode capabilities to host systems
• Dual-channel Serial Communication Blocks enabling simultaneous UART and I2C interface operations
• Integrated internal oscillators providing 48 MHz and 32 kHz clock sources without external components
• Configurable GPIOs and power control signals for managing peripheral states during suspend modes

Controllers Applications

• USB Type-C dongles requiring Billboard device support
• Docking stations and hubs displaying Alternate Mode information
• Monitors and displays connected via USB Type-C interfaces
• Automotive infotainment systems utilizing USB-C connections

Controllers Procurement Notes

Verify the specific revision suffix and package type against the manufacturer's current ordering guide. Confirm that the industrial temperature range requirements align with the -40°C to +85°C specification. Ensure compatibility with the USB Billboard Device Class Rev. 1.1 standard required by the target application. Check for any specific configuration utility dependencies for programming the internal flash memory.

Controllers Selection Notes

Select this model when dual-channel serial communication is required alongside Billboard functionality. The CY7C65217 provides both UART and I2C interfaces, unlike the single-channel CY7C65210. Consider the CY7C65217A variant if USB Billboard Device Class Rev. 1.21 support is necessary. Verify GPIO count requirements as this model offers seven configurable pins compared to nine in other variants.

Controllers Part Context

This component belongs to the CY7C6521x family of USB Billboard controllers manufactured by Infineon Technologies. It shares the same QFN-24 package and core architecture with the CY7C65210, CY7C65210A, and CY7C65217A. The primary distinction lies in its dual-channel serial communication capability and compliance with Billboard specification version 1.1.

Controllers Replacement Considerations

CY7C65217A-24LTXI: Offers updated Billboard specification Rev. 1.21 support while maintaining similar pinout and functionality.
