Product details
Overview
CY7C65217-24LTXI from Infineon is a USB 2.0 Full-speed (12 Mbps) Billboard controller IC for USB Type-C Alternate Mode devices, featuring dual-channel UART/I2C serial interfaces, 7 GPIOs, integrated 48-MHz oscillator, and 2560-byte configurable flash memory. It supports bus- or self-powered operation across 1.71–5.5 V and operates from –40°C to 85°C (industrial grade), targeting docking stations and Type-C dongles.
For engineers reviewing the CY7C65217-24LTXI datasheet, CY7C65217-24LTXI pinout, CY7C65217-24LTXI application, or CY7C65217-24LTXI equivalent, key selection criteria include dual UART/I2C channel support, native Windows 10 Billboard Device Class driver compatibility, suspend/wakeup signaling, and QFN-24 package integration with embedded USB termination resistors.
Technical Context
The CY7C65217 implements a dedicated USB Billboard Device Class stack compliant with USB Type-C specification v1.1, enumerating as a Billboard device upon connection to host systems. Its dual SCB (Serial Communication Block) units operate independently: SCB0 as I2C master (up to 400 kHz), SCB1 as UART (up to 115200 bps, 7/8 data bits, configurable parity/framing).
Internal resources include a 48-MHz oscillator for USB timing and system clocking, a 32-kHz oscillator for low-power suspend/resume control, and a voltage regulator supporting VBUS (3.15–5.25 V) input with VDDD core supply (1.71–5.5 V). Suspend mode reduces current draw while retaining configuration state in flash.

| 4, 5 | UART Interface | SCB1_0/GPIO_8 (RXD) and SCB1_1/GPIO_9 (TXD): full-duplex UART supporting 115200 bps and hardware flow control |
Key Features
| Feature | Design Value |
|---|---|
| Native Billboard Device Class Support | Pre-certified USB 2.0 Billboard enumeration per USB Type-C spec v1.1; zero-driver required on Windows 10+ hosts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Billboard controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C65210-24LTXI | Single-channel I2C only; 9 GPIOs; lacks UART interface and SCB1 peripheral | Targeted at simpler Type-C accessories where serial debug or sensor bridging is unnecessary | Select when cost sensitivity outweighs need for dual-protocol flexibility and debug channel isolation |
| CY7C65217A-24LTXI | Same pinout and peripherals, but excludes suspend/wakeup support per datasheet Table 1 note [2] | Intended for always-on or externally managed power systems where autonomous wake-from-suspend is not required | Choose for fixed-function docks or monitors with external power sequencing and no low-power idle requirement |
Compared with CY7C65210-24LTXI, the CY7C65217-24LTXI adds UART-based diagnostics and peripheral bridging; compared with CY7C65217A-24LTXI, it retains autonomous suspend/wakeup control critical for battery-backed or portable Type-C accessories.

FAQ
Does CY7C65217-24LTXI require an external crystal?
No. The device integrates a factory-trimmed 48-MHz oscillator optimized for USB Full-speed timing accuracy, eliminating the need for an external crystal or resonator. This reduces BOM count, PCB area, and startup time while maintaining ±0.25% frequency tolerance over temperature and voltage.
Can the UART and I2C interfaces operate simultaneously?
Yes. CY7C65217 features two independent Serial Communication Blocks (SCBs): SCB0 configured as I2C master and SCB1 as UART. They share no hardware resources and can transmit/receive concurrently - for example, polling an I2C temperature sensor while streaming debug logs over UART.
How is Billboard descriptor content programmed?
Descriptors are stored in the internal 2560-byte flash memory and programmed using Infineon's USB-Serial Configuration Utility (USBUARTConfig.exe) via USB. No JTAG or external programmer is needed; changes persist across power cycles and support field updates without hardware modification.
What is the function of the SUSPEND and WAKEUP pins?
SUSPEND (Pin 8) is an output that asserts during USB suspend mode (active-HIGH by default, configurable); WAKEUP (Pin 9) is an input that triggers resume from suspend when asserted. Both support polarity inversion via flash configuration, enabling compatibility with host-side power management logic.
