Product details
Overview
CY7C65217A-24LTXI from Infineon is a USB 2.0 Full-speed (12 Mbps) Billboard controller IC supporting native Windows 10 Billboard Device Class driver, dual-channel UART/I2C serial interface (UART up to 115.2 kbps, I2C master at 400 kHz), 9 GPIOs, and 2560 bytes of configurable flash memory. It operates across 1.71–5.5 V supply and –40°C to 105°C (automotive grade), deployed in USB Type-C dongles and docking stations requiring Alternate Mode descriptor reporting.
For engineers reviewing the CY7C65217A-24LTXI datasheet, CY7C65217A-24LTXI pinout, CY7C65217A-24LTXI application, or CY7C65217A-24LTXI equivalent, key selection factors include dual SCB support (UART + I2C), integrated 48-MHz oscillator, bus/self-powered flexibility, suspend/wakeup signaling, and automotive temperature qualification - all in a 24-pin 4.0 × 4.0 mm QFN package.
Technical Context
The CY7C65217A implements a USB Serial Interface Engine (SIE) compliant with USB 2.0 Full-speed specification and Billboard Device Class v1.21. It integrates two independent Serial Communication Blocks (SCB0 for I2C, SCB1 for UART), each with 190-byte TX/RX buffers and configurable framing (7/8 data bits, 1/2 stop bits, parity options).
Its power architecture supports both bus-powered (VBUS 3.15–5.25 V) and self-powered (VDDD 1.71–5.5 V) operation, with internal voltage regulation, dual oscillators (48 MHz for USB, 32 kHz for low-power timing), and hardware-assisted Suspend/Resume via dedicated SUSPEND and WAKEUP pins - enabling deterministic wake latency in Type-C Alternate Mode handshaking sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed | Full-speed (12 Mbps); meets USB-IF certification requirements for Billboard enumeration and descriptor reporting. |
| Serial Interfaces | Dual SCB: SCB0 as I2C master (400 kHz), SCB1 as UART (up to 115.2 kbps); enables concurrent host-to-peripheral control and status monitoring. |
| GPIO Count | 9 programmable GPIOs; supports wakeup sourcing, power sequencing control, and peripheral enable signals in compact Type-C accessories. |

| 15 | VBUS | Bus power input (3.15–5.25 V); powers internal regulator in bus-powered mode; enables VBUS detection logic. |
| 12, 24 | Power | VCCD (1.8 V core supply), VDDD (1.71–5.5 V interface supply); decoupling required per layout guidelines. |
| 8 | SUSPEND | Open-drain output indicating USB suspend state; drives external circuitry (e.g., power switches) during low-power mode. |
| 9 | WAKEUP | Input for remote wake event; triggers resume from suspend when asserted; configurable polarity via flash settings. |
Key Features
| Feature | Design Value |
|---|---|
| Native Billboard Class Support | Complies with USB Billboard Device Class v1.21; enables plug-and-play descriptor reporting to host OS without custom drivers on Windows 10+. |

Applications
| USB-C Dongles | Docking Stations |
|---|---|
Use Scenario: Compact passive adapter converting USB-C to HDMI/DisplayPort/USB-A, requiring Alternate Mode negotiation and error reporting. IC Role / Device Role / Timing Role: Billboard controller handling USB descriptor exchange and VDM (Vendor Defined Message) parsing during connection handshake. Use Value: Eliminates need for external microcontroller; reduces latency in mode negotiation via direct USB enumeration and flash-stored descriptors. |
Use Scenario: Multi-port desktop dock supporting video, data, and charging over single USB-C upstream link. IC Role / Device Role / Timing Role: Central Billboard device reporting port capabilities, cable orientation, and Alternate Mode compatibility to host OS. Use Value: Enables real-time status feedback (e.g., "DP Alt Mode not supported") without firmware development overhead. |
| Monitors with USB-C Input | Automotive Infotainment Adapters |
Use Scenario: Display with embedded USB-C upstream port that must report its DP Alt Mode capability and sink power limits. IC Role / Device Role / Timing Role: Billboard endpoint providing standardized descriptor responses to host during USB enumeration phase. Use Value: Ensures Windows/macOS correctly identifies monitor's video/audio/data roles without OEM-specific driver installation. |
Use Scenario: In-vehicle USB-C adapter connecting smartphone to head unit, supporting audio/video passthrough and diagnostics. IC Role / Device Role / Timing Role: Billboard agent communicating cable capability, power delivery contract, and fault conditions to vehicle OS. Use Value: Meets automotive thermal and reliability requirements while enabling seamless plug-and-play with mobile devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Billboard controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C65217-24LTXI | No automotive temp rating (0°C to 70°C only); lacks suspend/wakeup support; same pinout and flash size. | Restricted to commercial-grade docking accessories and consumer monitors without thermal stress. | Select when cost sensitivity outweighs extended temperature or power management needs. |
| USB2514B-AEZG | USB 2.0 hub controller with integrated Billboard functionality; requires external EEPROM for descriptors; no UART/I2C SCBs. | Used in multi-port hubs where Billboard reporting is secondary to port expansion; no peripheral interface capability. | Choose only if primary requirement is hub + Billboard combo, not standalone descriptor control with serial peripherals. |
Compared with CY7C65217-24LTXI, the A-version adds automotive temperature range and suspend/wakeup signaling - essential for thermally demanding or power-aware systems; versus USB2514B-AEZG, it trades hub functionality for integrated dual-serial control and descriptor storage, simplifying design for dedicated Billboard use cases.

FAQ
Does CY7C65217A-24LTXI require an external crystal?
No. The device integrates a factory-trimmed 48-MHz oscillator meeting USB Full-speed timing requirements, eliminating the need for an external crystal or clock source. This reduces bill-of-materials cost and PCB area while maintaining USB-IF compliance for enumeration and data transfer.
Can the UART and I2C interfaces operate simultaneously?
Yes. CY7C65217A features two independent Serial Communication Blocks (SCB0 and SCB1), allowing concurrent UART and I2C operation. Each SCB has dedicated 190-byte TX/RX buffers and configurable baud rates or clock speeds, enabling simultaneous communication with UART-based debug tools and I2C sensors or EEPROMs.
What is the role of the SUSPEND and WAKEUP pins?
SUSPEND is an open-drain output signaling USB suspend state to external circuitry (e.g., power switches), while WAKEUP is an input that triggers resume from suspend when asserted. Both are configurable in polarity and behavior via flash settings, enabling precise system-level power sequencing in battery-powered or thermally constrained Type-C accessories.
How is Billboard descriptor data stored and updated?
Descriptor data - including vendor/product IDs, language strings, and Alternate Mode definitions - is stored in the device's 2560-byte on-chip flash memory. It can be programmed via USB using Infineon's USB-Serial Configuration Utility, enabling field updates without hardware changes or external memory components.
