Product details
Overview
CY7C65210A-24LTXIT from Infineon is a USB 2.0 Full-speed (12 Mbps) Billboard controller IC designed for USB Type-C Alternate Mode negotiation and error reporting. It integrates a 48-MHz oscillator, 2560-byte configurable flash, single-channel I²C interface (400 kHz), and 11 GPIOs. It operates from 1.71 V to 5.5 V and supports commercial (0°C to 70°C) and industrial (–40°C to 85°C) temperature ranges in a 24-pin QFN (4.0 mm × 4.0 mm, 0.5-mm pitch) package, targeting USB-C dongles and docking stations.
For engineers reviewing the CY7C65210A-24LTXIT datasheet, CY7C65210A-24LTXIT pinout, CY7C65210A-24LTXIT application, or CY7C65210A-24LTXIT equivalent, key selection criteria include Billboard Device Class v1.21 compliance, integrated USB termination, bus/self-powered flexibility, suspend/wakeup omission (vs. CY7C65210), and I²C master timing constraints.
Technical Context
The CY7C65210A implements the USB Billboard Device Class specification v1.21 to report USB Type-C Alternate Mode failures (e.g., DisplayPort or Thunderbolt mode rejection) to host OS via standardized descriptors. It uses its internal 48-MHz oscillator for USB timing and supports native Windows 10 Billboard driver stack without custom firmware.
Unlike the legacy CY7C65210, the CY7C65210A removes SUSPEND and WAKEUP pin functionality-pins 8 and 9 are repurposed as GPIO_12 and GPIO_13-simplifying power management in systems where host-controlled suspend is unnecessary. Its single I²C interface (SCL/SDA on pins 21/22) communicates with upstream controllers to fetch billboard descriptors stored in flash.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed | Full-speed (12 Mbps); meets USB 2.0 certification for reliable Billboard descriptor exchange over standard USB-C cables. |
| I²C Interface | Single master, up to 400 kHz; enables direct connection to microcontroller or PMIC for dynamic descriptor updates without external level shifters. |
| GPIO Count | 11 programmable pins; supports status signaling, mode selection, and hardware handshaking in compact USB-C accessories. |
| Flash Memory | 2560 bytes; stores Billboard-specific descriptors (bcdVersion, wVendorCode, iErrorMessage) persistently across power cycles. |
| Supply Range | 1.71 V to 5.5 V; allows direct VBUS (3.15–5.25 V) or regulated 1.8/3.3 V rail operation without external LDO. |
| ESD Protection | 2.2 kV HBM; protects USB data lines (USBDP/USBDM) and GPIOs against electrostatic discharge during hot-plug events. |
| Package | 24-lead QFN (4.0 mm × 4.0 mm, 0.5-mm pitch); enables high-density PCB layout in space-constrained dongles and adapters. |
Pinout & Package
Package: 24-lead QFN (4.0 mm × 4.0 mm, 0.5-mm pitch, 0.55-mm height), RoHS-compliant, with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–6, 19–23 | GPIO | 11 general-purpose I/Os (GPIO_1 to GPIO_11, GPIO_12, GPIO_13); all tristate-capable except GPIO_1 (input-only wakeup source). |
| 10, 11 | USBIO | USBDP/USBDM differential pair with integrated 1.5-kΩ pull-up (USBDP) and 27-Ω series termination; eliminates external USB resistors. |
| 14 | Reset | nXRES: active-Low asynchronous reset; internally pulled up, can be left floating if unused. |
| 15, 24 | Power | VBUS (3.15–5.25 V) and VDDD (1.71–5.5 V); supports dual-supply or single-supply configurations with internal regulator. |
| 21, 22 | I²C | SCB_1/GPIO_3 (SCL) and SCB_2/GPIO_4 (SDA); dedicated I²C master interface for descriptor loading from external EEPROM or MCU. |
Key Features
| Feature | Design Value |
|---|---|
| Billboard Device Class v1.21 | Enables standardized error reporting for USB-C Alternate Mode failures (e.g., "DisplayPort mode not supported") without custom driver development. |
| Integrated 48-MHz Oscillator | Eliminates external crystal and load capacitors, reducing BOM count and board area in cost-sensitive accessories. |
| Configurable Flash (2560 B) | Stores vendor-specific descriptors (wVendorCode, iErrorMessage) and supports field updates via I²C without reprogramming firmware. |
| USB Termination Resistors | On-die 27-Ω series (USBDP/USBDM) and 1.5-kΩ pull-up (USBDP) meet USB 2.0 electrical compliance without external components. |
| Wide Supply Range (1.71–5.5 V) | Operates directly from VBUS or low-voltage rails, enabling single-rail designs in battery-powered or automotive USB-C interfaces. |
Applications
| Dongle Adapter | Docking Station |
|---|---|
Use Scenario: USB-C to HDMI/DisplayPort adapter that fails to enter Alternate Mode due to cable or sink incompatibility. IC Role / Device Role / Timing Role: Billboard controller enumerates as USB device to report failure reason (e.g., "Invalid VCONN Power") via standardized descriptors. Use Value: Enables immediate user feedback ("Check cable") instead of silent mode failure, improving end-user experience and reducing support calls. | Use Scenario: Multi-port USB-C dock negotiating simultaneous DisplayPort, USB 3.2, and PD contracts with host laptop. IC Role / Device Role / Timing Role: Monitors USB-C CC line negotiations and reports Alternate Mode rejection events to host OS within <100 ms of detection. Use Value: Provides deterministic error visibility during complex multi-protocol handshakes, accelerating debug and validation of dock firmware. |
| USB-C Monitor | Automotive Infotainment Hub |
Use Scenario: USB-C monitor with embedded USB hub and DisplayPort Alt Mode that rejects video handshake due to bandwidth mismatch. IC Role / Device Role / Timing Role: Acts as Billboard endpoint on separate USB interface, delivering iErrorMessage string to Windows Event Log. Use Value: Allows OEMs to log root-cause diagnostics remotely via Windows telemetry, supporting predictive maintenance and firmware updates. | Use Scenario: In-vehicle USB-C port supporting smartphone mirroring (Android Auto/CarPlay) and charging, rejecting Alt Mode due to thermal throttling. IC Role / Device Role / Timing Role: Reports "Thermal Limit Exceeded" via bcdVersion=0x0121 and vendor-defined wVendorCode to head unit OS. Use Value: Enables graceful fallback to USB 2.0 data + charging only, preserving core functionality while alerting driver via dashboard UI. |
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 | Includes SUSPEND/WAKEUP pins; Billboard spec v1.1; 9 GPIOs; same QFN-24 package. | Required where host-initiated suspend/resume coordination is needed (e.g., low-power portable docks). | Select CY7C65210 if system-level power sequencing mandates hardware suspend signaling; otherwise CY7C65210A reduces GPIO routing complexity. |
| USB2514B-AEZG | USB 2.0 hub controller with optional Billboard descriptor support via external EEPROM; no integrated flash or oscillator. | Used when Billboard function is secondary to hub functionality; requires additional firmware and external memory. | Choose USB2514B only if existing design already uses it as hub and can allocate GPIOs/EEPROM for Billboard emulation. |
Compared with CY7C65210-24LTXI, CY7C65210A-24LTXIT trades suspend/wakeup capability for two extra GPIOs and updated Billboard v1.21 compliance-ideal for fixed-function accessories. Versus USB2514B-AEZG, it delivers turnkey Billboard operation with zero external components, simplifying certification and reducing layout risk.

FAQ
Does CY7C65210A-24LTXIT require an external crystal?
No. The device integrates a factory-trimmed 48-MHz oscillator meeting USB 2.0 Full-speed timing accuracy requirements (±0.25%). This eliminates the need for external crystals, load capacitors, or clock buffers, reducing BOM cost and PCB area in USB-C accessories.
How is Billboard descriptor content programmed into CY7C65210A-24LTXIT?
Descriptors are written to the 2560-byte internal flash via the I²C interface using Infineon's USB-Serial Configuration Utility. The utility generates binary images containing bcdVersion, wVendorCode, and iErrorMessage fields, which are loaded during manufacturing or field update without firmware compilation.
Can CY7C65210A-24LTXIT operate in bus-powered mode only?
Yes. It supports both bus-powered (VBUS = 3.15–5.25 V) and self-powered (VDDD = 1.71–5.5 V) configurations. In bus-powered mode, VDDD is internally regulated from VBUS; no external regulator is required unless system-level noise isolation is critical.
What is the functional difference between CY7C65210A and CY7C65217A?
CY7C65210A provides a single I²C interface and 11 GPIOs, while CY7C65217A adds a dual UART/I²C interface (supporting RS-232/RS-422) but reduces GPIO count to 9. Choose CY7C65210A for pure Billboard + I²C control; select CY7C65217A when serial debug or legacy peripheral bridging is required alongside Billboard.
