Product details
Overview
CY7C65210-24LTXI from Infineon is a USB 2.0 Full-speed (12 Mbps) Billboard controller IC that implements the USB Type-C Billboard Device Class v1.1, integrates a 48-MHz oscillator, 2560-byte configurable flash, and single-channel I²C interface (up to 400 kHz), with 9 GPIOs and native Windows 10 driver support - deployed in USB-C dongles and docking stations for Alternate Mode error reporting.
For engineers reviewing the CY7C65210-24LTXI datasheet, CY7C65210-24LTXI pinout, CY7C65210-24LTXI application, or CY7C65210-24LTXI equivalent, key selection criteria include Billboard Class compliance, integrated USB termination, bus/self-powered operation, suspend/wakeup signaling, and QFN-24 package compatibility with USB-C system-level firmware update paths.
Technical Context
The CY7C65210-24LTXI implements the USB Billboard Device Class specification v1.1, enumerating as a standard USB HID-compliant device with dedicated descriptors for Alternate Mode failure reporting. It uses an internal 48-MHz oscillator for USB timing and supports both bus-powered (VBUS 3.15–5.25 V) and self-powered (VDDD 1.71–5.5 V) configurations.
Its serial communication block provides a single I²C master interface (SCL/SDA on pins 21/22) with 190-byte TX/RX buffers and configurable GPIO mapping. Suspend/Wakeup functionality is implemented via dedicated SUSPEND (pin 8) and WAKEUP (pin 9) signals, with active-low/high polarity programmable via flash configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
Package: 24-pin QFN (4.0 mm × 4.0 mm, 0.5-mm pitch), exposed thermal pad, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–2, 4–6, 20, 23 | GPIO | Tristate digital I/Os (GPIO_6 through GPIO_10, GPIO_2, GPIO_5); configurable as input/output with pull-up/down options. |
| 7 | GPIO / POWER# | Power-good indicator output (CY7C65210) - asserts low when VDDD is stable; not present on CY7C65210A variant. |

| 15 | VBUS | Input sensing VBUS (3.15–5.25 V) for bus-powered operation and overvoltage protection monitoring. |
| 19 | GPIO_1 | Input-capable GPIO usable as secondary wake-up source - complements pin 9 for multi-trigger suspend recovery. |
| 21–22 | SCL / SDA | I²C master interface pins - connect directly to host MCU's I²C bus; support standard and fast-mode timing. |
| 24 | VDDD | Main supply for core logic and I/O - accepts 1.71–5.5 V; requires local 1 µF decoupling to VSSD. |
Key Features
| Feature | Design Value |
|---|---|
| Native Billboard Class Support | Enumerates as USB HID-compliant Billboard device with pre-defined descriptors - eliminates need for custom driver development on Windows 10+. |
| Integrated USB Termination | On-die 27-Ω series resistors on USBDP/USBDM and 1.5-kΩ pull-up on USBDP - removes four external components and improves signal integrity. |
| Configurable Suspend/Wakeup | Dedicated SUSPEND output and dual-input WAKEUP (pins 8 & 9) with polarity and trigger-edge programmability - enables precise power-state coordination with host system. |
| Nonvolatile Flash Storage | 2560-byte flash memory retains Billboard descriptors, vendor ID, product ID, and custom strings across power cycles - simplifies field updates and variant management. |
| Wide Input Voltage Range | VDDD operates from 1.71 V to 5.5 V - supports direct interfacing with 1.8 V, 3.3 V, and 5 V microcontrollers without level shifters. |
Applications
| Dongle Systems | Docking Stations |
|---|---|
|
Use Scenario: USB-C to HDMI/DisplayPort adapter fails during Alternate Mode negotiation due to cable or sink incompatibility. IC Role / Device Role / Timing Role: Billboard controller captures and reports standardized error codes (e.g., "Incompatible Cable") via USB HID interface. Use Value: Enables immediate user-facing notification on host OS instead of silent link failure - reduces support calls and improves UX. |
Use Scenario: Multi-port USB-C dock experiences mode-switching conflict between Thunderbolt and DisplayPort Alt Mode. IC Role / Device Role / Timing Role: Acts as authoritative Billboard endpoint, asserting correct descriptor set based on negotiated mode and port status. Use Value: Prevents host OS confusion by delivering deterministic, spec-compliant error reporting - ensures consistent behavior across Windows/macOS/Linux. |
| Monitors with USB-C Uplink | Automotive USB-C Infotainment |
|
Use Scenario: Monitor with USB-C upstream port fails to enter DisplayPort Alt Mode due to insufficient power delivery handshake. IC Role / Device Role / Timing Role: Monitors VBUS and USB enumeration sequence; generates Billboard report upon PD contract mismatch or mode rejection. Use Value: Delivers actionable diagnostics (e.g., "Insufficient Power for Alt Mode") directly to OS UI - accelerates root-cause identification. |
Use Scenario: In-vehicle infotainment system with USB-C media port rejects smartphone connection due to unsupported Alternate Mode request. IC Role / Device Role / Timing Role: Intercepts USB descriptor requests and returns Billboard response with automotive-grade temperature range (-40°C to 105°C) compliance. Use Value: Meets AEC-Q200-aligned thermal requirements while providing standardized error visibility - satisfies OEM diagnostic logging mandates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Billboard controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C65210A-24LTXI | 11 GPIOs (vs. 9), no POWER# pin, no suspend/wakeup support - removed per Billboard spec v1.21 optimization. | Targeted at cost-sensitive, non-suspend designs where power-state signaling is unnecessary. | Select when flash-based descriptor updates are required but system-level suspend coordination is handled externally. |
| CY7C65217-24LTXI | Dual UART/I²C interface (vs. single I²C), 7 GPIOs, retains suspend/wakeup - adds serial debug path but reduces GPIO count. | Suitable for systems requiring UART-based firmware updates or legacy serial diagnostics alongside Billboard function. | Choose when concurrent UART debug access and Billboard reporting are needed, accepting trade-off in GPIO availability. |
Compared with CY7C65210A-24LTXI, the CY7C65210-24LTXI provides suspend/wakeup signaling essential for power-aware USB-C systems; versus CY7C65217-24LTXI, it offers higher GPIO count and simpler I²C-only integration at the expense of UART capability.

FAQ
Does CY7C65210-24LTXI require an external crystal or oscillator?
No. The device integrates a factory-trimmed 48-MHz internal oscillator qualified for USB Full-speed timing compliance. No external crystal, resonator, or clock source is needed - reducing BOM count and PCB area while maintaining ±0.25% frequency accuracy over temperature and voltage.
Can the I²C interface operate above 400 kHz?
No. The I²C master interface is specified up to 400 kHz (Fast Mode) only. Attempting higher frequencies violates timing margins and may cause communication failures. The 190-byte TX/RX buffers and register-mapped SCB ensure reliable operation within this limit under all supported VDDD conditions.
How is the Billboard descriptor content updated in the 2560-byte flash?
Descriptors are programmed using Infineon's USB-Serial Configuration Utility (USBCONFIG) via USB interface. The utility writes vendor ID, product ID, device class descriptors, and custom strings into flash; no JTAG or SWD programming is required, enabling field updates without hardware rework.
Is CY7C65210-24LTXI compatible with USB-C cables that lack E-Marker chips?
Yes. The device operates independently of cable E-Marker presence. It reports errors related to Alternate Mode negotiation (e.g., "Invalid Mode Request") regardless of cable intelligence - functioning as a system-level Billboard endpoint that interprets and relays USB-C protocol-level failures to the host OS.
