Product details
Overview
CY7C65210-24LTXIT from Infineon Technologies is a USB 2.0 Full-speed (12 Mbps) Billboard controller IC that natively implements the USB Billboard Device Class (spec v1.1), integrates a 48-MHz oscillator, 2560-byte configurable flash, and single-channel I²C interface operating up to 400 kHz with 190-byte TX/RX buffers. It provides 9 GPIOs, supports bus- or self-powered operation across 1.71–5.5 V, and targets USB Type-C Alternate Mode containers such as docking stations.
For engineers reviewing the CY7C65210-24LTXIT datasheet, CY7C65210-24LTXIT pinout, CY7C65210-24LTXIT application, or CY7C65210-24LTXIT equivalent, key selection criteria include native Windows 10 Billboard driver support, integrated USB termination and pull-up resistors, suspend/wakeup signaling capability, and QFN-24 (4.0 × 4.0 mm) package compatibility with industrial temperature range (–40°C to 85°C).
Technical Context
The CY7C65210-24LTXIT implements a dedicated USB Serial Interface Engine (SIE) compliant with USB 2.0 Full-speed signaling and Billboard Device Class v1.1 descriptors. It embeds dual oscillators - a 48-MHz main clock for USB timing and a 32-kHz auxiliary clock for low-power suspend/resume control - and uses internal voltage regulation to support both VBUS-powered (3.15–5.25 V) and core-supplied (1.71–5.5 V) configurations.
Its serial communication block supports only I²C master mode (no UART), with SCL/SDA routed to pins 21/22 (SCB_1/GPIO_3 and SCB_2/GPIO_4). The device stores vendor-defined Billboard descriptors and configuration in 2560 bytes of on-chip flash memory, enabling field-updatable behavior without external EEPROM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed | Full-speed at 12 Mbps - meets USB 2.0 compliance for Billboard enumeration without external transceiver. |
| Billboard Spec | USB Billboard Device Class v1.1 - enables native Windows 10 driver support and standardized error reporting for Type-C Alternate Mode failures. |
| I²C Interface | Single master, up to 400 kHz - connects to upstream microcontroller or PMIC for descriptor updates and status polling. |
| GPIO Count | 9 programmable pins - includes dedicated SUSPEND (pin 8) and WAKEUP (pin 9) signals for power-state coordination. |
| Flash Memory | 2560 bytes - stores Billboard descriptors, vendor ID/product ID, and alternate mode error strings; non-volatile and reprogrammable. |
| Operating Voltage | 1.71 V to 5.5 V (VDDD) - allows direct connection to 3.3 V or 5 V logic domains without level shifters. |
| Temperature Range | –40°C to +85°C - qualified for industrial-grade USB-C dock and monitor applications. |
Pinout & Package
Package: 24-lead QFN (4.0 mm × 4.0 mm, 0.5-mm pitch, 0.55-mm height), RoHS-compliant, exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 10, 11 | USBDP / USBDM | Integrated USB 2.0 differential pair with 1.5-kΩ pull-up on USBDP and on-chip 27-Ω termination - eliminates external resistors. |
| 14 | nXRES | Active-low asynchronous reset - ties to system reset rail or left floating with internal pull-up if unused. |
| 15 | VBUS | Input sensing and power source - monitors host VBUS presence (3.15–5.25 V) for bus-powered mode detection. |
| 21, 22 | SCB_1/GPIO_3, SCB_2/GPIO_4 | I²C SCL/SDA - dedicated hardware interface for descriptor configuration and status readback; not software-bitbanged. |
| 8 | SUSPEND | Output signal indicating USB suspend state - configurable active-HIGH/LOW via flash settings; used to gate downstream power rails. |
| 9 | WAKEUP | Input trigger for remote wake - responds to edge transitions during suspend to initiate USB resume handshake. |
Key Features
| Feature | Design Value |
|---|---|
| Native Billboard Class Support | Complies with USB Billboard Device Class v1.1 - enables plug-and-play Windows 10/11 recognition without custom drivers. |
| Integrated USB Termination | On-die 27-Ω series resistors on USBDP/USBDM and 1.5-kΩ pull-up on USBDP - reduces BOM count and layout complexity. |
| Configurable Flash Memory | 2560-byte non-volatile storage - holds vendor-specific descriptors, error messages, and alternate mode identifiers for field updates. |
| Dual Oscillator Architecture | 48-MHz main clock for USB timing + 32-kHz low-power clock for suspend/resume - enables sub-100 µA deep-suspend current. |
| Flexible Power Modes | Supports bus-powered (VBUS-derived) and self-powered (VDDD-supplied) operation - simplifies power architecture in Type-C accessories. |
Applications
| Docking Station | USB-C Monitor |
|---|---|
|
Use Scenario: A multi-port USB-C dock negotiates DisplayPort Alt Mode but fails due to cable or sink incompatibility. IC Role / Device Role / Timing Role: Billboard controller detects Alt Mode rejection, retrieves pre-stored error descriptor from flash, and presents human-readable failure reason to OS. Use Value: Eliminates "black screen" ambiguity by delivering precise error context (e.g., "DP Alt Mode rejected: Sink does not support HBR2") via standard USB interface. |
Use Scenario: A USB-C monitor with embedded USB hub and audio DAC requires fallback notification when video link training fails. IC Role / Device Role / Timing Role: Acts as Billboard endpoint during USB enumeration; intercepts and reports UFP-side Alt Mode handshake failures before display initialization. Use Value: Enables OS-level alert (e.g., Windows Action Center notification) instead of silent video initialization timeout. |
| Automotive USB-C Adapter | Type-C Dongle |
|
Use Scenario: In-vehicle infotainment system uses USB-C for smartphone mirroring but encounters incompatible phone firmware. IC Role / Device Role / Timing Role: Monitors USB control transfers during Alt Mode discovery; triggers SUSPEND output to disable power-hungry DP PHY upon persistent NAK. Use Value: Reduces standby current by >80% during failed negotiation while maintaining USB enumeration visibility. |
Use Scenario: Passive USB-C to HDMI dongle must report "HDMI not supported" when connected to a laptop lacking DP Alt Mode. IC Role / Device Role / Timing Role: Emulates Billboard device during USB attach; serves static descriptor indicating unsupported alternate modes based on VID/PID match. Use Value: Prevents OS from attempting unsupported video handshakes, avoiding display driver crashes or timeout hangs. |
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-24LTXIT | 11 GPIOs (vs. 9), no suspend/wakeup support - removes SUSPEND/WAKEUP pins; adds two extra GPIOs. | Targeted at static Billboard implementations where power-state coordination is handled externally. | Select when additional GPIOs are required and suspend/wakeup signaling is unnecessary. |
| CY7C65217-24LTXIT | Dual UART/I²C interface (vs. single I²C); 7 GPIOs; retains suspend/wakeup; same Billboard spec v1.1. | Suitable for systems requiring serial debug or legacy peripheral bridging alongside Billboard functionality. | Select when UART-based host communication (e.g., MCU debug console) is needed in parallel with Billboard operation. |
Compared with CY7C65210A-24LTXIT and CY7C65217-24LTXIT, the CY7C65210-24LTXIT uniquely balances GPIO count, suspend/wakeup signaling, and I²C-only serial interface - making it optimal for cost-sensitive, power-aware USB-C accessories where UART is unnecessary and extra GPIOs are not required.

FAQ
Does CY7C65210-24LTXIT require an external crystal?
No. The device integrates a factory-trimmed 48-MHz oscillator sufficient for USB Full-speed timing compliance, plus a 32-kHz oscillator for suspend/resume control. No external crystal or resonator is needed, reducing BOM cost and PCB area.
Can the Billboard descriptors be updated after soldering?
Yes. Descriptors are stored in 2560 bytes of on-chip flash memory and can be rewritten over USB using Infineon's USB-Serial Configuration Utility. Updates do not require JTAG or external programming hardware.
What is the function of the Debug I/O pin (pin 18)?
Pin 18 is a dedicated debug port used internally during factory programming and qualification. It is not user-accessible in normal operation and must be left floating per datasheet guidance; connecting it may disrupt device initialization.
Is CY7C65210-24LTXIT compatible with USB-C cables that lack VCONN power?
Yes. The device operates in bus-powered mode using VBUS (pin 15) and does not require VCONN. Its Billboard functionality is independent of VCONN presence, making it compatible with all USB-C cables including passive and unpowered variants.
