CY7C65210-24LTXIT - USB 2.0 Billboard Controller | Infineon
部品番号: CY7C65210-24LTXIT ✓ 生産中CY7C65210-24LTXIT 概要
A USB Billboard controller is a dedicated USB interface IC used to expose device capabilities and control information to a USB host. Within the interface-controller hierarchy, it sits between a USB device controller and an embedded peripheral that requires enumeration, configuration, or serial connectivity. The CY7C65210 family combines USB full-speed signaling with I2C, UART, GPIOs, flash memory, and integrated USB termination resistors.
The controller supports USB 2.0 full-speed operation at 12 Mbps and includes native Billboard Device Class Driver support. Its single-channel I2C interface operates as a master up to 400 kHz. Separate transmit and receive buffers provide 190 bytes each, allowing protocol data and short command sequences to be buffered between the USB host and the connected peripheral.
The CY7C65210-24LTXIT also integrates programmable GPIO functions and flash memory for configuration storage. Integrated USB termination resistors reduce the number of external USB signal-conditioning components, while UART connectivity provides an alternate serial path for systems that need to bridge a legacy peripheral. These features support compact designs in which both USB enumeration and application-specific control are required.
Typical applications include USB Type-C configuration-channel controllers, peripheral interface bridges, cable and adapter electronics, industrial USB-to-serial equipment, and embedded systems that need Billboard enumeration alongside I2C or UART. The 4 mm by 4 mm QFN package supports space-constrained products, although its exposed-pad land pattern requires careful PCB layout and adequate copper for heat dissipation.
Designers should follow the manufacturer pin-description and layout guidance when assigning the 24-QFN connections. Place USB routing impedance-controlled, keep the termination and interface paths compact, and verify device power requirements against the manufacturer datasheet. Confirm the complete pin configuration, voltage ratings, and exposed-pad connection before releasing the PCB artwork.

主な用途
CY7C65210-24LTXIT の用途: 6 件s: USB Type-C Configuration Interface, USB-to-I2C Peripheral Bridge, USB Serial Adapter, Industrial USB Monitoring Module, Cable and Adapter Electronics, Embedded Configuration and Enumeration Hub.
USB Type-C Configuration Interface
The CY7C65210-24LTXIT fits USB Type-C products that need a dedicated Billboard controller for host-visible configuration. Its USB 2.0 full-speed interface operates at 12 Mbps, while native Billboard Device Class Driver support simplifies enumeration. The I2C master interface reaches 400 kHz and provides 190-byte transmit and receive buffers for peripheral commands. In a Type-C accessory, the controller can present device capabilities while communicating with an application processor through I2C, UART, or GPIO.
おすすめ
USB-to-I2C Peripheral Bridge
The CY7C65210-24LTXIT can bridge a USB full-speed host to an I2C master peripheral. Its single I2C channel supports operation up to 400 kHz, and the independent 190-byte transmit and receive buffers accommodate short command and response sequences. This arrangement is useful when a product needs USB enumeration and configuration while an external sensor, display, or control device remains connected through I2C.
おすすめ
USB Serial Adapter
A USB serial adapter can use the CY7C65210-24LTXIT to combine a 12 Mbps full-speed USB interface with UART and I2C connectivity. The controller's Billboard class support allows the host to recognize the adapter as a defined USB function instead of relying on a generic human-interface device. GPIO resources provide additional control or status signaling, while flash memory supports local configuration storage for adapter behavior and identification.
おすすめ
Industrial USB Monitoring Module
The CY7C65210-24LTXIT supports compact industrial monitoring modules that combine a USB host connection with embedded control peripherals. USB full-speed operation at 12 Mbps is appropriate for configuration and status traffic, while the I2C master interface can reach 400 kHz for sensors and register-based devices. GPIO adds discrete monitoring or control lines, and flash memory provides a local location for identifiers, calibration data, and device-specific settings.
おすすめ
Cable and Adapter Electronics
The 4 mm by 4 mm 24-QFN package makes the CY7C65210-24LTXIT suitable for space-constrained cable and adapter electronics. The controller combines USB 2.0 full-speed signaling, I2C, UART, GPIO, flash memory, and integrated USB termination resistors in one compact device. That integration reduces the number of separate interface components while allowing an adapter to expose configuration, status, or control information to a USB host.
おすすめ
Embedded Configuration and Enumeration Hub
The CY7C65210-24LTXIT can serve as a configuration and enumeration interface in embedded systems that require more than a basic USB data path. Native Billboard Device Class Driver support identifies the function to the host, while I2C and UART provide links to application-specific controllers. With 190-byte transmit and receive buffers, the device supports short command exchanges, and its GPIO and flash-memory resources can handle status lines and persistent configuration data.

設計ノート
Use the manufacturer package drawing and pin-description table when allocating all 24 QFN lands. Preserve the exposed-pad geometry and thermal-via pattern shown in the reference layout, and place decoupling connections directly at the relevant supply and ground pins. The compact 4 mm by 4 mm footprint leaves little routing margin, so verify every pad and paste-layer dimension against the current manufacturer package drawing before fabrication.
Keep the USB D+ and D+ routing symmetrical and controlled according to the manufacturer layout guidance. Because the controller includes integrated USB termination resistors, avoid adding a redundant termination network without first checking the schematic recommendation. Route the full-speed USB pair away from switching nodes and noisy I2C, UART, and GPIO paths, and minimize branch stubs between the controller and external connector.
Do not assume that a shared 24-QFN outline alone proves replacement compatibility. The CY7C65210A-24LTXIT adds an explicitly listed serial interface, so verify supply pins, enable behavior, I2C mapping, firmware support, and exposed-pad requirements before substituting it. Use the manufacturer pin table to confirm unused connections and follow the documented reference circuit for decoupling and configuration.
