CY7C65210-24LTXI - USB 2.0 Billboard Controller | Infineon
부품 번호: CY7C65210-24LTXI ✓ 활성CY7C65210-24LTXI 개요
A USB Billboard controller is a USB interface device that presents product identity and capability information to a host. In the device hierarchy, it is a USB interface controller within the broader class of USB controllers, interface ICs, and semiconductors. The Billboard function enables a Type-C product to expose descriptive information such as manufacturer, product, version, configuration, and other device attributes without requiring a separate human-readable interface implementation.
Key features include USB 2.0 full-speed operation, a 12 Mbps data rate, an I2C/UART interface, GPIO support, and integrated flash memory. The I2C interface supports communication with a host-side or embedded controller, while UART provides a straightforward serial connection to a microcontroller or configuration processor. The exposed GPIOs allow status LEDs, control signals, or peripheral handshakes to be managed without expanding the external component count.
The CY7C65210 combines a USB device controller with configuration storage and interface bridges. Its integrated flash reduces the need for external nonvolatile memory when the Billboard identity data and device configuration must be retained. Designers still need to confirm the supported descriptor format, programming method, and firmware update requirements against the manufacturer datasheet before committing a product configuration.
Typical applications include USB Type-C configuration-channel adapters, product identity and interface controllers, device-management accessories, industrial USB interface modules, and embedded systems that must expose identity information while retaining a serial control path. The 4x4 mm QFN package is also useful where PCB area is constrained, although thermal pad layout and exposed-pad soldering should follow the recommended land pattern.
The principal design consideration is interface partitioning: I2C and UART provide different host-to-device control models, so the system firmware and external pull-up requirements must match the selected interface configuration. USB routing also requires controlled impedance, short connection to the connector, and careful placement of protection and bypass components.

일반적인 애플리케이션
CY7C65210-24LTXI 적합 용도: 6 애플리케이션s: USB Type-C Billboard Identity Adapter, USB Type-C Configuration Channel Interface, Industrial USB Interface Module, USB Device Management Accessory, Embedded USB-to-Serial Protocol Bridge, USB-C Powered Control and Status Interface.
USB Type-C Billboard Identity Adapter
The CY7C65210-24LTXI fits a Type-C accessory that must present product identity, capability, or configuration information to a connected host. Its USB 2.0 full-speed interface operates at 12 Mbps, which is appropriate for Billboard enumeration and control traffic rather than bulk data transfer. Integrated flash memory can retain device descriptor data, while I2C or UART provides a path for an embedded processor to update or manage that information. The compact 24-QFN (4x4 mm) package also reduces board area compared with larger discrete implementations.

USB Type-C Configuration Channel Interface
The CY7C65210-24LTXI is appropriate for a configuration-channel implementation in which a Type-C host exchanges control information with an accessory controller. The I2C and UART interfaces allow the host-facing USB function to connect to a local processor using whichever protocol the product architecture already supports. Its 12 Mbps full-speed USB link is well matched to short control exchanges, and the integrated flash supports configuration retention. Firmware should verify the Billboard fields and descriptor update sequence required by the target Type-C ecosystem.
추천
Industrial USB Interface Module
The CY7C65210-24LTXI can serve as the control and identity interface in a compact industrial USB module. Industrial equipment often needs a standards-compliant USB enumeration path together with local status inputs or configuration signals; the controller combines USB 2.0 full-speed Billboard functionality, I2C/UART connectivity, and GPIO support in one 24-QFN device. Its -40°C to 85°C specified range covers many factory and industrial environments, while integrated flash reduces external storage requirements for device identity information.
추천
USB Device Management Accessory
The CY7C65210-24LTXI fits a management accessory that exposes device identity and control registers over USB. Its Billboard function supplies host-visible product information, while I2C or UART gives a local microcontroller access to configuration and status logic. The 12 Mbps full-speed USB rate is sufficient for management commands and descriptor exchange, and the integrated flash can hold persistent identity data. A production design should confirm the supported descriptor format and whether configuration is programmed through firmware, an external programmer, or a host utility.
추천
Embedded USB-to-Serial Protocol Bridge
The CY7C65210-24LTXI can be used where a system needs both USB device discovery and a separate serial control interface. A connected host sees a 12 Mbps full-speed USB device, while the embedded side communicates through I2C or UART and can use the GPIO pins for handshake signals. This division of labor allows the designer to avoid tying an application MCU directly to the USB data pins. Firmware must implement the applicable USB descriptors, Billboard data, and serial protocol because those details are not fully represented in distributor summaries.
추천
USB-C Powered Control and Status Interface
The CY7C65210-24LTXI is applicable to a USB-C accessory that requires enumeration and status reporting while also exposing local control signals. Its integrated flash and GPIO support reduce the need for separate identity storage and logic, and the small 24-QFN package is valuable in cable-management or inline accessory products. The 12 Mbps full-speed interface handles control traffic efficiently, but the host-side driver or configuration utility must recognize the device's Billboard implementation. Enclosure space, connector orientation, and low-power behavior require board-level validation.

설계 노트
Route the USB D+ and D- pair as a controlled-impedance differential pair with continuous reference to the connector, minimal stubs, and no intervening test pads that lack high-speed return paths. Place ESD protection close to the connector and bypass capacitance close to the device supply pins. For a 4x4 mm QFN, the exposed pad requires the manufacturer's recommended land pattern, adequate solder-mask definition, and thermal-via guidance.
Budget the USB supply current for the controller, flash, external I2C or UART loads, and attached pull-up networks. I2C pull-ups should not be placed directly on the USB D+ or D- conductors, and excessive bus capacitance can slow edges and degrade communication margin. Confirm the absolute maximum and operating voltage limits, undervoltage behavior, and required decoupling directly from the manufacturer datasheet before finalizing the power tree.
Do not treat the A-suffix order code as interchangeable solely because the package matches. Before substituting CY7C65210A-24LTXI for CY7C65210-24LTXI, compare pin names, exposed-pad connection, descriptor and Billboard behavior, flash capacity, firmware requirements, and the manufacturer's change documentation. A package match establishes mechanical compatibility only; it does not establish firmware or descriptor compatibility.
Keep the I2C and UART routing physically separated from the USB differential pair where practical, particularly near connector and protection-device regions. Provide clean return paths for high-speed edges, avoid long stubs on flash or configuration nets, and validate the assembled board with an appropriate USB analyzer. Billboard enumeration failures can result from descriptor data, signal integrity, supply noise, or host-driver expectations, so isolate those variables during bring-up.
규정 준수 정보
RoHS compliance is stated in the verified distributor data. The verified material does not provide REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations; the -40°C to 85°C industrial temperature rating does not by itself establish AEC-Q100 qualification.
