A USB-serial bridge is an interface controller that connects a USB host to peripherals using industrial or embedded serial protocols. Within the interface-controller hierarchy, the CY7C65215 combines a full-speed USB controller, dual-channel serial interface logic, configuration flash memory, an oscillator, and a voltage regulator. This integration reduces the number of external host-interface components while preserving support for common embedded communication standards.
The principal features include 12 Mbps USB 2.0 operation, dual-channel UART, I2C, and SPI support, CapSense integration, and battery charging detection. Its two serial channels can be assigned independently, allowing one peripheral port to combine USB-to-UART conversion with USB-to-I2C or USB-to-SPI connectivity. The integrated configuration memory supports device setup, while the integrated regulator and oscillator reduce external support-circuit requirements.
Internally, the CY7C65215 is a full-speed USB controller with dedicated dual-channel serial bridging. Infineon describes the CY7C65215 and CY7C65215A as a common device family supporting UART, SPI, I2C, CapSense, and battery charging detection. The A revision is presented as a distinct ordering variant, so firmware, electrical conditions, and lifecycle status should be checked before using it as a substitution.
Typical uses include industrial control panels, USB-connected programmers, serial instrumentation, capacitive-control front panels, battery-powered USB accessories, and embedded systems that need one USB port to serve more than one peripheral interface. The 32-QFN package also supports compact designs where connector density and board area are important.
Designers should follow the manufacturer pin-description table when assigning USB, serial, supply, ground, and exposed-pad connections. Confirm the exact channel configuration, supported protocol modes, oscillator requirements, input limits, and decoupling recommendations in the manufacturer datasheet before finalizing the PCB. Firmware support should also be matched to the selected CY7C65215 or CY7C65215A revision.
This page consolidates manufacturer specifications, ordering information, verified distributor listings, application guidance, and drop-in replacement analysis to support faster engineering selection. It focuses on practical differences among documented family members while avoiding unsupported assumptions about unreleased or cross-brand equivalents.

Applications typiques
CY7C65215-32LTXIT convient pour 6 applications: Industrial USB Control Panel, USB-to-UART and USB-to-I2C Programmer, Capacitive-Touch USB Peripheral, Battery-Powered USB Accessory, USB Serial Test and Measurement Adapter, Embedded Service and Configuration Interface.
Industrial USB Control Panel
The CY7C65215-32LTXIT is well suited to a compact industrial control panel because it combines 12 Mbps USB 2.0 with two configurable serial channels supporting UART, I2C, and SPI. The host can use one channel for a controller while the other connects to a display, sensor, or configuration interface. Integrated CapSense can support sealed capacitive buttons or controls, while battery charging detection can assist USB-powered accessories. The 32-QFN 5 x 5 mm package limits board footprint, and the integrated regulator, oscillator, and configuration flash reduce external support components. Firmware, isolation, grounding, and peripheral voltage compatibility should be validated for each panel architecture.

USB-to-UART and USB-to-I2C Programmer
The CY7C65215-32LTXIT can bridge a USB host to a target containing both UART and I2C peripherals, reducing the need for separate USB adapters in a programming fixture. Its two configurable serial channels support UART, I2C, and SPI, while 12 Mbps full-speed USB provides a practical host interface for configuration and firmware transfer. Integrated configuration flash and an on-chip oscillator simplify the bridge implementation. Use the manufacturer datasheet to assign the channels, confirm logic voltage levels, and implement ESD protection where the cable leaves the enclosure. Host-driver and target-protocol support must be tested against the exact firmware configuration.
Recommandé
Capacitive-Touch USB Peripheral
Integrated CapSense makes the CY7C65215-32LTXIT useful for USB peripherals that combine data communication with a capacitive user interface. A single 12 Mbps USB 2.0 connection can provide both serial peripheral connectivity and touch sensing, enabling front panels, access controls, and instrument selectors to avoid a separate touch controller. The dual-channel architecture can connect UART, I2C, or SPI peripherals while the CapSense section evaluates capacitive electrodes. Follow the manufacturer reference circuit for electrode sizing, scan timing, grounding, and noise immunity. Environmental qualification and USB cable-length behavior should be checked in the final enclosure.
Recommandé
Battery-Powered USB Accessory
The CY7C65215-32LTXIT can serve as the interface controller in a battery-powered USB accessory that needs both peripheral connectivity and source-charge detection. Its battery charging detection is compliant with USB Battery Charging Specification Rev. 1.2, while dual UART/I2C/SPI channels support sensors, actuators, or configuration interfaces. The full-speed USB 2.0 interface operates at up to 12 Mbps, which is appropriate for control traffic and moderate data-transfer workloads. Battery-system design still requires separate power-path management, current sensing, protection, and discharge control. Confirm the bridge's electrical limits and charging-policy behavior in the manufacturer datasheet.
Recommandé
USB Serial Test and Measurement Adapter
The dual-channel CY7C65215-32LTXIT is suitable for compact test and measurement adapters that bring legacy or embedded serial instruments to a USB host. One channel can operate as UART while the other provides I2C or SPI connectivity to sensors, programmable logic, or instrument control registers. The 12 Mbps USB 2.0 full-speed interface simplifies host enumeration and configuration. Integrated CapSense can add a local touch interface on portable equipment, and the 32-QFN package supports dense adapter hardware. For laboratory use, add suitable transient protection, define grounding and isolation strategy, and verify timing margins for the connected instruments.
Recommandé
Embedded Service and Configuration Interface
The CY7C65215-32LTXIT can provide a consolidated USB service port for embedded equipment that uses more than one internal serial protocol. A host can access a UART bootloader on one channel and an I2C configuration bus on the other, or communicate with an SPI device through a configurable channel. This reduces external USB bridge count and board area while preserving familiar peripheral protocols. Configuration flash allows device-specific USB descriptors and settings to remain within the bridge design. Secure firmware loading, update authentication, and recovery behavior must be implemented at the system level rather than assumed from the USB interface alone.

Notes de conception
Use the manufacturer package drawing and pin-description table for the 32-QFN footprint, exposed pad, and pin-1 orientation. Keep USB traces short, controlled-impedance where required, and away from CapSense electrode routing and switching nodes. Place required decoupling capacitors close to their associated supply and ground pins using the shortest possible return path. The exposed-pad thermal and electrical requirements should follow the datasheet land pattern exactly.
Separate USB D+ and D- routing from UART, I2C, SPI, and CapSense inputs to reduce coupled noise and data errors. Match USB trace geometry to the board stack-up, maintain continuous reference planes, and avoid stubs or unnecessary test pads on high-speed edges. ESD protection near an external USB connector should be selected and placed according to the connector's current rating and the device's protected pins.
Do not treat the CY7C65215A family variants as identical without reviewing revision-specific firmware and electrical behavior. Likewise, do not substitute a component merely because it uses a 32-QFN package; pin function, voltage domains, exposed-pad requirements, protocol support, and configuration mechanism must match. Validate the exact CY7C65215-32LTXIT ordering code against the approved bill of materials before release.
Apply the manufacturer reference circuit for supply selection, decoupling, clock support, and configuration programming. Check the current budget for USB attachment, attached serial peripherals, internal functions, and external pull networks before selecting the system supply. For battery-powered accessories, implement source detection, charging control, reverse-current protection, and brownout behavior at the power-path level rather than relying solely on the bridge's charging-detection function.
Informations de conformité
The verified product and distributor snippets do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 qualification is not applicable because this is an interface controller rather than an automotive-qualified power device.
