CY7C65215-32LTXI - Dual USB-Serial Bridge | Infineon
MPN: CY7C65215-32LTXI ✓ Hoạt độngCY7C65215-32LTXI Tóm tắt
A USB-serial bridge is an interface controller that translates USB traffic into an embedded serial protocol. The CY7C65215 belongs to the EZ-USB serial bridge family, which sits between a USB host and UART, I2C, or SPI peripherals. Its dual-channel architecture can reduce peripheral count and consolidate communication functions within industrial, consumer, communications, and human-interface equipment.
The device supports USB 2.0 full-speed operation at 12 Mbps and integrates UART, I2C, and SPI interfaces. According to the Infineon manufacturer datasheet, it also includes CapSense and BCD functions. The BCD block is compliant with USB Battery Charging Specification Revision 1.2, while CapSense provides integrated touch-sensing capability that can reduce the need for separate sensing hardware.
The controller integrates a voltage regulator, oscillator, and flash memory for storing configuration parameters. These blocks allow a compact implementation that does not require an external configuration-storage device. The CY7C65215 also supports both bus-powered and self-powered operating modes, plus suspend and remote-wake signals for system power management.
Typical uses include USB-connected control panels, dual-serial peripheral adapters, CapSense user-interface controls, configuration tools, and systems that bridge a USB host to UART, I2C, or SPI devices. In these applications, the 12 Mbps USB link supports firmware updates, command exchange, data acquisition, and configuration traffic.
PCB implementation should preserve short USB traces, provide correct decoupling near the power pins, and route high-current USB bus connections with adequate copper width. Firmware and peripheral configuration require the USB-Serial Configuration Utility identified in the verified Infineon support material, and prototype designs should verify the selected protocol, clocking, and suspend behavior before production.
This product page combines verified manufacturer and distributor information with a practical comparison table, drop-in alternatives, application guidance, and design notes. It helps engineers evaluate the CY7C65215-32LTXI beyond basic catalog attributes while clearly identifying information that still requires confirmation from the complete datasheet.

Ứng dụng tiêu biểu
CY7C65215-32LTXI phù hợp cho 6 Áp dụngs: USB Control Panel, Dual Serial Peripheral Adapter, CapSense User Interface, USB Battery-Charging Interface, Industrial Configuration Tool, USB-to-Flash Programming Adapter.
USB Control Panel
The CY7C65215-32LTXI fits a USB control panel because it combines two serial channels with CapSense in one 32-pin QFN device. A host can use one channel for commands and another for status or peripheral data, while CapSense adds touch or proximity controls without a separate sensing controller. Its USB 2.0 full-speed link operates at 12 Mbps, which is appropriate for configuration traffic, button events, and supervisory commands. The 1.71 V to 5.5 V operating range also allows integration across common embedded voltage levels. Designers should confirm protocol pin multiplexing, configure the device with Infineon's USB-Serial Configuration Utility, and validate suspend or remote-wake behavior when the panel must remain responsive without excessive power consumption.

Dual Serial Peripheral Adapter
The CY7C65215-32LTXI is appropriate for an adapter that exposes two embedded serial peripherals through one USB connector. Its support for UART, I2C, and SPI allows a host to communicate with sensors, flash devices, or configuration targets while retaining a 12 Mbps USB 2.0 full-speed path. Integrating the voltage regulator, oscillator, and configuration flash reduces the number of support components compared with a discrete bridge design. The principal design consideration is protocol selection: each attached peripheral must have a compatible electrical interface and sufficient signal conditioning. Engineers should also review the complete datasheet for UART, SPI, and I2C timing limits before setting production baud rates or clock modes.
Được đề xuất
CapSense User Interface
The CY7C65215-32LTXI supports CapSense-based user interfaces because touch sensing is integrated into the same controller as the USB-serial functions. A compact product can use CapSense for buttons, sliders, or proximity surfaces while USB provides configuration, firmware maintenance, and data connectivity. The 12 Mbps USB full-speed interface is substantially faster than needed for ordinary touch events, leaving bandwidth for diagnostics or protocol data. Because the package is only 5 mm by 5 mm, it also supports space-constrained control surfaces. Designers should follow the manufacturer's recommended CapSense layout and grounding practice, verify finger sensitivity in the final enclosure, and confirm the exact sensing resources available in the selected device variant.
Được đề xuất
USB Battery-Charging Interface
The CY7C65215-32LTXI is suitable for a USB-connected product requiring battery-charging detection because its BCD block is compliant with USB Battery Charging Specification Revision 1.2. This allows the USB-facing circuitry to identify charging-related conditions while the serial bridge handles data communication. The 1.71 V to 5.5 V operating range supports integration near low-voltage embedded systems, while bus-powered and self-powered modes provide implementation flexibility. A design should still use the device's BCD outputs according to the datasheet and define how charging status is interpreted by the host or application processor. Verification should cover target-current advertisements, source behavior, thermal limits, and compliance with the complete USB charging requirements rather than BCD alone.
Được đề xuất
Industrial Configuration Tool
The CY7C65215-32LTXI can serve as the USB interface in an industrial configuration or test tool that must communicate with one or two embedded targets. UART, I2C, and SPI support allows the same controller to work across multiple equipment architectures, while 12 Mbps USB full-speed supports responsive firmware upload and diagnostic traffic. Its integrated regulator, oscillator, and configuration flash help create a compact bridge that can operate as bus-powered or self-powered equipment. For industrial use, the complete operating-temperature rating, isolation requirements, and grounding strategy must be verified; those values were not present in the verified excerpts. Engineers should also validate command latency, watchdog behavior, and safe reconnection procedures before deploying the tool in a production workflow.
Được đề xuất
USB-to-Flash Programming Adapter
The CY7C65215-32LTXI fits USB-to-flash programming because it provides SPI connectivity alongside USB 2.0 full-speed operation at 12 Mbps. The SPI channel can communicate with external nonvolatile memory while the USB path carries commands from a programming workstation. Integration of the voltage regulator, oscillator, and configuration flash supports a compact adapter that does not need a separate bridge controller. The verified Infineon technical discussion also identifies a SPI connection between CY7C65215 and flash in a DLP reference design. For implementation, engineers should confirm the target flash protocol, address width, write timing, and protection mechanism, and should validate that programming operations remain reliable across all voltage and temperature conditions expected in service.

Ghi chú thiết kế
Place the decoupling network immediately adjacent to the device supply pins and provide a continuous ground reference beneath the 5 mm by 5 mm QFN. Keep USB D+ and D− traces short, matched, and away from switching nodes and CapSense electrodes. Because the verified excerpts do not provide the complete reference layout or recommended capacitor values, use the manufacturer datasheet and evaluation-board layouts rather than relying on generic bulk decoupling rules.
Determine whether the board will use bus-powered or self-powered operation before laying out the power system. The CY7C65215-32LTXI supports both modes and includes a voltage regulator, but the source and load budgets must still comply with the USB power rules and the device's complete electrical limits. For self-powered designs, prevent back-feed through the USB connector and implement the manufacturer-recommended enable or power-state behavior.
Do not assume that a related CY7C6521x MPN is interchangeable merely because it uses a QFN package. Confirm pin names, alternate functions, protocol-channel allocation, CapSense resources, BCD behavior, clocking, and required configuration descriptors. The verified Infineon support material identifies USB-Serial Configuration Utility version 2.1.3.42 as supporting CY7C6521x devices; use the version appropriate to the selected controller.
Separate USB routing from sensitive UART, I2C, and SPI paths where practical, especially when the serial side connects to sensors or flash memory. For SPI programming applications, provide controlled pull-up or pull-down networks on mode and chip-select lines, verify signal levels, and account for the flash device's operating voltage. The verified DLP design evidence shows a direct SPI connection from CY7C65215 to flash, but its complete firmware and layout should be used as a reference.
Validate suspend, resume, and remote-wake behavior with the actual host, peripheral driver, and supply arrangement. The 12 Mbps USB full-speed rating describes signaling performance, not guaranteed application latency or wake time. A product intended for low-power operation should measure current in active, suspended, and remote-wake states and verify that the host policy does not leave the serial interface unexpectedly powered.
