CY7C65211-24LTXI Descripción general
A USB-serial bridge is an interface IC that translates USB traffic from a host computer into UART, I2C, or SPI transactions for an embedded peripheral. The CY7C65211 family belongs to the broader hierarchy of interface controllers, USB interface ICs, and semiconductors. Its integrated configuration memory, voltage regulator, oscillator, CAPSENSE functions, and power-management features reduce the external circuitry required for a USB-connected peripheral.
According to the verified Infineon product and datasheet data, the device supports full-speed USB, 3 Mbps UART, and 400 kHz I2C. The family also supports SPI and CAPSENSE, while the CY7C65211 version is described as compliant with the USB Battery Charging Specification, revision 1.2. The target ordering code is supplied in a 24-QFN package identified by distributors as 4x4 mm.
The CY7C65211 is designed for USB connectivity in peripherals that use more than one serial protocol. A host can use the bridge for UART firmware or data links, I2C sensor access, or SPI peripheral control, depending on the device configuration. Its integration supports cost-effective implementation where an external USB transceiver, protocol converter, and separate configuration memory would otherwise be required.
Typical uses include USB-to-UART cable designs, USB-connected sensor hubs, industrial control adapters, configuration or programming interfaces, capacitive-input products, and embedded accessories that need bus-powered operation. The verified manufacturer description specifically identifies serial peripherals, USB battery charging, CAPSENSE, and USB 2.0 connectivity as core application areas.
When laying out a design, confirm the selected UART, I2C, or SPI configuration, USB signal routing, power supply requirements, and pin multiplexing against the manufacturer datasheet. Do not assume that a two-wire UART design can leave every unused serial pin unconnected without checking the device configuration requirements. This page consolidates verified manufacturer data, distributor package information, and application guidance without inventing unavailable electrical limits.

Aplicaciones típicas
CY7C65211-24LTXI es adecuado para 6 aplicacións: USB-to-UART Cable and Adapter, USB Sensor Hub, Industrial Configuration Interface, CAPSENSE User Interface, USB Battery-Charging Peripheral, Embedded Programmer and Debug Adapter.
USB-to-UART Cable and Adapter
The CY7C65211-24LTXI fits USB-to-UART adapters because it provides full-speed USB 2.0 connectivity and UART support up to 3 Mbps. Place the bridge between a USB host connector and a UART peripheral, then configure the protocol mode and verify the required serial signal levels. Its integrated voltage regulator, oscillator, and configuration memory can reduce external support circuitry. The design trade-off is that the exact UART pin usage and whether an external RS232, RS422, or other transceiver is required must be confirmed in the manufacturer datasheet.
Recomendado
USB Sensor Hub
The CY7C65211-24LTXI is suitable for a USB-connected sensor hub requiring selectable serial connectivity. Its verified support for 400 kHz I2C is useful for common sensor and control buses, while SPI support gives the product additional flexibility for peripherals that need a clocked interface. The bridge can present a standard USB connection to a host while the embedded controller manages sensor addressing and data acquisition. Firmware configuration must match the selected I2C or SPI mode, and signal voltage, pull-up, and timing requirements are not supplied in the verified excerpts.
Recomendado
Industrial Configuration Interface
The bridge fits industrial configuration and programming interfaces where a controller must be serviced through USB while the target equipment uses embedded serial signaling. Full-speed USB 2.0 provides host connectivity, and the integrated flash memory can retain configuration parameters for repeatable peripheral behavior. Use the UART, I2C, or SPI mode according to the target controller, and account for industrial temperature and EMC requirements that are not specified in the supplied data. The 24-QFN footprint also supports compact PCB designs when the manufacturer pin and layout guidance is followed.
Recomendado
CAPSENSE User Interface
Integrated CAPSENSE functionality makes the CY7C65211-24LTXI relevant to USB-connected capacitive-input products. A host can configure or monitor the peripheral through USB while the device supports CAPSENSE behavior within the same serial-bridge component. This can simplify a product that otherwise needs a separate USB interface and touch controller. The verified data does not provide electrode count, scan timing, sensitivity, or capacitance range, so those parameters must be obtained from the manufacturer datasheet before defining a sensor front end.
Recomendado
USB Battery-Charging Peripheral
The family is described as compliant with the USB Battery Charging Specification, revision 1.2, making the bridge relevant to USB-connected accessories that include battery-management or charging behavior. The CY7C65211 can bridge host control traffic to a peripheral while supporting serial command and status communication. System-level charging design still requires correct USB power-path implementation, protection, and validation against the applicable device and system requirements. The verified material does not provide input current, battery voltage, charging-current, or thermal limits for this MPN.
Recomendado
Embedded Programmer and Debug Adapter
The CY7C65211-24LTXI can be used in embedded programmer adapters where a USB host connects to a target MCU through a serial protocol. The 3 Mbps UART capability is relevant to firmware download, logging, and configuration traffic, while I2C and SPI provide options for target devices using those buses. Firmware must implement the appropriate bridge configuration and host-side driver or utility. Because the supplied data does not specify supported target protocols, signal thresholds, or timing guarantees, validate the adapter with the exact target device before production.

Notas de diseño
Use the manufacturer power and decoupling guidance for the 24-QFN device. Because the verified excerpts confirm integrated voltage regulation and both bus-powered and self-powered modes, but do not provide the exact operating-voltage range, capacitor values, or current limits, do not select external supply components from generic USB assumptions. Confirm the regulator output, input capacitance, load behavior, and power-state transitions in the datasheet.
Route USB D+ and D- as a controlled differential pair and follow the manufacturer layout guidance for the USB controller, package escape paths, grounding, and decoupling. Keep the USB connector, protection components, and bridge connection short and symmetrical. The exact trace geometry and impedance target are not included in the supplied verified data, so use the official reference layout rather than an inferred value.
Do not treat UART, I2C, and SPI as interchangeable without configuring the bridge for the intended mode. The verified community discussion specifically raises the question of whether unused UART pins can remain unconnected for a two-wire arrangement, which indicates that pin usage depends on the selected configuration. Confirm the required mode, unused-pin treatment, pull resistors, and target signal levels in the manufacturer datasheet and configuration utility guidance.
Información de cumplimiento
The supplied verified excerpts do not state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification status. These fields remain unknown rather than inferred from the manufacturer or distributor listing.
