MPN: CY7C65213-32LTXI ✓ فعالCY7C65213-32LTXI نمای کلی
A USB-UART bridge is an interface IC that converts a USB host connection into a conventional serial UART link. It belongs to the USB interface-controller hierarchy, connects a computer or USB host to embedded equipment, and reduces the need for a separate USB transceiver and UART controller. The CY7C65213 family is intended to modernize legacy UART-based equipment while preserving familiar serial communication in cables, test systems, industrial controls, and development boards.
The principal verified features include USB 2.0 Full-Speed operation, UART data signaling up to 3 Mbps, eight general-purpose I/O pins, and support for RS232 and RS422 interfaces. Its integrated bridge architecture can simplify host-side peripheral enumeration and reduce the external component count. The 32-QFN package is compact but requires careful PCB layout and exposed-pad thermal management according to the manufacturer footprint guidance.
The device also supports low-power behavior through its SLEEP# assertion when the USB bus enters suspend, a feature described in the manufacturer datasheet as helping meet stringent USB 2.0 suspend-current requirements in bus-powered systems. This makes the bridge relevant to portable and embedded USB equipment where standby current matters. Exact operating-voltage, temperature, GPIO-drive, and power-consumption values must be confirmed from the complete manufacturer datasheet.
Typical applications include USB-to-UART adapters for embedded development boards, industrial serial gateways, laboratory test equipment, configuration interfaces, printer or peripheral adapters, and retrofit products that previously relied on a legacy UART connector. The bridge can be paired with a host MCU when a system needs protocol processing, or with level-shifting and protection components when the external serial interface must connect to longer or industrial cable runs.
For a new design, verify the exact package pinout, voltage limits, crystal or clock requirements, UART electrical standard, and host-driver behavior before layout release. USB signal routing should follow the manufacturer reference layout, with controlled differential impedance and short connector-to-device paths. The principal engineering trade-off is integration and footprint savings versus the need to validate suspend current, signal integrity, and driver compatibility on the completed host system.
This page combines the verified manufacturer and distributor information with practical interface-bridge selection guidance, while marking unspecified electrical details for datasheet confirmation rather than estimating them.

کاربردهای معمول
CY7C65213-32LTXI مناسب است برای 6 کاربردs: USB-to-UART Development Adapter, Industrial Serial Gateway, Laboratory Test and Measurement Interface, USB-to-RS232 Peripheral Retrofit, USB Configuration Interface, Embedded USB Serial Monitor.
USB-to-UART Development Adapter
CY7C65213-32LTXI fits a compact USB-to-UART adapter for programming, console access, and bring-up of embedded boards. Its verified USB 2.0 Full-Speed interface and 3 Mbps UART capability provide a practical bridge between a modern host and a legacy serial connector, while eight GPIOs can expose bridge-control or peripheral-status signals. The designer should confirm supply limits, clock requirements, pinout, and host-driver support from the manufacturer datasheet. Use controlled USB routing, local decoupling, and a protection strategy appropriate to the connector and cable environment. The main benefit versus a discrete USB transceiver plus UART controller is reduced integration effort; the trade-off is that software compatibility and electrical-level behavior must be validated as a complete bridge product.

Industrial Serial Gateway
CY7C65213-32LTXI can serve as the host-facing USB-to-UART stage in an industrial serial gateway when the external link uses RS232 or RS422. The verified 3 Mbps UART rate supports higher-speed serial traffic than common low-rate console links, and the eight GPIOs can support reset, direction, status, or peripheral-control functions. The IC does not by itself provide the full industrial protection network: add transient-voltage suppression, isolation where required, grounding, and connector-level surge protection. Check the complete datasheet for temperature range, ESD limits, and electrical thresholds before assigning it to a factory environment. Its compact 32-QFN 5 mm × 5 mm package helps reduce board area, but careful exposed-pad layout and USB signal-integrity routing remain necessary.
پیشنهادی
Laboratory Test and Measurement Interface
CY7C65213-32LTXI is useful for laboratory adapters that expose a UART-based instrument, fixture, or controller to a USB host. The verified 3 Mbps UART capability can shorten transfer time compared with lower-speed serial links, while USB Full-Speed keeps the host connection simple and widely available. Eight GPIOs can be mapped to trigger, ready, fault, or relay-control signals if the host software supports them. For bench equipment, place the bridge close to the USB connector, keep the USB differential pair impedance-controlled, and provide a stable reference and decoupling network. Validate ground offsets and cable transients because the bridge’s verified specifications identify supported RS232/RS422 functionality but do not provide complete industrial EMC or isolation ratings in the supplied data.

USB-to-RS232 Peripheral Retrofit
CY7C65213-32LTXI can update an existing peripheral that exposes only an RS232 UART connector, allowing the enclosure to gain a USB host interface without replacing the original serial protocol logic. The manufacturer product page specifically identifies RS232 support, and the bridge’s 3 Mbps UART rate covers applications that need more than a slow diagnostic port. The external RS232 driver, connector, and protection components remain necessary and must be selected according to cable length, ground reference, and ESD requirements. Firmware should be tested for boot enumeration, suspend/resume behavior, flow control, and driver installation. Compared with an FT232R-based design, the Infineon community result indicates pin-to-pin compatibility but also warns that differences must be reviewed before using it as a replacement.

USB Configuration Interface
CY7C65213-32LTXI can provide a dedicated USB configuration path for equipment that normally uses a UART only during manufacturing, calibration, or field service. The USB Full-Speed interface allows a service laptop to connect without opening the product, and the eight GPIOs can be assigned to boot selection, reset, status indication, or service-enable functions where the board design supports them. SLEEP# asserted during USB suspend can help the product enter a lower-power state when the host stops the session. Place the bridge in a controlled power branch and account for inrush, host enumeration, and suspend current. The exact drive strength, voltage levels, and GPIO multiplexing must be confirmed from the datasheet; the verified data does not provide a complete pin-level map.
پیشنهادی
Embedded USB Serial Monitor
CY7C65213-32LTXI is suitable for an embedded USB serial monitor that bridges a host computer to a controller, sensor, or power subsystem. Its verified eight-GPIO count allows the design to monitor reset-ready, fault, mode, or latch signals in addition to the UART data path. The compact 32-QFN footprint helps keep the bridge close to the connector and away from high-current switching nodes, while USB Full-Speed supports straightforward enumeration through standard host controllers. For reliable operation, follow the manufacturer’s USB layout guidance, provide local input/output decoupling, and use a ground strategy that controls cable-borne noise. The bridge does not guarantee a particular host-driver environment; software installation and operating-system support must be confirmed separately for the intended product release.

یادداشت‌های طراحی
Route the USB differential pair as a short, impedance-controlled pair directly between the USB connector and CY7C65213-32LTXI. Avoid stubs, test pads, and unrelated high-current paths between the transceiver pins. Use the manufacturer reference layout for layer stack-up, pair spacing, grounding, and decoupling because the supplied verified data confirms USB 2.0 Full-Speed operation but does not provide a complete PCB stack-up recommendation.
Validate USB VBUS power, inrush, local decoupling, and suspend-current behavior on the assembled board. The verified manufacturer result states that SLEEP# asserts when USB enters suspend to help meet stringent suspend-current requirements. Use that signal to place downstream circuitry into a defined low-power state, but confirm its polarity and timing in the complete datasheet before relying on it for power sequencing.
Treat the 32-QFN as a compact high-density footprint requiring careful land-pattern and exposed-pad design. Follow the official package drawing and recommended land geometry rather than deriving dimensions from the distributor snippet. Keep the USB connector and bridge close together, provide a continuous ground reference where appropriate, and inspect solderability, paste volume, and assembly rework constraints during PCB bring-up.
Do not substitute a USB-UART IC solely because it is also marketed as USB-to-serial. Check package pins, supply voltage, clock architecture, UART logic levels, external RS232/RS422 circuitry, host drivers, suspend behavior, and firmware compatibility. Infineon’s verified FT232R replacement guidance is useful starting evidence, but it explicitly notes differences that must be reviewed before a production substitution.
