CY7C65213-32LTXIT Descripción general
A USB-UART bridge IC is a type of interface controller that converts between a USB host port and a standard asynchronous serial (UART) port, allowing legacy serial devices to communicate over USB. Within the semiconductor hierarchy it belongs to the interface IC family, specifically USB bridge controllers, which sit between USB transceivers and application processors in a typical connectivity signal chain. Bridges handle enumeration, protocol conversion, and flow control so the host sees a standard COM port without custom drivers at the hardware level.
Key features of the CY7C65213 include a USB 2.0 Full-Speed (12 Mbps) controller, a UART transceiver supporting data rates up to 3 Mbps, RS232/RS485 protocol support, 8 configurable GPIOs, an integrated 512-byte flash for vendor customization, an internal 3.3V regulator allowing 3.3V or 5V operation, and an internal oscillator that eliminates the need for an external crystal. This high level of integration minimizes the external bill of materials to essentially a USB connector and a few decoupling capacitors.
Architecturally, the device combines the USB full-speed engine, serial interface engine, UART transceiver, and flash memory in a single low-power controller. The internal regulator and oscillator reduce design complexity and cost compared with discrete two-chip USB-to-serial solutions, while the GPIOs enable control signals such as RTS/CTS hardware flow control or status LEDs.
Typical applications include upgrading legacy UART-based devices to USB, industrial equipment with RS232/RS485 links, point-of-sale terminals, set-top boxes, and development/debug UART consoles for embedded processors. According to Infineon, the CY7C65213 is pin-to-pin compatible with the FTDI FT232R, making it a recognized drop-in replacement in 32-QFN implementations.
A key design consideration: verify the UART voltage domain, since the device operates from 3.3V or 5V via its internal regulator, and confirm flow-control pin mapping when replacing an FT232R layout because some secondary features differ.

Aplicaciones típicas
CY7C65213-32LTXIT es adecuado para 6 aplicacións: Legacy UART-to-USB Upgrade, Industrial RS485 Fieldbus Nodes, Embedded Debug and Console Ports, Point-of-Sale and Retail Peripherals, Set-Top Boxes and Consumer Electronics, USB Instrumentation and Data Acquisition.
Legacy UART-to-USB Upgrade
The CY7C65213-32LTXIT is purpose-built for adding USB connectivity to devices that already expose a UART port. Its USB 2.0 Full-Speed interface enumerates as a standard COM port on the host, while the 3 Mbps UART side covers every legacy baud rate plus high-speed extensions, so firmware changes at the far end are usually unnecessary. Because the USB controller, UART transceiver, internal regulator, and internal oscillator are all integrated, the retrofit typically requires only the QFN IC, a USB connector, and decoupling capacitors. The 512-byte flash allows vendor ID and product string customization so the upgraded product keeps its own branded identity on the host. This makes it the lowest-effort path to modernize industrial instruments, metering equipment, and legacy peripherals without redesigning their serial firmware.

Industrial RS485 Fieldbus Nodes
In industrial networks using RS485 half-duplex buses, the CY7C65213-32LTXIT serves as the USB-to-serial front end for configuration tools, gateways, and HMI panels. Infineon explicitly lists RS232/RS485 support, and spare GPIOs can drive the RS485 transceiver direction (DE/RE) pin, removing the need for automatic-direction-control hardware. The 3 Mbps UART ceiling comfortably supports standard Modbus RTU rates and faster proprietary protocols, while the internal regulator allows powering directly from a 5V industrial rail. The 32-QFN 5x5 mm package with exposed pad keeps thermal and EMI performance solid inside sealed DIN-rail enclosures. Because the part is pin-compatible with the widely deployed FT232R, existing RS485 USB adapter designs can be migrated with minimal PCB changes while gaining GPIO-based direction control.
Recomendado
Embedded Debug and Console Ports
Development boards and production fixtures rely on USB-UART bridges for processor consoles and log output. The CY7C65213-32LTXIT fits this role with its no-crystal internal oscillator, which saves board area on dense dev kits, and its 3 Mbps UART that matches high-baud console settings used by modern SoCs. SparkFun adopted exactly this IC for its USB-UART serial breakout, demonstrating its suitability for developer-facing tools with a 6-pin UART header. The 8 GPIOs provide RTS/CTS hardware flow control for reliable high-rate console capture, and the internal regulator lets the board run from USB VBUS alone. For multi-board labs, standardizing on this bridge in the 32-QFN footprint gives consistent driver behavior and pin mapping across all tooling.

Point-of-Sale and Retail Peripherals
Receipt printers, barcode scanners, and card terminals historically used RS232 serial links and now require USB for modern POS hosts. The CY7C65213-32LTXIT converts these serial ports to USB 2.0 Full-Speed with minimal redesign: the UART side reuses the existing serial firmware, and the host sees a standard COM port compatible with legacy POS software stacks. The 512-byte flash enables vendor-specific VID/PID programming so retail management software can identify each peripheral type automatically. Its low-power operation suits bus-powered handheld terminals, and the compact 32-QFN (5x5 mm) package fits slim printer and scanner mechanics. Internal oscillator and regulator further reduce component count, which matters for cost-sensitive high-volume retail hardware platforms.

Set-Top Boxes and Consumer Electronics
Consumer platforms such as set-top boxes, smart TVs, and networking appliances use USB-UART bridges for factory test ports and service interfaces. The CY7C65213-32LTXIT integrates the USB controller, UART transceiver, regulator, and oscillator in one 32-QFN (5x5 mm) package, minimizing cost and board area on high-volume consumer PCBs. Its 3 Mbps UART handles fast firmware-log streaming during production testing, while RS232 mode supports older service-tool ecosystems. The exposed-pad QFN provides robust solder-joint reliability for wave/reflow consumer assembly, and tape-and-reel (-T suffix) packaging supports automated pick-and-place at line speed. Because the part is RoHS-compliant and Pb-free, it meets the environmental regulations required for global consumer electronics distribution.
Recomendado
USB Instrumentation and Data Acquisition
Test instruments, sensor dongles, and data loggers use the CY7C65213-32LTXIT to bridge measurement MCUs to PCs. The USB 2.0 Full-Speed link sustains continuous streaming from the 3 Mbps UART, enough for multi-channel ADC data aggregation at moderate sample rates, and hardware flow control via GPIOs prevents buffer overflow during bursts. The internal regulator and oscillator let designers power the bridge and a 3.3V MCU domain directly from USB VBUS, simplifying bus-powered portable instruments. The 512-byte flash allows instrument vendors to program custom serial numbers so multiple identical loggers enumerate predictably in lab software. Its pin compatibility with the FT232R also lets instrument makers qualify this Infineon part as a second source on existing calibrated hardware designs.

Notas de diseño
The 32-QFN (5x5 mm) package has an exposed pad that must be soldered to a ground via-array on the PCB. Place a 3x3 or 4x4 grid of vias under the pad connected to the ground plane to ensure reliable grounding and thermal performance. Use a ~0.5 mm stencil opening with reduced paste coverage (50-70%) on the center pad to avoid solder voiding and component floating during reflow. Decouple the VBUS-derived supply with 0.1 uF ceramic capacitors placed within 2 mm of the supply pins, per standard Infineon EZ-USB bridge reference layouts.
When replacing an FT232R with the CY7C65213, Infineon KBA85921 confirms pin-to-pin compatibility but documents differences in secondary behavior. Verify the FT232R-specific CBUS pin functions, internal pull configurations, and driver requirements on your board before substitution. Also note that FT232RL is a 28-pin SSOP while CY7C65213-32LTXIT is a 32-pin QFN - only boards designed with the QFN footprint are true drop-in. Program the 512-byte flash with correct VID/PID and flow-control settings during production, otherwise the device enumerates with default Cypress descriptors that may confuse host software.
The internal 3.3V regulator allows operation from 5V USB VBUS without an external LDO. If powering from a 3.3V system rail instead, confirm from the datasheet whether the regulator output should be left unloaded or connected per the recommended configuration - incorrect regulator pin handling is a common bring-up failure. Estimated: at USB Full-Speed typical operating currents for this class of bridge (tens of mA), dissipation in the 32-QFN is well under 100 mW, so no thermal relief beyond the exposed pad is normally required at room ambient.
Keep the USB D+/D- traces as a 90-ohm differential pair, matched in length within 1-2 mm, and route them away from the UART lines and clock-bearing nets. Although the internal oscillator removes the crystal, this also means USB compliance depends on clean supply decoupling - noise on the regulator output can jitter the Full-Speed clock. Add series protection (e.g., a USB ESD array) at the connector side of D+/D- for field-exposed ports, consistent with Infineon's USB bridge reference designs.
