CY7C65213-28PVXI Overview
A USB-to-UART bridge is a class of bridge controller that translates between the USB protocol on the host side and an asynchronous serial (UART) interface on the device side, allowing legacy RS-232-style peripherals to gain modern USB connectivity without redesign. Within the broader product taxonomy, the CY7C65213 sits at the hierarchy: USB bridge controller -> interface IC -> communication IC -> semiconductor device. Its integrated regulator removes the need for an external 3.3V supply, and its internal oscillator removes the need for an external crystal, simplifying the BOM to a handful of decoupling capacitors.
Key features include USB 2.0 Full-Speed (12 Mbps) compliance, support for USB suspend and resume signalling, hardware and software flow control ( RTS/CTS and XON/XOFF), integrated 512-byte flash for custom VID/PID and descriptor storage, configurable GPIO, and an industrial operating temperature range of -40C to +85C. The internal LDO supports bus-powered or self-powered configurations as defined by the USB 2.0 specification, simplifying the upstream power-section design.
Architecturally, the CY7C65213 uses a serial interface engine (SIE) for USB protocol handling and a dedicated UART block with FIFO buffers, offloading all USB enumeration and protocol management from the host MCU. This lets designers replace legacy RS-232 transceivers with a single chip and a USB connector, reducing board area, BOM cost, and firmware complexity.
Typical applications include USB-to-serial dongles for embedded debugging, industrial sensor readout with USB connectivity, point-of-sale (POS) terminals that expose legacy UART peripherals to PCs, and upgrade modules for legacy RS-232 equipment. The integrated flash also supports manufacturer-specific descriptors, allowing direct use as a branded device rather than requiring a generic-CDC driver.
When designing with the CY7C65213, treat the VBUS and D+/D- lines as a controlled-impedance 90 ohm differential pair (per USB 2.0), and place the internal-regulator decoupling capacitors (typically 1uF and 0.1uF ceramic) within 1-2 mm of the VCCD pin. Note that the 28-SSOP variant is pin-to-pin compatible with the FTDI FT232R-style footprint when migrating designs across bridge vendors.

Typical Applications
CY7C65213-28PVXI is suitable for 6 applications: USB-to-Serial Debug Dongle, Industrial Sensor Readout with USB, Point-of-Sale (POS) Terminal, Legacy RS-232 Equipment Upgrade, USB CDC-ACM Dongle for Headless Embedded Boards, Field-Programmable USB Module.
USB-to-Serial Debug Dongle
The CY7C65213-28PVXI is well-suited as a USB-to-serial debug dongle for embedded engineers, where its integrated 3.3V LDO and internal oscillator eliminate the need for external crystals or regulators. Compared to legacy bridges, its 3 Mbps UART data rate exceeds the 115.2 kbps RS-232 ceiling, letting engineers dump firmware logs over USB at full MCU speed. The 28-SSOP package fits on tiny dongle PCBs with only a USB connector, decoupling caps, and a D+ pull-up, and the internal 512-byte flash lets you customize VID/PID without an external EEPROM.
Recommended
Industrial Sensor Readout with USB
In industrial sensor readout designs, the CY7C65213-28PVXI's industrial -40C to +85C operating range and integrated LDO simplify factory-floor installations running off USB bus power. Its 3 Mbps UART handles high-rate data acquisition streams from MCUs sampling sensors at kHz rates, while the GPIO pins can be repurposed as sensor-enable or status-indicator lines. The internal flash allows OEM-specific VID/PID pairing so factory test software recognizes boards without needing separate driver installations.
Recommended
Point-of-Sale (POS) Terminal
POS terminals often integrate a USB-UART bridge to expose a legacy UART cash-drawer or printer interface to a modern PC host, where the CY7C65213-28PVXI's CDC-ACM enumeration removes the need for vendor-specific drivers. The integrated 5V-tolerant USB transceiver survives hot-plug events at retail counters, and the internal LDO draws cleanly from the USB VBUS supply without an external regulator. Support for hardware RTS/CTS flow control is essential for sustained bidirectional traffic to peripherals like barcode scanners and receipt printers.
Recommended
Legacy RS-232 Equipment Upgrade
When upgrading legacy RS-232 equipment to USB, the CY7C65213-28PVXI drops in on the existing 28-SSOP-style PCB and replaces discrete UART transceivers plus external voltage regulators with one device. Its 3 Mbps UART ceiling far exceeds the typical 115.2 kbps requirement of legacy instrumentation, while the CDC-ACM class device profile lets the host PC recognize the equipment as a virtual COM port without custom drivers. The internal flash for custom VID/PID preserves the OEM brand on the host side, important for medical and lab-instrument applications where device identity matters.
Recommended
USB CDC-ACM Dongle for Headless Embedded Boards
For headless embedded boards (routers, IoT gateways, single-board computers) that lack on-board USB-to-serial, the CY7C65213-28PVXI is a small-footprint, 5V-tolerant bridge that takes USB VBUS and exposes a 3.3V UART to the main MCU. The integrated regulator simplifies the power section, and the low power-down suspend current (USB suspend-compliant) is critical for battery-backed or energy-conscious designs. The pin-to-pin 28-SSOP layout matches popular FT232R-based reference designs, allowing single-step BOM swaps during refresh cycles.
Recommended
Field-Programmable USB Module
OEMs building field-programmable USB modules for device firmware update (DFU) workloads benefit from the CY7C65213-28PVXI's 512-byte internal flash for storing vendor-specific descriptors and the standard 28-SSOP footprint for stable supply chain. The integrated regulator and oscillator reduce total BOM to under ten components, which is ideal for low-cost DFU cables shipped in the millions. The RTS/CTS hardware flow control ensures robust flash-loader traffic at 1 Mbps, while CDC-ACM driverless enumeration reduces customer-side installation friction.

Key Differentiators
- Fully integrated LDO + oscillator + flash in single 28-SSOP chip (vs FT232RL)
- 3 Mbps UART exceeds legacy RS-232 ceiling (vs CP2102N-A02-GQFN28)
- CDC-ACM driverless enumeration (vs FT232RL)
- A-variant offers RS-485 in same footprint (vs CY7C65213-28PVXI base part)
Design Notes
Treat the D+ and D- traces as a 90-ohm differential pair (per USB 2.0 spec) with matched length to within 150 mil. Place the decoupling capacitors (1uF bulk + 0.1uF ceramic) for VDDD within 1-2 mm of the IC pin. The ESD protection array (if used externally) should be placed immediately adjacent to the USB connector, ahead of any ferrite or common-mode choke, so that ESD events do not propagate into the bridge IC.
When migrating from FT232R to CY7C65213, add clamping diodes on the DTR pin: there is a documented latch-up susceptibility in some circuits when DTR is exposed to transient voltages above the device absolute maximum. Per the Infineon community KB, ensure VBUS decoupling is solid (10uF + 0.1uF) and that no strong inductive load shares the same VBUS rail. The CDC-ACM enumeration may also require an .inf file on legacy Windows XP systems, although Vista and later load it automatically.
The internal 3.3V LDO is intended for the bridge's own logic and modest external loads (decoupling, weak pull-ups) only - do not source more than a few mA from VDDD for downstream MCUs. For self-powered designs, add a 4.7uF bulk capacitor on VBUS to satisfy USB inrush current requirements during hot-plug events. The suspend current should be budgeted into battery-powered designs to maintain USB compliance when the host goes into S3 suspend state.
